The industry has been told continuously that there are plenty of synergies between automation and electrification when it comes to loading and haulage, yet the hard evidence of this complementary nature has not yet surfaced. That could be about to change if a trial at Vale’s Creighton mine in Sudbury, Ontario, proves successful.

Vale has been a key electrification partner for mining OEMs and service providers, testing out a whole host of battery-electric equipment from light utility vehicles to 42-t-payload trucks at its deep mines in Sudbury. This builds on its experience of running diesel-electric Kiruna trucks since the mid-1990s at the Coleman mine (also in Sudbury).

The miner has also commenced trials on surface with battery-electric trucks and is set to commence trolley assist operations at its massive Carajas iron ore mining complex in Minas Gerais, Brazil, later this year.

The variety of testing the company has carried out – in terms of the types of mining operations, vehicle setups, charging methods and electrical infrastructure – means it can be considered an electrification pioneer.

Now, it is looking to combine this experience with its knowledge of autonomous loading operations – again an area of the technology space it is considered a leader in.

In partnership with Epiroc, a battery-electric and automation project is in the planning stages at Vale’s Creighton underground mine.

The two companies commissioned four Epiroc ST14 Battery Scooptram and two MT42 Battery trucks at the operation in preparation for the deepening of the mine in the December quarter of 2022. Full-scale operation is ramping up with a first charging bay already commissioned and new ones coming in the next months, a Vale spokesperson told IM.

“The next steps will be to leverage the autonomous capability of those battery-electric scoops to enable operations between shifts depending on the application at the mine,” the spokesperson said.

Vale has previously said it will transition to an all-electric fleet at Creighton as part of its plans to develop the orebody down to circa-3km below surface.

Epiroc achieves major open-pit autonomous drilling milestone with Pit Vipers

Epiroc says it continues to accelerate the transformation of the mining industry toward lower emissions, strengthened safety and higher productivity with its autonomous drill rigs having achieved another milestone in successfully drilling the equivalent length of more than once around the world.

The company’s drill rigs, used by mining and construction customers across the world, are increasingly operated autonomously. The company’s Pit Viper surface drill rigs have now drilled holes totalling more than 41 million metres, exceeding the world’s circumference of 40.1 million metres.

The societal benefits generated so far are significant, including a reduction in CO2e emissions of more than 100 000 t. An equivalent in effect would be to plant a new forest the size of the Swedish capital, according to Epiroc. The reduction in CO2e emissions is achieved through increased efficiency of autonomous drilling, higher-precision drilling and a significantly reduced need for travel to the rigs, which can be at a far distance from the control room.

Similarly, Epiroc’s autonomous underground rigs, such as the Simba production drill rigs, are increasingly used by customers. One of Epiroc’s mining customers has drilled more than a million metres autonomously underground using a single Simba rig.

In addition to lower emissions, other benefits of autonomous drilling include a safer and more comfortable work environment for operators, and higher productivity.

“Our autonomous drilling solutions are one example of how we are accelerating the transformation toward a more sustainable future,” Helena Hedblom, Epiroc’s President and CEO, says. “We have a rigorous innovation agenda, also within digitalisation and electrification, to find new ways to reduce the environmental impact, while increasing safety and productivity.”

Epiroc says it has launched several initiatives to support the industry to extract the needed minerals in the most sustainable and efficient way possible. For example, it is working toward offering its complete fleet of underground mining equipment in emission-free versions by 2025, and its full fleet of surface equipment in emission-free versions by 2030. Another example is the partnership with steelmaker SSAB that began in 2022 to produce mining equipment using fossil-free steel.

Epiroc also supports the transition towards a circular economy by providing equipment and services that enable the recycling and reuse of materials. For example, Epiroc’s hydraulic attachments tools are used by the construction industry to process concrete, asphalt and other materials on site, reducing waste and improving resource efficiency.

In 2021, Epiroc received validation from the Science Based Targets initiative (SBTi) for the 2030 targets to halve its CO2e emissions in own operations as well as from the use of sold products. The SBTi validated Epiroc’s climate targets as being in line with keeping global warming at a maximum 1.5°C, consistent with the latest climate science and the goal of the Paris Climate Agreement.

Anglo Asian Mining says it has placed orders for the major items of equipment required for production from its new Zafar and Gilar mines in Azerbaijan, with a fleet made up of Epiroc drills, Caterpillar loaders and auxiliary machines from the likes of Paus and Tunelmak.

The company has also made progress with the upgrades to its Gedabek flotation plant, it noted.

The equipment for Zafar and Gilar includes an underground fleet from Caterpillar and drilling machinery from Epiroc. The total equipment cost is approximately $10 million, approximately 40% of which will be met from the company’s existing cash reserves with the remaining being funded through vendor financing. The equipment is a significant investment for the company, underpinning its confidence to achieve its stated ambition to transition to mid-tier copper production status, it said.

A day before this announcement, Anglo Asian said it had completed a scoping study for the Zafar underground mine, based on ore production of 700,000 t/y and a 0.5% copper equivalent cutoff grade. Development work and the construction of two portals has also started.

Included in the drilling fleet is an Epiroc Boomer S1 D, three Epiroc T1D jumbos, one Epiroc Simba S7 D and one Epiroc H1354. The Caterpillar machinery includes three 15-t payload R1700 LHDs and two UMA 980 wheel loaders.

Auxiliary units that will complement this fleet include a Paus TSL853 Central articulated steering telescopic swivel loader, two Tunelmak ADROIT 520-2 AH 4×4 hydrostatic basket platforms and one Tunelmak ADROIT 420AH 4×4 articulated hydrostatic shotcrete pump.

Anglo Asian produced 57,618 oz of gold equivalent for the year ended December 31, 2022, but, with the addition of Zafar and Gilar, it has an ambition to become a mid-tier miner producing over 100,000 oz/y of gold equivalent.

An expansion of the flotation plant at Gedabek, the company’s flagship opeation, is underway together with adding a further line to produce zinc concentrate, it said. The total cost of the expansion, which will see it add three new rougher/scavenger cells and four cleaner cells from Maelgwyn Mineral Services, is currently estimated at $3 million which will be paid from the company’s existing cash resources. Contractors have been appointed to supply materials for the new flotation line. Additional contractors will be commissioned to modify the existing building and provide electrical services and control equipment, it added.

The modifications to the flotation plant to increase its capacity have now been broadly completed. The installation of the new flotation line using hydraulic flotation cells will be completed by the end of the year.

Stephen Westhead, Vice President of Anglo Asian, said: “The new equipment will be used to expand the company’s mining and processing operations with the development of two new underground mines this year. The expansion of our flotation plant has been broadly completed, doubling capacity and creating additional processing flexibility. This represents an important step in our medium-term growth ambition to become a mid-tier production miner, and significantly increases our capabilities within copper.”

In conjunction with the recent announcement from Roy Hill on its planned expansion of autonomous haul trucks using ASI Mining’s Mobius based autonomous haulage system (AHS) combined with Epiroc support, ASI Mining is announcing full commercialisation of its AHS program.

The Product Verification Phase at Roy Hill included the operation of a mixed fleet of CAT 793F and Hitachi EH-5000 haul trucks operating under ASI Mining’s Mobius traffic management system (TMS). Full integration with Wenco, the fleet management system (FMS) used by Roy Hill, is also underway as part of ASI Mining’s interoperability with fleet management systems.

The phase included key performance indicator verification of efficiency, productivity and AHS availability using a fleet of 10 haul trucks operating in both ore and waste hauls at multiple locations within the Roy Hill iron ore mine.

With the validation phase complete, Roy Hill will move into the expansion phase to convert and operate the different truck models under Mobius representing a total fleet size of 96 haul trucks, making it the largest AHS site in the world, acoording to ASI.

Successful completion of this verification phase has enabled ASI Mining to fully validate the overall performance capability and operational safety of its system and establish the full level of related field services for deployment and support of its AHS product, it said. Support of ASI Mining’s AHS globally will be through Epiroc’s distribution network, such as the one based in Perth Australia, supporting the Roy Hill deployment.

While Mobius supports AHS operations, it is an autonomous mining platform supporting other applications such as Mobius for Blasting, Mobius for Drills, Mobius for Dozers, etc.

The Roy Hill AHS project will focus on safe and highly productive operations and will leverage ASI’s Mobius to achieve an integration platform which can continue to scale for future applications, it said. The commercialisation of AHS will now also enable bringing these other autonomous applications to market.

OZ Minerals navigating Carrapateena mine traffic issues with Mobilaris solutions

OZ Minerals, through the implementation of Mobilaris Situational Awareness and Mobilaris Onboard, has improved traffic flows at its Carrapateena copper-gold mine in South Australia, according to a recent case study.

Having implemented the solutions from Mobilaris, owned by Epiroc, the mining company gained a better understanding of where machines and people were physically located underground – and operations became safer.

Since commencing production in December 2019, the Carrapateena mine has become, over the past decade, one of the biggest mining projects in the state. The ore must be hauled from the production levels to the crusher level via a short decline with limited passing areas, which poses challenges.

To optimise haulage flows, OZ Minerals deployed Epiroc’s Mobilaris Mining Intelligence decision support system to digitise the mine.

Daniel Bruce, Superintendent, OZ Minerals Carrapateena, said: “We saw potential to remove some of the constraints we have underground. You can’t see around corners, and you can’t see through rock, so understanding where things are – where people and machines are – is a lot more difficult than in a typical workplace on the surface.”

OZ Minerals rolled out the first feature in 2019: Mobilaris Situational Awareness, a solution for surface control room operators. Mobilaris Onboard, a solution for underground operators in vehicles, followed in 2021. Thanks to real-time 3D visualisation, anybody with access to a tablet or a PC can quickly understand where machines are operating, according to Epiroc.

“Mobilaris Situational Awareness allows you to see, live, at any point in time, where all the equipment and people are in the mine,” Bruce said. “It also allows you to navigate to locations, equipment and refuge chambers.”

OZ Minerals had initially installed Wi-Fi tags on all its vehicles, which provided accuracy to around 150 m. With Mobilaris Onboard, it can achieve location accuracy of 5-10 m without any extra infrastructure, and all that is needed are basic OBD2 adapters or a Doppler radar, Epiroc says. Implementation started with trucks and loaders, and now the entire underground fleet has been equipped.

This has significantly improved real-time position information, according to Amelia Schmidt, Senior Technician in the site operations team at Carrapateena.

“Everyone at the site operations centre – dispatchers, mine controllers and haulage control – is now using Mobilaris Situational Awareness,” she said. “Previously, it could take quite a bit of time to search for a piece of equipment, but it only takes seconds now to see its last location.”

The system also helps OZ Minerals with its fleet management – to determine where trucks are, for instance – thus becoming a tool in the decision-making process.

Schmidt said: “For those who are perhaps new to the mine, we’ve been able to insert points of interest on the map, for example where it is best to hold. Cycle times are well managed, despite underground operations becoming a lot busier.”

OZ Minerals then implemented a second Mobilaris feature: Mobilaris Onboard, a tablet in a vehicle that acts just like a car navigator but without any need for a dedicated tracking infrastructure. This provided everyone underground with a tool that enabled them to easily understand how equipment was positioned around them.

Bruce added: “This is another piece of information that the operator can use to make a decision – and all of these minute decisions add up to a more productive and safer workplace.”

For Carrapateena Truck Captain, Joel Dodd, everyday work has become easier thanks to Mobilaris Onboard.

“One of the main benefits is that we’re able to travel down and get to our locations a lot better,” he said.

OZ Minerals now has around 200 tablets in vehicles underground – in trucks, LHDs, face drill rigs and light vehicles – and the feedback has been very positive.

“When people can see more clearly where other people are, it helps them avoid unwanted interaction,” Bruce said.

RCT helps automate dozer push operations at New South Wales tailings op

Automation, Mining equipment, Mining safety, Mining services, , , , , , ,

A well-known mine in New South Wales, Australia, is now operating an autonomous dozer fleet safely and efficiently thanks to the deployment of RCT’s latest solutions, the METS company says.

The technology empowers equipment operators to stand at a safe vantage point overlooking the work zone and direct the dozer fleet to maintain a tailings dam wall on site.

The project means the autonomous dozers can push the top of the tailings dam wall and work close to edges in a way deemed as impossible to achieve safely with operators in the machine’s cab.

Mine management selected RCT’s ControlMaster® solution over global OEM tenders due to the technology’s ability to be repurposed to other mining equipment based on changing fleet demands in the future, RCT, now owned by Epiroc, said.

RCT’s Customer Service team recently mobilised to the site and commissioned ControlMaster onto two Cat D8T dozers and are continuing to support the site on an ongoing basis.

RCT Account Manager, Wayne Carrington, said the project is just the latest in a successful business relationship with the mine which stretches back many years.

“We are very pleased to provide the site with fit-for-purpose technology which safeguards their personnel while enabling them to complete vital works,” he said. “The feedback from site has been very positive with the operators loving the functionality of the solution and management is reporting that they are meeting their targets.

“The ControlMaster technology is vital to the success of this tailings dam project but, in the future, the solution can easily be integrated with any other piece of mining equipment and provide additional benefits to the mine.”

Epiroc spots further agnostic automation opportunities

Having convinced iron ore miner Roy Hill to move ahead with plans to create the world’s largest autonomous mine, Epiroc and ASI – which the OEM owns 34% of – are ready to take on new equipment-agnostic automation opportunities, Helena Hedblom says.

Speaking after the company’s December quarter and 2022 results were released, Hedblom, President and CEO of Epiroc, said the company and ASI had progressed through three years of rigorous testing of the system, with the solution now entering the “scale” phase.

The Roy Hill project’s Production Verification phase was recently completed with 10 converted haul trucks fitted with vehicle automation kits and in cab clients using ASI Mining’s Mobius traffic management and on–board automation systems to navigate the mine’s virtual map, communicating with ancillary vehicles and the control room.

From March, the companies will start converting the mixed fleet of 96 conventional haul trucks to driverless operation, which is an increase from the 77 trucks originally set to be converted to running autonomously.

“There are certainly opportunities to deploy such solutions elsewhere,” Hedblom told IM. “If you look at how we started autonomous drilling with BHP, we took a step-by-step approach ahead of rolling that out to our customer base.

“We and ASI hope to be able to do that for this type of autonomous haulage solution too.”

Epiroc’s financial results highlighted another robust quarter where orders received increased 18% year-on-year to SEK13.7 billion ($1.3 billion), representing an organic decrease of 4% and organic growth of 3% when excluding Epiroc’s Russian business (which has now ceased). Revenues increased 25% to SEK13.9 billion, an organic increase of 8%, and operating profit increased 25% to SEK3.2 billion.

While this quarter saw fewer large orders than previous three-month periods, it did see the easing of supply challenges and good output levels, Epiroc said, adding that operating profit was at a record high.

The period also saw the company complete the acquisition of four companies – Remote Control Technologies (RCT), Wain-Roy, Radlink and Geoscan – continuing the acceleration of M&A activity Epiroc has become known for.

The purchase of RCT also offers another automation in-road, with the Australia-based company known as an OEM-agnostic automation specialist.

Listing off several of these acquisitions, Hedblom also highlighted the planned acquisition of CR, which has an offering covering surface and underground mining, and products including cast lips, teeth, and protective shrouds installed on mining buckets and loaders.

“CR and ground engaging tools represent a new niche for us,” she said.

When Epiroc announced the planned acquisition in December, it said the move was predicated on expanding its “first-rate offering” of essential consumables and digital solutions.

Hedblom, meanwhile, said the company would continue to evaluate further M&A opportunities as they appeared.

Outside of automation and digitalisation, Hedblom remained confident the company would hit its electrification goals in 2025 – goals that include offering a complete range of emission-free underground products.

“We actually had our first order for the underground tunnelling sector recently,” she said. “We are very well positioned to achieve these targets.”

Epiroc reinforces down-the-hole drill bits with new productivity tools

Equipment maintenance, Mining consumables, Mining equipment, Mining services, , , , , , , , ,

The launch of Epiroc DTH drill bits, Epiroc says, signals a new era for down-the-hole drilling, with increased productivity and profitability.

Thanks to a new design and the use of the new Epiroc carbide, these drill bits will last up to 20% longer compared with an older version of the company’s drill bits, according to the company.

An all-new face design results in optimised flushing and handling of drill cuttings, while the addition of more buttons on the drill bits increases the overall energy when drilling, Epiroc says.

There are also three different button shapes to choose from to tackle different drilling needs and types of rock: Epiroc Trubbnos, spherical and ballistic buttons.

On top of the new carbide inclusion, these DTH drill bits are produced with improved heat treatment and increased face hardness, resulting in a more durable, sturdier and robust bit, with increased service life, it added.

Fredrik Gransell, Global Product Portfolio Manager at Epiroc Rock Drilling Tools, said: “If we add up the new design features and the improved materials usage, it’s safe to say that Epiroc DTH drill bits will last up to 20% longer compared to an older version of our drill bits.”

Delaney Erickson, Global Product Manager DTH at Epiroc Rock Drilling Tools, added: “You can expect more drilled metres per shift from high-performing Epiroc bits, which is good for both your revenue and profitability.”

Longer service life also means fewer interruptions and more undisturbed drilling, one of the most sought-after improvements, Epiroc says. “Put simply, with less time spent lifting and changing heavy bits, workdays will not just be more productive, they will be more convenient too,” the company added.

Finally, Epiroc DTH drill bits reduce the customers’ footprints as they can drill more and still use fewer bits. As a result, less energy and raw materials are used to produce bits, with less waste and associated transportation.

LKAB is further increasing its safety capabilities by implementing several solutions from the Mobilaris Mining Intelligence platform at its Kiruna mine in northern Sweden, Epiroc says.

The platform, now 100% incorporated into Epiroc following the consolidation of its ownership in Mobilaris MCE AB in 2021, allows all employees to receive alarm and crisis information and confirm directly on their mobile phones in an emergency situation, Epiroc says. Employees can also obtain position support and the ability to navigate faster to rescue chambers with the help of applications on their mobile phones.

This means rescue personnel will now have the tools and means to manage emergencies better and faster, according to the OEM.

Joel Kangas, LKAB’s Kiruna Mine Manager, said: “We want to shorten the time from when an alarm goes off to when everyone is safe, and we believe this digital solution can help us with that.”

Hans Wahlquist, Global Director of Product Management at Epiroc, said: “LKAB already has a high level of safety, but now there are new technologies and new opportunities, and they have the infrastructure required for this installation. This project will give everyone in the mine more information about the situation in real time.”

LKAB is setting a new world standard for mining where digitalisation forms an important step towards easier, safer and more efficient work in the mine. The mobile safety solution project is a collaboration between LKAB and Epiroc, involving both existing products from Epiroc and new developments. The project began in the autumn of 2022 and the goal is to start rolling out the solution in the spring of 2023 at the Kiruna mine.

Andreas Ericson, General Manager Epiroc Mining Intelligence, said: “Collaborations with customers are crucial for finding innovative solutions. This project demonstrates the potential for digital transformation in the mining industry, bringing us one step closer to a smarter and more efficient future.”

The following four modules from the Mobilaris Mining Intelligence portfolio are included within the project:

  • Location of people with the ability to receive alarm and crisis messages on their mobile phones through Mobilaris Situational Awareness and Mobilaris Virtual Tag;
  • Distribution of emergency messages and support provision for getting people to safety through Mobilaris Emergency Support;
  • Three dimensional map in vehicles for navigation assistance, increased traffic safety and the ability to quickly find the nearest rescue chamber through Mobilaris Onboard; and
  • Three dimensional map on the employee’s mobile phone for navigation assistance and the ability to quickly find the nearest rescue chamber through Mobilaris PocketMine.

Orica, Epiroc and Agnico Eagle carry out world-first development charging milestone at Kittilä

Orica and Epiroc, in partnership with Agnico Eagle Mines Limited, have successfully commenced live blasting with Avatel™ – the world’s first semi-automated wireless underground development charging solution at Agnico Eagle’s Kittilä mine in Finland.

The milestone brings to life an industry-driven concept that dramatically improves safety at the face, which is one of the highest risk activities in underground mining today, Orica and Epiroc say.

Avatel enables a single operator to prepare and wirelessly complete a full charging cycle from the safety of an enclosed cabin while offering the best available blast outcomes through the integration of Orica and Epiroc’s flagship digital, automation and blasting technologies.

The first successful blast was loaded and fired on November 22, 2022, comprising 61 Orica WebGen™ 200 Dev wireless primers and 295 kilograms of Orica’s Subtek™ bulk emulsion loaded to a development face at the Kittilä mine.

Orica Chief Technology Officer, Angus Melbourne, said: “Together with Epiroc and Agnico Eagle we are extremely proud of the team in creating a solution that keeps people out of harm’s way during what is considered one of the highest risk activities for underground miners around the globe.

“With Avatel, we can now effectively manage risk for the people who spend the most time every shift directly exposed to hazards at the development face while delivering all of the blast optimisation benefits that Orica’s flagship technologies bring. The combination of digital, automation and wireless blasting technologies and by partnering with customers and peers, we can continue to solve the industry’s biggest challenges across safety, productivity and sustainability, together.”

Sami Niiranen, President for Epiroc’s Underground division, said: “This is a true milestone achieved for our industry where Epiroc in partnership with Orica have led the way to safer underground operation. By building on our recognised solutions and advanced Rig Control System, Avatel paves the way to safe productivity for the mining industry.”

Jari Näsi, Development Manager – Kittilä Mine, Agnico Eagle, said: “We are proud to create history here at Kittilä where the first mechanised and wireless development blast was initiated. There is always some risk when working close to the face; being able to do this work safely and efficiently from the cabin is promising, and mechanising the process will give a better blasting result.”

The first commercial implementation of Avatel will take place at Newcrest’s Cadia Valley Operations from December 2022.
