Ma’aden and Hexagon partner on Middle East’s first ‘digital mine’ at Mansourah Massarah

Ma’aden and Hexagon have partnered to launch what they say is the Middle East’s very first digital mine, with Hexagon’s life-of-mine technology solutions being deployed at Mansourah Massarah mine, combining sensor, software and autonomous technologies to enhance efficiency, productivity, quality and safety across the mine’s operations.

Duncan Bradford, Executive Vice President Base Metals and New Metals, Ma’aden, said: “This partnership strongly aligns with our digitisation strategy, as we work to use the vast amounts of data that we mine to make our mine safer and more efficient. We look forward to working closely with Hexagon to implement and utilise the region’s first digital mine to elevate Mansourah Massarah’s operations.”

Nick Hare, President of Hexagon’s Mining division, said: “We are excited to help bring to life this important shift toward digitisation of the mine, one that holistically leverages intelligent data and automation across workflows to minimise the impacts of mining while simultaneously improving safety, productivity and operational efficiency.

“This is about co-authoring the next chapter of mining in this region with a partner who shares in our drive toward a sustainable future.”

Mansourah Massarah, Ma’aden’s newest, largest, and most technologically advanced gold mine, is in Al Khurmah governorates in Makkah Region. The mine consists of the Mansourah and Massarah resources, which are being developed as conventional open-pit mines. The 4 Mt/y plant employs carbon-in-leach and pressure oxidation processes and autoclave technologies for ore gold production. It reached a major milestone of producing first gold in September 2022, going on to produce 11,982 oz for the year.

Amelia: the underground drilling conversation starter

Some 16 months after launch, Sandvik’s AutoMine® Concept Underground Drill, also known as ‘Amelia’, is having the impact Sandvik Mining and Rock Solutions was hoping for, influencing most forward-looking conversations it is having with new and existing underground drilling clients.

The AutoMine Concept Underground Drill, launched at the company’s Test Mine in Tampere, Finland, in September 2022, is a fully autonomous, twin-boom development drill rig capable of drilling without human interaction. The cabinless unit can plan and execute the entire drilling cycle from tramming to the face, setting up for drilling, drilling the pattern and returning home to charge for the next cycle – all on battery power.

Amelia – a name that was attached to the vehicle due to its industrious connotations – was designed to showcase next-generation intelligent automation and other new technologies and features that will be introduced for current and future Sandvik offerings.

Sandvik’s underground drilling team is now that much closer to having identified what these features are.

“Amelia was always designed as a conversation starter, and that has certainly proven true,” Patrick Murphy, President, Underground Drilling Division at Sandvik Mining and Rock Solutions, told IM and a select group of trade journalists during a recent visit to the Test Mine. “Hundreds and hundreds of clients have seen this vehicle since launch, and we have had a lot of feedback; much of it proving very valuable.”

From speaking to Murphy and the AutoMine team, it is apparent many customers would have liked to acquire one of these concept machines upon launch in September, however its true value remains as a technology demonstrator for testing and development purposes.

Amelia uses a SLAM-based algorithm to improve tramming and localisation accuracy

The self-contained drill has no cable, being powered instead off an on-board battery. It uses and optimises power and electricity based on need, making that power supply last even longer. Automated tramming, mission management, drilling and bit changing are some of the elements Sandvik highlighted upon launch, and much of the initial customer discussion has centred around these features.

“Having a machine that is sitting here in the Test Mine, is tangible, functional and can be demonstrated, allows us to have these practical conversations with customers, more so than any model we could put up on a screen,” Murphy said.

One of the elements that has caught the attention of customers is an automated lifter tube installer that removes personnel from the face charging procedure.

“When speaking to many operators, the potential to automate lifter tube installation keeps coming up,” Murphy said. “These tubes – installed in the bottom rows of a drill pattern to ensure no cuttings or muck from the holes above fill the previously-drilled holes – typically require a ‘nipper’ or ‘offsider’ to come in beside the face of the drill for installation. The potential to remove this person from this hazardous environment has really captured the attention of customers.”

The automated process Amelia currently uses for lifter tube installations is unlikely to be commercialised, but a variant of it could feature on the underground development drills in the future.

Some other elements included on the concept vehicle likely to come into the commercial drilling line-up include an artificial intelligence-guided automatic drill bit changer to identify when bits are worn and then, changed automatically, a SLAM (simultaneous localisation and mapping)-based algorithm to improve tramming and localisation accuracy and, of course, battery-backed drilling.

Amelia is designed to drill a whole round off battery power, and Murphy says a commercialised, economic option would be of interest to customers.

“If we can offer that cost-effectively compared with a diesel-powered machine, then there would be a market pull,” he said. “The solution isn’t there yet, but the flexibility showcased with Amelia – in not having to supply cables or water hoses during operation – has been highlighted by many customers we have interacted with.”

Johannes Välivaara, Vice President R&D and Product lines in the Underground Drilling Division at Sandvik Mining and Rock Solutions, says the commercialisation of RockPulse technology for continuous rock mass feedback to optimise drilling performance will be on the underground drilling roadmap, too.

“Rock Pulse has been built to measure the stress vibrations going in and out from the hole through drilling consumables,” he said. “This is a future upgrade for our drills as this real-time rock information will allow operations to make plans for ground support and get the geotechnical information off the unit in real time.”

RockPulse technology already featured on Amelia could be further integrated on commercial drill rigs with geoSURE, a rig-integrated, high precision, online rock mass analysis and visualisation system initially developed for tunnelling process optimisation. geoSURE is an important tool for the assessment of rock reinforcement or injection requirements, as well as serving as an assisting tool for charging and blasting control and geological mapping, according to the OEM.

“This (geoSURE) could be further enhanced when RockPulse is integrated into it,” Välivaara said. “It is currently only available for face drilling applications but will come into the longhole drilling space, too.”

Amelia, in this case, has not just lived up to her ‘industrious’ and ‘hardworking’ traits, she has also acted as a catalyst for change.

For example, since launch, automated options for longhole drilling have risen to the surface in customer discussions. And it is hard to see AutoMine for Underground Drills having been introduced as quickly as it has without this concept vehicle having launched.

This platform, which enables operators to remotely and simultaneously control and supervise multiple automated Sandvik underground longhole drills, can increase efficiency, safety and overall productivity in mining operations.

It has also put Sandvik in a club of its own; being the only OEM able to offer a unified traffic management system for drills, loaders and trucks. This means all three types of automated equipment can be operated and tram within the one AutoMine-controlled zone.

Testing: the secret sauce of Sandvik R&D

Jani Vilenius has his plate full at Sandvik Mining and Rock Solutions. As Director of Research and Technology Development, he is brought into most conversations the business area has about future mining products.

In fact, he even works across the Sandvik Rock Processing business area on occasion, as well as overseeing the design centre in Bangalore, India, which provides “value engineering” across Sandvik Mining and Rock Solutions divisions.

“We coordinate research programs and projects, not products,” Vilenius told IM recently in the company’s newest office in Tampere, Finland. “This may be overseeing the concept machines that we have been producing for several years, as well as technology partnerships with universities.

“We aim to think long term within the Research and Technology Development and Services team, but not too long term as the world is much more agile nowadays than it used to be.”

This means Vilenius’ team has to coordinate all of the activities taking place at the Test Mine in Tampere, provide a ‘steer’ on engineering services and safety processes needed to satisfy today’s and tomorrow’s requirements and regulations, drive cybersecurity and sustainability developments across Sandvik Mining and Rock Solutions in the R&D phase, plus integrate the thinking between the rapidly-expanding Digital Mining Technologies division within Sandvik Mining and Rock Solutions and the R&D team.

And, as of a month ago, his team also coordinates testing at the new Surface Test Pit: a new surface mining test bed being developed 40 km northwest of the underground test mine.

This is all underwritten by the strategic priorities across the business area he primarily works in, as well as the Sandvik group goal of ensuring 25% of revenue comes from products that are less than five-years-old.

To tackle these tasks, he has a sandbox (soon to be two) that all equipment providers would like to have.

The Test Mine in Tampere comes with 6 km of tunnels at a depth of 40 m, with potential to expand further. Positioned beside a glass factory and close to the company’s rock drills factory, this test mine offers the company and its customers everything they need to make strategic business decisions in an environment that can, for instance, replicate the heat and humidity of a deep underground mine in South Africa, as well as the biggest and widest mine galleries the industry has on offer.

This facility – which has everything your typical underground mine has except a daily throughput target – allows the company to run all its underground drills through a rigorous testing procedure prior to customer dispatch. It also allows the various divisions under the business area a chance to test out prototypes, applications and products from time to time.

For the concept machines Sandvik is becoming renowned for, the test mine acts as a place to validate conceptual thinking in a real-life environment, helping engage customers in detailed discussions as to what on-board and off-board technology elements would provide the greatest value to their operations in the near-, medium- and long-term.

The aim is to replicate this process on surface with the Surface Test Pit, providing the catalyst the company needs to reach its ambitious surface drilling market goals over the next several years.

IM sat down with Vilenius to find out how he coordinates all this R&D work, and how day-to-day testing works from a practical perspective.

IM: I imagine your department is inundated with requests from various business lines when it comes to testing. How do you go about prioritising these requests and turning them into an easy-to-follow roadmap that can lead to commercial solutions?

JV: I’ll answer that by taking a step back.

We have a technology focus built on supporting both Sandvik Mining and Rock Solutions and Sandvik group strategy. We then have roadmap items where we try to leverage technologies across many applications. These technology platforms are not always 100% suitable for both surface and underground mining, but there are elements that have similarities. For example, our latest electric concept surface rig uses the same thinking and philosophy used on other concept machines for underground. Of course, there are new elements included, but the platform thinking remains in place.

Jani Vilenius, Director of Research and Technology Development

Based on this, we have different forums and conversations with the divisions and the R&D heads, discussing together where we need to put the focus in terms of testing. There are, of course, differences in sizes of the division with those who invest a bit more in R&D entitled to more access, but we also have to remain strategic about how to capture the market attention within Sandvik Mining and Rock Solutions; knowing when and what to launch, as well as what developments will allow us to achieve the required technology momentum to support both our own internal goals and the goals set by our customers.

With all these technology developments – projects, concept machines, theoretical testing – there needs to be a value proposition. For the concept machines, for instance, there is value from a marketing perspective to showcase Sandvik as a technology leader, but there is also the value of engaging with customers in conversations that, through the actual machine development, allow them to comprehend what the technology may mean for them on a practical operational level.

This rapid agility – which I would say is unique to Sandvik – means we can receive valuable customer feedback on these concept machines before we commercialise certain elements. It allows us to effectively manage risk in a market calling out for technology breakthroughs to solve complex challenges.

IM: How many tests/trials can you have going on at the same time at the Test Mine?

JV: It varies. All underground drill products are tested there before they go out to customers, which puts a lot of load on the facility, while ensuring that when customers get these units, they have been run in an environment similar to a real-life mining operation.

Then we have new prototypes not under my remit that are tested ahead of becoming ‘products’, for example in underground drilling. Then, we have several technologies we test on a daily basis with different types of test benches and subsystems.

The reality is that we would not be as agile as we are without this test mine. It is not easy to go to a customer site and get permission to test equipment as it can negatively impact their (the customer’s) production. The ability to test at our own facility gives us a layer of comfort and confidence ahead of getting to the customer site.

We cannot try or test every application in our test mine, but those scenarios we do test provide real value.

IM: Are there plans to expand the test mine further?

JV: We have a roadmap for our test mine, but this is determined with a cost versus value equation. We don’t want to have empty tunnels without testing going on regularly.

We have all the opportunities to have a third, fourth and fifth level at the Test Mine. We have, for example, recently expanded into a new area to support our underground drill products to allow testing for that. This is a function of the offering getting wider and the need to expand the tunnels to make sure the new products receive the same testing opportunities as the existing ones.

We have expansion plans focused on automation and electrification too.

IM: Speaking of automation, is fully automated (without any personnel involved) battery swapping one of the ongoing projects you are working on?

JV: I can say we have some ideas on this. It is a topic that needs addressing and discussing as automation is coming on all our equipment and all processes in the future.

Fully automated battery swapping testing is, of course, part of the roadmap.

IM: I also understand that your team originally came up with the MineGame tool for modelling battery-electric equipment fleets and infrastructure. What was this designed for?

JV: Yes, this is a tool we needed to develop to support fleet-wide electrification. It is not designed to recommend the type of machine you will get; it is more about how you implement the many electric machines in the mine, what impact this has on infrastructure, how many tonnes we can get out of different fleets, etc.

This modelling tool gives comfort to customers about the value proposition of fleet-wide electrification, while also showcasing how new, developing technologies can be implemented in greenfield and brownfield mines.

This tool – on top of those from Deswik and Polymathian within the Digital Mining Technologies division – will be a game changer for us.

IM: What about the interaction of manual and autonomous equipment? Is this something you are already testing at the Test Mine?

JV: This is an ongoing requirement from customers, who look to always alleviate production stoppages.

It is not an easy challenge to address though. Everyone knows we want to get safe systems in place with a mixed fleet as not all machines are currently automated.

There is obviously a value case for this, and the Test Mine is a good place to test it out.

All I can conclude with is to say we have many tests going on in the Test Mine…

IM: A cheeky question, I know…What will be the next concept vehicle? You’ve set yourself a big challenge with bringing one of these out every year. How are you keeping up with this?

JV: We have smaller concepts, and we have bigger concepts on the table. We need to ensure we develop the technology to get those concepts done in a timely manner and in a way that, as I keep saying, provides value.

Maybe the next one coming out will be one of those smaller concepts.

Then, of course, we have wild ideas for underground equipment further down the line.

IM: The Digital Mining Technologies division is becoming a much bigger part of SMR. Do you see a point where you will start using the day-to-day data coming off sensors on your machines to revamp existing machine designs and come up with new machines?

JV: Yes, this is mandatory for us to do at some point in time. Integrating data from the field and systems into the engineering process is a tried and tested policy in many industries – some of which Sandvik are serving – so we need to do that more in mining.

The big step I foresee on this front is when we truly understand the value of using artificial intelligence in mining. Leveraging these tools will ensure there is a continual optimisation loop that goes throughout our software, hardware and services.

Sandvik looks to shape the surface drilling electrification conversation

“We are showing what technology can do today.”

These were the words Mats Eriksson, President of Sandvik Mining and Rock Solutions, during the Capital Markets Day in Tampere, Finland, last week when describing the launch of Sandvik’s latest battery-electric concept surface drill rig.

This rig is representative of more than just technological advances in the mining industry, also acting as a tangible example of Sandvik’s efforts to become a leader in the surface drilling space.

It has been four years since Sandvik announced this ambition, with the company having made significant headway on achieving this goal.

Sandvik doubled its order intake for rotary drills from 2019 to 2022. Over this three-year period, the company launched the Leopard™ DI650i down-the-hole (DTH) drill rig to support fully autonomous drilling operations and went on to capture major autonomous drilling contracts in Latin America, Australia and Finland.

The OEM is looking to at least double its surface mining revenue from 2022 to 2028. Key contracts in 2023 from Boliden and MACA have already provided early positive momentum towards such a goal.

There is potential for Sandvik to steal a march on its competitors in this space – companies who have already been able to automate the largest blasthole drills in key markets in the Americas and Australia – by leveraging the electrification expertise it has built up underground.

This was highlighted by Eriksson last week and was reiterated further when IM spoke to the company’s experts in Tampere in front of the second battery-electric surface concept rig.

The concept vehicle is the first in its size class, capable of drilling DTH holes up to 229 mm in diameter and blending the autonomy of battery with the continuous endurance of power cable, Sandvik says.

Flexibility and optionality are the name of the game, with the rig equipped with a battery able to carry out seven hours of tramming or one hour of drilling based on Sandvik research, plus plug into electrical infrastructure with a  37-mm diameter, 180-m-long tethered cable.

Lauri Laihanen, Vice President, R&D, Surface Drilling Division, Sandvik Mining and Rock Solutions, told IM at the Sandvik Capital Markets Day event last week: “The main benefit of this battery-electric solution is the ability to tram independently for up to seven hours.

“When you need to move the rig after drilling a certain portion of the pit ahead of blasting, you can disconnect the cable and tram the rig away from the pit independently without worrying about managing the cable logistics. Then, when you have carried out the blasting and explosives loading process and are ready for the next drilling sequence, you can tram back without recharging in between.”

Petri Virrankoski, President of the Surface Drilling Division, added: “The application where these drills are used is somewhat different to rotary drills. To a degree, they are used in production drilling, but in a very dynamic way – carrying out pre-splits or blasthole patterns on smaller benches, for example.

“They need to manoeuvre around more, so there are more demands placed on them from a flexibility and cable management perspective.”

There are other potential benefits Laihanen talks up – the ability to carry on drilling or tramming during “black outs” and, on mine sites where cable-electric equipment is already used, connect the rig to the grid after diesel-electric blasthole drills and cable shovels have started up (to avoid power surges).

“For some of our frontrunner customers that have already adopted electrification on surface and have the infrastructure in place, they would only need to add one transformer to lower the voltage level from what their larger pieces of equipment are working off to start using this rig for drilling and tramming,” he added.

This type of talk – more practical than conceptual – is representative of Sandvik ‘making the shift’ when it comes to electrification in surface mining.

It has only been just over a year since the company unveiled its first electric concept rig, based off a much smaller top hammer drill rig meant for urban construction, but the understanding of what it may take to electrify these large rigs has grown tremendously.

“From a technology development and demonstration point of view, it is crucial to understand the framework that you have from the lower and upper end of the drilling portfolio,” Laihanen said. “This helps you track it with the customer base and finalise your productisation plan to hit that 2030 goal of having an electrified offering for the whole range.”

Eriksson says the company is confident in being able to offer electric surface drilling products across its range by 2030, with Sandvik’s continued advances in underground mine electrification spurring this on.

It is worth, therefore, noting some of the numbers that came out of the Capital Markets Day from the underground load and haul division.

Brian Huff, Vice President of New Technologies for the Load and Haul Division within Sandvik Mining and Rock Solutions, said the company had won more than 75% of the tenders it had been involved in from January-October this year, with more than 15% of the company’s load and haul order intake over this period representing battery-electric equipment.

One can also add sales of the company’s underground battery-electric drills, which started to be offered to the market from 2016, to these numbers.

The company’s Test Mine in Tampere, which IM visited last week, has played a key role in this growing Sandvik underground battery-electric population, and the recent announcement that Sandvik will look to replicate this on surface with the Sandvik Test Pit – some 40 km away – is another indicator of how serious the company is about becoming an open-pit drilling major.

Virrankoski explained: “If you look at the peak capabilities that have enabled us the successes underground, one of these is the Test Mine. This has been helpful for testing and developing not only the drill rigs, but also tooling, digital tools, automation, rock drills, etc.

“It became pretty clear about four years ago that we needed a similar capability for surface.”

This location just outside of Tampere was chosen due to the “good rock” availability, the ability to offer significant scale where the company could test out all boom and rotary drill rigs up to the DR413 class at the same time as providing customer showcases both on electrification and automation, the ability to cross-fertilise underground learnings from the existing Test Mine with surface drilling developments, and the continued development of existing and new Sandvik surface mining engineers.

The Sandvik Test Pit, which has previously served as a quarry, will be developed by its own drilling plan

The company already has multiple rigs, both boom and rotary, at the site – which is still being setup for testing – with the new electric concept rig expected to soon join it.

“The next action after that is to begin customer trials next year,” Laihanen said. “We have had preliminary discussions with several customers, but we need to finalise our own internal development testing before locking in these trials.”

This is indicative of the emphasis the company is placing on surface mining and the opportunity it has to shape the battery-electric conversation in the surface drilling space.

“For us, it is important to have a physical specimen to have these conversations with customers,” Laihanen said. “When you have something available, it makes the conversation around capabilities and limitations a lot easier, taking these discussions to a whole new level.”

Virrankoski added: “This will lead to a conversation around maintenance processes, the skills requirements, the service models, etc.

“Having a machine that can play in a real-life sandbox is very different to showing a model on a screen.”

Sandvik has laid its surface drilling marker down. The market will now decide if this is the direction it wants to move in.

Sandvik recognises OEM ‘first’ with AutoMine for Underground Drills introduction

Sandvik Mining and Rock Solutions is introducing AutoMine® for Underground Drills, a cutting-edge tele-remote solution that, it says, enables operators to remotely and simultaneously control and supervise multiple automated Sandvik underground drills, increasing efficiency, safety and overall productivity in mining operations.

With AutoMine for Underground Drills, Sandvik Mining and Rock Solutions has become the first OEM to introduce a unified traffic management system for drills, loaders and trucks, according to the company.

Jouni Koppanen, Product Line Manager, Underground Automation at Sandvik Mining and Rock Solutions, said: “Sandvik’s holistic approach to integrate drills, loaders and trucks into the AutoMine system will set a new standard for underground mining efficiency. AutoMine for Underground Drills is another milestone in our commitment to revolutionising out customers’ mining operations. This tele-remote system redefines underground drilling autonomy and safety standards.”

The new offering is available for Sandvik longhole drills (DL) series machines, offering three levels of teleremote operations: single drill, drill fleet and machine fleet. Operators have the flexibility to choose between operating from an AutoMine chair or console station, depending on which offering level best suits their operational requirements.

The AutoMine for Underground Drills teleremote system includes advanced tramming capabilities, allowing seamless control and coordination of drills, loaders and trucks operating in the same area with sophisticated traffic management, the company added.

Prioritising safety, AutoMine incorporates an enhanced Access Protector System. This safety feature is designed to prevent personnel from entering the machine area while the system is operating in automation mode or remote mode. In addition, it also has an advanced traffic management system that enables operators to easily control the traffic flow of multi-machine operations and handle complex operating situations, resulting in greater flexibility and mining output.

Sami Anttila, Product Manager, Longhole Production Drilling at Sandvik Mining and Rock Solutions, said: “We have developed this system to offer our customers a deeper integration and cooperation in between the underground drills, the loading and hauling machines and especially the AutoMine environment. This means added value through improvements in machine and fleet flexible utilisation in remote operation.”

Sandvik’s history of providing proven underground solutions with automation for loading and hauling dates back to 2004. Today, more than 1,000 underground and surface units operate worldwide at more than 100 customer sites, underlining Sandvik’s commitment to delivering reliable and innovative AutoMine solutions for mining.

Sandvik to explore surface drilling automation, digitalisation, electrification advances at new testing facility

In support of the shift towards electrification and the advancement of autonomous and optimisation technologies in surface drilling, Sandvik has acquired a new testing facility in Finland to develop and prove future surface drilling technologies.

The surface test mine is 40 km northwest of Tampere and Sandvik’s underground test mine. The area, which has previously served as a quarry, will be developed by its own drilling plan. The site is Sandvik’s first dedicated exclusively to surface drilling on such a large scale.

Petri Virrankoski, President, Surface Drilling at Sandvik Mining and Rock Solutions, said: “The development of comprehensive solutions that not only harness the latest technologies but also deliver productivity and reliability in our customers’ real-life applications and conditions requires a real-life test environment. The surface test mine will facilitate the exchange of our deep know-how in equipment manufacturing, rock tools, automation and digitalisation, supporting the design and development of even more new products and solutions in the future.”

Sandvik is currently developing the site, officially known as Sandvik Test Pit, and testing its first drills there. Over the next two years, the company plans to construct permanent office buildings and designated customer facilities at the location.

Sandvik will use the test mine for R&D as well as hosting customers for technology demonstrations, particularly those related to automation, digitalisation and electrification of surface drills. The site will enable technology development and training for both surface boom and rotary drill rigs, as well as rock tools, parts and services and related digital technologies such as automation and fleet telematics and monitoring solutions.

The test mine will also allow Sandvik to explore and demonstrate power source alternatives in a real-world environment, in which infrastructure to support both boom and rotary drilling electrification can be provided.

Dave Shellhammer, President, Rotary Drilling at Sandvik Mining and Rock Solutions, said: “Decarbonisation is accelerating across our industry, and the role of electrification in surface mining sustainability will help guide our development of new systems and solutions. Testing is a major part of our R&D cycle. This new test mine will help us shorten time to market and verify even more swiftly that we’re delivering the safest, most reliable and productive drill rigs to our customers.”

Thiess turning autonomous mining opportunities into reality

Thiess may have deliberately started small with autonomy, however, 10 years into its journey, the company is now being recognised as a mine automation leader in the ever-competitive mining services space.

Whether it is drilling, dozing or haulage, Thiess has plenty of autonomy expertise to offer.

The company started off in 2013 with maintenance and service work on the autonomous haulage fleet a major producer had assembled at its iron ore operation in the Pilbara. This has since broadened out to semi-autonomous tractor system (SATS) operations at major coal mines in Australia, autonomous drilling advances using Epiroc and Caterpillar platforms and, most recently, autonomous haulage and drilling operations at Pembroke Resources’ Olive Downs Complex greenfield operation in Queensland.

Trent Smith, Head of Autonomy and Operations Technology at Thiess, says the company seeks to involve itself early on with autonomy projects to ensure benefits can be realised.

He explains: “We like to help identify the opportunity for automation, which initially involves answering two big questions: is the application suitable? And does it deliver a financial benefit to the project? If there are positive answers to both questions, we try to work with those potential clients on how to bring the vision to life.”

Thiess’ involvement in this process is extensive, looking at network options, OEM selection, the “people element” and more, according to Smith.

“Our strategy was a bit different to others, where, aside from the work at our first autonomy project in the Pilbara, we started with small pilot projects on drills and dozers,” he told IM on the side lines of IMARC 2023 in Sydney earlier this month. “This enabled us to establish some solid foundations, understand the significance of the required changes, understand what the key enablers like networks were and put support models behind those aspects.”

To date, the mining services provider has worked closely with OEMs Epiroc and Caterpillar on modifying their autonomy platforms to fit its clients’ operations to improve safety and efficiency.

“With Caterpillar, we were able to take an emerging technology platform like Cat® MineStar™ Command for drilling and ensure it was fit for purpose for the coal environment we were planning to deploy it in.

“With Epiroc’s solution, we took a mature and proven product from the iron ore environment – equipped mainly for single pass, vertical drilling in competent ground with big and open drill pads – and tailored it for a coal application. This application required the introduction of autonomous rod changing and angle drilling for drilling in varied ground within tighter working areas.

“We worked hand-in-hand with Epiroc to understand the complexities of translating the solution for this environment, utilising all of the on-board data in the early trial stages and filtering that down to identify areas of waste and opportunity that could be used by the OEM and ourselves to realise an improvement in performance within that new environment.”

This evidently worked, with the companies, earlier this year, achieving the significant milestone of drilling more than one million lineal metres at the Lake Vermont coal mine in Queensland.

Pembroke Resources’ Olive Downs Complex has become the world’s first mining operation to deploy Command for hauling and Command for drilling solutions simultaneously

Thiess is also expecting to later this year reach the same autonomous drilling milestone with Cat’s Command for drilling platform; this time at a major coal mine in New South Wales.

The company has also helped achieve an industry first at Pembroke Resources’ Olive Downs Complex, with it becoming the world’s first mining operation to deploy Command for hauling and Command for drilling solutions simultaneously.

This assignment, which moved from concept to implementation of autonomous trucks and drills within a matter of 18 months, will ultimately include the deployment of 21 haul trucks (15 Cat 794 ACs and six Cat 793Fs) and three drills (Cat MD6310s) fitted with autonomous technology. Additionally, Thiess has established a private LTE network on Pembroke’s on-site communication infrastructure, enabling the safe operation of more than 85 connected assets within the autonomous operating zone. It has also upskilled more than 280 team members to, Thiess says, support the delivery of autonomous operations at Olive Downs to enable improvements in safety, operating hours, cycle efficiency and cost.

There is potential to add Command for dozing at Pembroke Resources’ Olive Downs Complex in future years, according to Smith.

“We have built the network and control room with the anticipation that this will be used,” he said. “We are already the first company in the world to have all three Caterpillar autonomy products running at operations, but Pembroke Resources’ Olive Downs Complex would be the first operation in the world to have all three Cat autonomy products operating at one mine.”

Thiess now has six autonomy projects out in the market, all of which are performing well against industry automation benchmarks, according to Smith, who says this capability is being recognised within the mining company community and OEM space.

The company has already announced its first automation project outside of Australia – at a coal mine in East Kalimantan, Indonesia, where it will deploy autonomous drilling operations – and Smith says the company is exploring further autonomous drilling opportunities in Latin America.

As well as continuing to engage with the wider OEM market on automation options, Thiess is working on different automation applications for existing products.

“With the SATS Command for dozing product, for instance, we are looking to take the platform and work with Caterpillar to move it towards a rehabilitation application,” Smith said, referencing the Thiess Rehabilitation business the company launched last year. “The requirements in mine rehabilitation are somewhat different to standard dozer push and stockpile applications, with multi-push vectors and the ability to potentially control several small-scale projects from one centralised hub.

“This is an example of where we work with an OEM, bring our knowledge of working with the product, identify a new application for the product, and then lay out what new set of capabilities need to be addressed to meet the requirements and fulfil that market opportunity.”

The company has a track record of proposing and advancing such autonomous dozing opportunities in certain niche applications, Smith said, adding that it recently achieved the 10 million cubic metres push mark with SATS.

The first rehabilitation application for SATS could end up being at a project in central Queensland – a project the Thiess Rehabilitation team started work on last year.

Against this advancing autonomy backdrop, Smith says the company continues to be asked about combining the “decarbonisation” and autonomy pieces of the mine operating puzzle, with a staged approach typically being recommended.

“At the moment, these two (autonomy and decarbonisation) are a little bit separate, but they will converge at some point,” he said. “I imagine artificial intelligence and predictive capabilities will play a role in that – evaluating when the truck might run out of charge, when is best to pull that truck out of service for a 30-minute fast charge, etc.

“What I would say is if you have taken a step in either direction (autonomy or decarbonisation) already, you are well placed for this convergence.”

Smith offered up one last piece of advice to any company looking to take its next automation step: “Don’t forget the people and process part.”

He explained: “Most organisations know how to deliver a technology project, but I think the real value in automation is bringing the people and process along with that. Automation is a business transformation.

“We worked with Pembroke Resources’ at their Olive Downs Complex to ensure the appropriate change management process to enable automation was implemented across all business functions. Each function was reviewed to understand what needed to change to bring in automation and create a cohesive environment.

“It’s already starting to pay off at that project, where we exceeded our target of 6,500 annualised hours within two months of commencing autonomous haulage operations.”

Mark Norwell on the Perenti mining services differentiator

Perenti continues to make inroads across the mining value chain, reflected of late with the recent acquisition of DDH1, record 2023 financial year results and deployment of some of its initial artificial intelligence-backed solutions from the idoba technology business.

Against this busy backdrop and a keynote address at IMARC in Sydney, IM caught up with Mark Norwell, Managing Director & CEO of Perenti, to talk technology in the mining services space.

IM: The contract mining and mining services business is a very competitive space (especially in Australia). How are you readily leveraging technology for your mining clients as a competitive advantage?

MN: The industry has always been competitive, and that global competition continues to evolve.

I would say Barminco has been at the top of the game for three decades. Having that technical competence, the process, the scale and the people drives competitive advantage in its own right. As we have seen some shift in technology and new technology initiatives, the adoption has added to productivity and, therefore, our competitive advantage has grown again.

In terms of how we are adopting technology, there are a couple of areas to mention.

To come back to Barminco, one aspect has been through deploying point solutions for productivity improvement. This has been ongoing and part of our DNA.

More broadly, when we launched the idoba technology division a few years ago, we took the view that as we see greater shifts and acceleration of technology opportunities in mining, we needed the internal capability to drive that change from the inside out; not from the outside in.

We have the deep domain expertise in mining that, when combined with our technology business, further improves our existing contracting services, as well as creates new potential lines of business.

The differentiator for idoba is the ability to develop products and trial them within our own captive ‘sandpit’. A lot of technology companies don’t have this option. They develop solutions and go to mining companies with a great idea that lacks the evidence of trial data needed for many mining companies to implement the solutions. As a result, the trials never get off the ground. We don’t have that problem given we have operations – and supporting clients with matching values – to allow us to trial products in the field. This has been witnessed of late where we are rolling out some products to test across our underground mines in Australia (idoba recently announced that its Mine Performance Navigator AI-powered decision-support and analysis tool had been rolled out to a dozen underground Barminco-operated mine sites).

IM: In terms of automation, digitalisation/digitisation and electrification, where are you looking to take the lead for your mining clients?

MN: They are all interconnected to some extent. Digitisation, for example, really drives the value from deploying automation and electrification. That digital platform is imperative for mines of the future and is where idoba comes into play.

We want to be at the forefront with digitisation and the digital platform; likewise with electrification.

With our Barminco business, we are one of the world leaders in hard-rock underground mining, and electrification just makes sense for underground hard-rock mines – there are so many benefits. What’s also important is the collaboration associated with that. We heard this week from Perenti, ABB and IGO on the IMARC panel discussion that no-one has all of the capabilities to effectively electrify a mine, so choosing partners is crucial to execution.

Under an agreement between mine owner AngloGold Ashanti, Barminco and Sandvik, the Sunrise Dam gold operation in Western Australia began trialing the prototype 65 t Sandvik TH665B on September 14

When it comes to automation, it is an area we are working through. We have established teleremote and remote operating centres in the recent past – operating multiple machines at remote mine sites from Perth, for example – but, at this stage, we are not accelerating these developments at the same pace as electrification and digitisation due to timing really being of the essence for these two.

Saying that, our work with Sandvik and Newtrax on Level 9 collision intervention is related to this, being a building block of automation more broadly as well as a major game changer from the safety perspective. Once we nail that with a digital platform, we will continue to advance automation more broadly. We are closing in on that with Level 9 collision intervention trials expected to take place in the near term.

When we look at idoba and the work we are doing on DiiMOS (Distributed, Intelligent, Integrated Mining Operating System), we are agnostic to the equipment, the mine planning software and the broader mining processes at play. If we are not agnostic, we could end up locking our clients into one route that potentially ends up destroying value. We are also building out a capability where some clients can pick and choose, or take the full suite, from idoba.

The focus is on providing solutions bespoke to the mine’s needs.

IM: How are you balancing your close relationships with the technology vendors and your own internal technology developments through idoba? Who are the most obvious first customers for the idoba platform?

MN: There is always going to be some overlap and crossover, but we come at this with an operator mindset, where technology can augment this. The OEMs come at it from an equipment mindset with associated technologies to bolt on. The combination and partnership of these two approaches makes sense as you have the equipment, technology and operations covered.

There will be areas where we still have some competition but, ultimately, it is limited.

The full value is going to be generated through how we partner and collaborate with all the companies within the value chain. We have a long history of collaborating with Sandvik, for instance, as well as recent history with ABB, and everyone brings something different to the table. Without that combination of capabilities, we are not going to see the industry shift at the rate it needs to.

Our starting point for idoba will be servicing our current customers as we develop new products and support them on their journey. We will see some clients want more of our solutions than others. As we service our current clients with these, we can take what we have learnt to service new clients. The new clients might be mine operators themselves, where we provide digital solutions as a software-as-a-service. This opens up new potential markets to us, which goes to the broader strategy we set in 2019. This recognises the deep domain expertise we have in mining – which has served us extremely well and is not something everyone has. The plan back then was to leverage this and build out the services beyond that current offering; technology being one of those.

As we develop this new technology, we have learnt that we have the ability to offer lower capital intensity solutions that can serve us well throughout the mining cycles.

IM: Looking at decarbonisation and, more specifically, the agreement you have in place with ABB to ‘reduce the risk and uncertainty of electrifying both green and brownfield operations’; could you talk me through what risk mitigation processes you will be using as part of this? How do you tackle the uncertainty associated with making investments in infrastructure, people and technology against a very ‘fluid’ technology backdrop?

MN: There are a couple of areas that need to be front and centre through that journey. The digital integration platform is one of those – the complexity of what we’re solving for these days is far greater than what we were used to. Whether you are putting in a point solution, or a whole mine to electrify, having a digital platform is critical to making the right decisions at the right time.

As the technology evolves, this digital platform is even more integral to reinforcing decision making. If you go straight to the hardware without the digital backbone and the distributed network of energy needed to electrify, you are setup to fail in the long term.

The other aspect that needs consideration from a risk mitigation perspective is having the leadership and culture in place to see these projects through. Leaders have to be ready to unlearn and relearn throughout this process.

Not only that you need to try to engineer out risk wherever possible through critical trials, a strong operational methodology and an assessment of the causal factors of what can go wrong and where those points are within the design. This could be through a traditional engineering methodology or technology adoption.

IM: You set up the Denver office a few years ago now. Outside of Hemlo and Red Chris, what does the pipeline of opportunities look like in North America? Does this client base require a different type of offering to what you traditionally have in Australia?

MN: We’re currently about A$100 million ($64 million) of revenue between those two agreements. We are looking for that to grow to A$400-500 million over the next three to four years. We see the pipeline in Canada and the US as significant. We have also installed the former head of AUMS in this business, looking to replicate the success we had in Africa over eight years in North America.

It’s fair to say the contractor model for Barminco is well understood in Australia and Africa; more so than in North America. In North America, they have a contract model that tends to be based on a charge-by-the-hour type of agreements, whereas we are looking to bring a technical approach to all our contracting.

At the same time as looking to grow this business, we are conscious of growing too quickly. Bringing in a new mining methodology takes a lot of change management. We don’t want to go too quick and have a misstep.

IM: What about ongoing M&A? Are there still gaps in the portfolio you are looking to fill?

MN: In terms of our strategy, we have said we will continue to build our portfolio to leverage our core competency in mining and adjacent areas to add value. We ultimately want a complete portfolio of businesses that have adjacencies to our core businesses.

We are still open to further M&A as long as it leverages our core capabilities and makes sense to our investors.

BME promotes smart, safe technology for loading blast holes

The productivity and safety of BME’s mobile manufacturing units (MMUs) is enhanced by smart technology, making real-time data available on the loading of bulk emulsion into blast holes, the company says.

Smart MMUs are a key aspect of BME’s automation efforts, which leverage machine learning and artificial intelligence. The company’s digital solutions, such as Xplolog and Xplocharge, can automate aspects of blast hole charging, including the real-time tracking of emulsion volumes being pumped on the bench by smart trucks.

“These volumes are monitored by on-vehicle equipment, which compares the planned volumes with the actual volumes required,” Nishen Hariparsad, BME General Manager of Technology and Marketing, explained. “This data can then be transmitted wirelessly to be stored and analysed in cloud platforms.”

The data lends itself to ongoing cost optimisation, and to ensuring that there is no wastage of resources in achieving the optimal blast result. Truck performance can also be measured by digital telemetry through internet of things devices. This functionality improves productivity, maintenance control, product quality and asset use. The safe and smart loading technology of BME’s MMU’s is made possible at its specialised in-house assembly and fabrication facility in South Africa, where BME has built more than 200 MMUs.

The company is constantly evolving and improving its smart technology, and recently released a new version of its Xplolog system for capturing and analysing data on blast holes and decks. The performance of this version is enhanced with design and application code built from the ground up, and with a new and upgraded database using Google’s Cloud Services.

The installation of this technology on MMUs helps mines to monitor their block progress in real time and allows the quality of blasts to be continuously improved to provide sustainable outcomes for BME’s customers, the company says. Together with BMEs digitally smart MMUs and loading solution, a seamless integration of on-bench digital technology and electronic initiation systems also make an important contribution to controlled blasting, which prevents risks like vibration and fly-rock, further preventing poor blast outcomes, it added.

Epiroc registers robust mining demand in Q3

Epiroc continued to register high demand from the mining sector in the September quarter, as several large mining equipment orders were won over the three-month period, leading to a 17% year-on-year rise in orders received.

This total of SEK14.36 billion (US$1.29 billion) was supported by strong organic growth and acquisitions, Epiroc said, as well as its largest order ever received – a SEK700 million agreement to supply the Kamoa-Kakula copper operation in the DRC with Minetruck MT65 S haulers, Scooptram ST18 S loaders, Boomer 282 face drilling rigs and Simba E70 S production drilling rigs.

In a quarter that included no acquisitions, Epiroc saw its operating profit increase 12% to SEK3.26 billion, while its operating margin was up at 21.7%.

Helena Hedblom, President and CEO of the company, said the quarter saw particularly strong demand for its automation and connectivity solutions, which was reinforced by a recent agreement with Boliden, Algoryx and Örebro University to evaluate autonomous face drilling options, plus a separate strengthened cooperation with Newcrest Mining to take a holistic approach towards the entire mining process at several Newcrest mines.

Outside of these financial specifics, Hedblom said the company was also looking to consolidate several functions – transactional and human resources, among them – into new regional centres of excellence to better serve customers in certain markets as part of its wider operational excellence pursuit.

“These will be rolled out region by region,” she told IM.

One such change is happening in South Africa, with the company moving production of its low-profile machines from Örebro, Sweden, to South Africa. This move follows the acquisition of Aard Mining Equipment in April of this year, and recognition of a substantial portion of the low-profile market being in southern Africa, Hedblom acknowledged.

Aard, based in Chamdor near Johannesburg, designs, manufactures, services and supports a wide range of mining equipment, specialising in low-profile underground machines for mines with low mining heights. Its products include drill rigs, bolters, loaders, scalers, and more.

BEV retrofits on the up

A key differentiator in the Epiroc electrification portfolio that has been covered extensively by IM is the company’s battery-electric retrofit options.

Launched in the March quarter of 2021 – with the first retrofit kit offered for the ST1030 underground loader – the solution was viewed as a sustainable way to electrify machinery, with the conversion kits expected to be fitted during a midlife service rebuild.

Hedblom said interest for these retrofits continued to build from the mining community, with the company scaling up the number of retrofit kit models available, the expertise and resources to enact these changes, and the “standard operating procedures” required to offer this.

“It is still early days…but over the coming years we expect to have a mix of both new [battery-electric] equipment sales and retrofits coming through,” she said.
