Cisco IoT solution underwrites Boliden automation transition at Garpenberg

Cisco says it has helped Sandvik and Boliden deliver a safe, autonomous and efficient operation at the miner’s Garpenberg underground mine in northern Sweden.

The IoT solutions provider has installed a low latency IoT network with Cisco industrial switches and access points in the mine, which is more than 1 km underground, to facilitate this transition.

As Cisco says, Boliden was after a reliable industrial network architecture that can operate in its mine, could allow machinery to operate autonomously to keep workers out of dangerous areas, and could improve operational efficiencies in the mine while reducing costs.

Working with Boliden and Sandvik Mining and Rock Technology, one of Cisco’s first few Design-In Program partners, the company came up with a solution.

The network installed at the mine allows large machinery, such as Sandvik LH517s, to operate remotely and autonomously in areas that could be unsafe to send people. With the support of Sandvik’s AutoMine® for autonomous mining equipment and Sandvik’s OptiMine® software to analyse and optimise production, Boliden mining engineers can remotely (and safely) operate the machinery from a control room, it says.

This also makes it possible for Boliden mining engineers to work in a cleaner, healthier environment, according to Cisco.

Sandvik ramps up Automine truck automation efforts

Sandvik says it has released a new solution that will allow automated underground trucks to continue seamlessly through ramp portals to the surface to complete the dumping cycle.

Having offered a sneak peek of this product at the Digitalization in Mining event in Brisbane, Australia, in December, the company has now gone public with the launch.

AutoMine® for Trucks is a first for autonomous ramp haulage applications in the underground mining industry, providing autonomous truck haulage not only in underground environments but also now on the surface, according to the company. “It turns Sandvik’s intelligent mining trucks into unmanned robots; robots that keep running,” Sandvik said.

For many years, mining operations across the world have benefitted from Sandvik’s intelligent AutoMine systems for autonomous and unmanned truck haulage. “They help to reduce equipment damage, repair work and add the highest levels of efficiency and fleet utilisation, giving a lower cost per tonne,” the company says. They are scalable for different mining applications and can be supervised from remote locations.

Riku Pulli, Vice President, BU Automation, Sandvik Mining and Rock Technology, said: “Continuously setting the industry standard, we have now developed the industry-first, fully autonomous underground trucks that can operate in mining levels and mine declines including both underground and surface sections. These trucks are set to revolutionise the mining industry, bringing significant improvements in mine’s productivity and safety.”

A key requirement for an autonomous ramp haulage application is to enable the capability for trucks to operate autonomously not only underground but also on the surface. With this product release, Sandvik has unlocked this capability for its customers, it says.

The different elements of the newly added capabilities have been tested at many of mine sites with existing experience of AutoMine for Trucks, a Sandvik spokesperson confirmed.

A core innovation behind the new capability is the smart handover technology that allows trucks to switch from underground to surface navigation mode in real time. This allows trucks to continue through the ramp portal seamlessly to the surface to complete the dumping cycle.

AutoMine also connects directly to Sandvik OptiMine®, enabling production planning and automatic dispatching of tasks to AutoMine for production execution, according to Sandvik. The progress of production tasks is reported back to OptiMine giving mines real-time visibility of their automated and manual operations and enabling them to make informed decisions on their operation.

Other benefits of OptiMine include equipment and people location tracking, 3D mine visualisation and predictive analytics to transform data into actionable insights. Integration with My Sandvik Productivity allows mines to keep track of their trucks’ condition and know the real-time status of the fleet, the company says.

Sandvik slots new DU412i automated drill into ITH longhole range

Sandvik says it has launched its first automation-ready underground ITH longhole drill for production drilling, service support and mechanised slot raising.

The DU412i is a “truly versatile automated ITH longhole drill for a wide range of ITH applications”, it said.

For the first time in the global market, the DU412i introduces mechanised pipe handling in V–30 slot raising applications, according to Sandvik.

Its first fully automated ITH longhole drill, the DU412i has a drilling module for fan or parallel Ø90-216 mm longhole drilling, using 3-8 in ITH hammers. Equipped with the V-30 head, the drill provides mechanised reaming of Ø30 in slot raises, it says.

The DU412i is available with high capacity on-board boosters and hammer pressure up to 28 bar. “This ensures higher penetration rates, drilling capacity and supports hammers up to 8 in at 24 bar pressure,” it said. “The increased boom offset of parallel holes to 3,000 mm allows more holes to be drilled each set-up.”

The DU412i has automation packages for repeating drilling cycles with speed and precision, Sandvik says. Unmanned drilling through breaks and shift changes increases fleet utilisation; one operator can supervise multiple units, improving product safety and productivity.

The drill is also equipped with a new, improved user interface on the drill or in the remote-controlled location.

The standard Silver drilling automation package features single-hole automation (including uncoupling of pipes), while the optional Platinum package delivers fan automation, drill plan management and as-drilled data download.

Teleremote drilling operation on the DU412i improves productivity and product safety, according to the company. “Radio-remote tramming gives the operator excellent visibility of the work area to safely tram the unit between fans and set it up very precisely without being in the operation area.” The tramming is possible on either diesel power or using the electric power pack, it said.

The FOPS/ROPS cabin on the DU412i is the safest and the most comfortable working environment in underground drilling, Sandvik claims. It offers a more open and spacious environment for the operator with increased visibility and low sound pressure level during drilling of <75 dBA.

An adjustable drilling control panel and seat improve operating comfort during operation, while tramming teleremote cameras are available, it said.

In the V-30 slot raising configuration, the unit is delivered with blind bore feed and split centraliser, spaced out RH6250 rotation head and PC225 carousel. The storing capacity of the carousel allows up to 40 m of continuous drilling and slot raising.

The unit is fitted with KSU34 on-board booster (34 m³/min at 28 bar) and single-hole automation for Ø6.5 in pilot hole drilling, while, for reaming, the pilot to Ø10 in can be used. Pipe handling during reaming the raise to Ø30 in with the V–30 head is mechanised, meanwhile.

The layout of the carrier allows ground access to all service points, while swing-out frames offer ease of access to other components and safety in service, Sandvik concludes.

Kibali automation journey to be discussed at SME Conference

One of the most autonomous underground mines in the world, Barrick Gold’s Kibali operation in the Democratic Republic of the Congo (DRC) recently hit another annual production record.

The mine soared past its 2019 production guidance of 750,000 oz of gold, with 814,027 oz being delivered. This topped the previous 2018 record of 807,251 oz.

At this year’s SME MineXchange Annual Conference & Expo, in Phoenix, Arizona, on February 26, Ismali Traore, Kibali Technical Services Manager, is to reveal more about how the operation has continued to surpass expectations and how safety has become front and centre at the mine, owned 45% by Barrick, 45% by AngloGold Ashanti and 10% by SOKIMO.

In his conference abstract, Traore said, in recent years, the mine has made significant progress by implementing a fully automated production level and material handling system (MHS) at the underground mine.

This sees up to three LHDs operated simultaneously from ore passes to the crusher and multiple LHDs from the stope to the finger raises. The entire automation system is remotely operated from a control room located on surface.

In a recent presentation, the Kibali partners said the system was designed to have autonomous Sandvik LH621 LHDs work in combination with a Sanvdik AutoMine loading system (ALS). The ALS Mission Control System is incorporated with features such as traffic management, auto-loading and tipping with real time tonne-kilometres/h, and a real-time bucket weighing system that is within 3% accuracy level for each bucket trammed to the coarse ore bins (COB) at the operation.

The MHS, meanwhile, uses data obtained from the ALS to interface with SCADA via an OPC interface, according to the partners. COB levels from the SCADA system are then interfaced with ALS to manage the loading of the bins.

All information is interfaced to achieve the nameplate capacity of the hoisting system – which WorleyParsons provided the operating philosophy for and Winder Controls (member of the SIEMAG TECBERG Group) provided the winder design for – while taking into consideration the availability of the ALS to equate the total MHS availability, they said.

In its objective of becoming one of the most efficient Tier One mines globally where safety is a focal point of the operation, a significant amount of time was spent on the traffic management and human interaction with the autonomous mining equipment, Traore said.

This is something Barrick President and Chief Executive, Mark Bristow, picked up on last month, saying the mine is continuing its technological advance with the introduction of truck and drill training simulators and the integration of systems for personnel safety tracking and ventilation demand control.

Traore is to expand on the important safety protocols implemented to mitigate the risk of collision between this equipment and humans within the automated system during his presentation.

Steering the electric mine revolution

Sandvik Mining and Rock Technology, last year, made a clear statement to the underground mining equipment sector with the acquisition of Artisan Vehicle Systems: the future is electric.

With this acquisition having bedded in and International Mining EventsThe Electric Mine 2020 conference, in Stockholm, Sweden, just around the corner, IM caught up with Sandvik Mining and Rock Technology President, Henrik Ager, to get his views on current industry demand for electric solutions and what other elements could come into the OEM’s electrification offering in the future.

IM: In your keynote presentation title for the upcoming conference you have highlighted two benefits to electrification, namely ‘productivity’ and ‘sustainability’. Would you say these are the two most important criteria for companies adopting, or thinking about adopting, electrification solutions?

HA: Productivity, or rather mining economics, is still the primary driver for any technology change. If applying new technology allows you to lower your cost or get more tonnes out of the operation, it tends to make sense. If it doesn’t, it rarely makes sense.

For electrification, we are getting to the point where, when you compare a diesel machine with an electric machine, the economics are starting to be on a par. The electric machines tend to be more expensive from a capital expenditure (capex) point of view, but this upfront capital is coming down; we haven’t yet made that many machines but when we scale up production the price will likely fall further.

Within this, the batteries are, of course, a big capex item. To get around this, we will most likely end up selling the battery as a service to customers, so they pay per kilowatt hour as opposed to investing outright in batteries.

Some of the benefits of using electric machines include the maintenance costs being significantly lower than with diesel-powered equipment. You are also seeing you can get more productivity out of the machines – with any electric motor, you get a lot of torque. This latter point is of use in many applications. For example, when you are running an underground loader and loading your bucket, torque control is very important. Being able to precisely control this and get as much traction from the tyres as possible allows you to more accurately load the bucket. We should, therefore, see better fill factors on the bucket with these electric drivetrains; if you end up getting 10% more in your bucket every time, it makes a difference.

From an economic point of view, you also have the potential ventilation benefits of having an electric drivetrain. The electric drivetrain will put out some heat, but it is about one eighth of what a diesel drivetrain puts out. Obviously, there are no diesel particulates either, so you need to ventilate a lot less. If you start inputting that into your mine plan, then you end up saving a lot of capex on ventilation shafts. That can bring an orebody into being economically viable where it wasn’t before. While that is not the case for all mines and orebodies, it is relevant for many of them.

IM: Does that total cost of operations argument overcome upfront capex concerns in countries that are known to be more price sensitive?

HA: There are some geographies where price is more prominent and others where it is less prominent. But, to put this into perspective, we predominantly make expensive and productive machines. We don’t make low cost or low productivity machines. So, we have been fighting with this same issue for a long time. Yes, it is more difficult to overcome capex issues in some places, but there are still customers in these areas that look at the full productivity dynamic and realise the cost of the machine is only one piece of the puzzle.

In general, the more you separate operations from procurement, the more the discussion shifts to price per machine. The closer the relationship is between operations and procurement, the more chance you have of entering a full productivity discussion.

IM: How widespread would you say interest is for mine electrification? You’re currently speaking to me from Cape Town, South Africa (at Mining Indaba), would you say it is penetrating that continent, as well as North America, Australia and Europe?

HA: Yes, is the short answer. This topic has pretty much been on the agenda in every discussion we have had this week.

One important thing often left out of this conversation is that, in southern Africa, electric loaders have been operating in mines for a long time, but they are cable electric. This is the case across the globe too. We delivered our first cable-electric machine in 1981 and have put out more of these loaders than anyone else. We have delivered 600 electric machines – most of which are tethered or cable loaders.

We have now developed a battery and cable combination machine so when you are underground in the section doing repetitive work – loading and dumping the bucket – you are on a cable, but then when you need to go to the workshop or need to move the machine to another section of the mine, you can unhook and operate on battery. The machine can also carry out a few cycles on battery-only, but this might not be as productive in certain operations.

IM: Out of those three – North America (Canada, more specifically), Australia and Europe – which region would you say is leading when it comes to adopting electrification solutions in mining? What do you put this down to?

HA: It’s Canada for two reasons.

One is the data around diesel particulates is that much more advanced in Canada. There are strict regulations for how much ventilation you need in underground mines to dilute diesel particulates and exhaust gases.

The second – which is also linked to the first one – is that many mines in Canada are going deeper or further away from existing ventilation and cooling infrastructure. As well as the obvious health benefits, the cost of new ventilation shafts and refrigeration can be offset by using electric machines, since they produce zero exhaust emissions and much lower heat.

IM: In terms of your mine electrification offering, Sandvik recently completed the acquisition of battery-electric vehicle leader Artisan, adding to the company’s long history of delivering cabled machines powered by electricity. Do you currently see any other technologies on the market that you might acquire/build to further your status as a leader in mine electrification solutions?

HA: We are looking at a diesel-battery hybrid as an option. We need to, again, see that the economics stack up as these will be more expensive machines to manufacture. We need to answer the questions: Will that machine be more productive? Will it be faster up the ramp? And will it be more practical than using battery-electric only?

We need to see what the case is here and work with our customers.

A couple of the mining contractors are really pushing for the development of these machines. It’s good to work with the contractors on such projects as they are so heavily focused on economics and productivity. They may bid on, for example, developing a 2 km decline into the mine. The cheaper they can do that from a complete project cost point of view, the more competitive they will be and the more projects they will win. So, they really know their numbers and can clearly factor in new technology to these calculations.

As previously mentioned though, if the economics on that machine don’t make sense, it is hard to make things work.

IM: Do you think this speaks to the fact there will be a variety of solutions that help miners ‘go electric’ in the future?

HA: Absolutely. It is not going to be one-size fits all. Some mines are going to go with battery-electric haulage and loading, some will go for hybrid solutions, others cable and some are just going to go with the cleanest diesel machine they can find and, in turn, ventilate as that is the only thing that practically works with them.

IM: Anything else to add on this subject?

HA: For me, it is important to balance the view of how fast the pickup of this technology will be.

It will take some time like it has with every other new technology in mining – it will be different solutions in different places – but I think there is a very bright future for electrification in mining. We simply have to move in that direction.

Henrik Ager will present ‘Productivity and sustainability through electrification’ in the keynote slot at The Electric Mine 2020 conference, in Stockholm, Sweden, on March 19. His presentation will also be streamed on Sandvik Mining and Rock Technology’s LinkedIn page. For more information on the event, click here.

Barrick continues to adopt new technologies at Kibali gold mine

Barrick Gold says its 45%-owned Kibali gold mine in the Democratic Republic of the Congo is continuing its technological advances with the introduction of truck and drill training simulators and the integration of systems for personnel safety tracking and ventilation on demand.

The mine, which is owned 45% by AngloGold Ashanti and 10% by SOKIMO, surpassed its 2019 guidance of 750,000 oz in 2019, delivering 814,027 oz in another record year, Barrick said this week.

Barrick President and Chief Executive, Mark Bristow, told a media briefing that Kibali’s continuing stellar performance was a demonstration of how a modern, Tier One gold mine could be developed and operated successfully in what is one of the world’s most remote and infrastructurally under-endowed regions.

He also noted that, in line with Barrick’s policy of employing, training and advancing locals, the mine was managed by a majority Congolese team, supported by a corps of majority Congolese supervisors and personnel.

Kibali is already one of the world’s most highly automated underground gold mines, with the operation’s backbone being Sandvik’s Automine Multi Fleet system, supervised on surface by a single operator. In a world first, it allows a fleet of up to five LHDs to be operated autonomously, 750 m below the surface, within the same 6 m x 6 m production drive while using designated passing bays to maintain traffic flow, the company says. A similar system is used in the production levels to feed the ore passes, according to Barrick.

The company said it had now introduced truck and drill training simulators and integrated systems for personnel safety tracking and ventilation demand control, adding that the simulators will also be used to train operators from Barrick’s Tanzanian mines.

Bristow also said that the company was maintaining a strong focus on energy efficiency at the mine through the development of its grid stabiliser project, scheduled for commissioning in the June quarter of 2020.

He said: “This uses new battery technology to offset the need for running diesel generators as a spinning reserve and ensures we maximise the use of renewable hydro power. The installation of three new elution diesel heaters will also help improve efficiencies and control power costs. It’s worth noting that our clean energy strategy not only achieves cost and efficiency benefits but also once again reduces Kibali’s environmental footprint.”

Bristow said despite the pace of production and the size and complexity of the mine, Kibali was maintaining its solid safety and environmental records, certified by ISO 45001 and ISO 14001 accreditations.

Artisan releases largest battery-powered underground truck

Sandvik-owned Artisan Vehicle Systems has upped the stakes in the battery-electric underground haulage game by introducing a new 50 t haul truck.

The company made the announcement at the Digitalization in Mining event, in Australia, held by Sandvik on December 3-4, 2019.

The Z50 is based off the existing design for the Z40 truck, which Artisan released back in 2018, but features a stretched rear frame (close to 19 in) to allow for the 50 t box, an Artisan spokesman confirmed.

It has become the largest battery-powered underground truck on the market, topping the Epiroc-produced MT42 battery-powered vehicle, which has a 42 t capacity. Despite the payload increase, Artisan says the technology and design makes it the “smallest 50 t truck on the market”, generating twice the peak horsepower and one eighth the heat of its diesel equivalent.

Artisan, which was acquired by Sandvik Mining and Rock Technology last year and is now part of its Load and Haul division, also worked in some notable upgrades to the Z50 such as the solid-state electronics, the spokesman added.

It is powered by four electric motors generating 560 kW and 8,200 Nm of torque and, like the other Artisan battery-powered vehicles on the market (the A4 and A10 LHDs), uses lithium-iron-phosphate chemistry for the patented battery system.

ICMM looks to align mining industry on cleaner, safer vehicles

When the International Council on Mining and Metals (ICMM) launched its Innovation for Cleaner, Safer Vehicles (ICSV) program just over a year ago, some industry participants may not have realised how much progress could be made so quickly by taking a collaborative approach.

The ICMM has proven influential across the mining industry since its foundation in 2002 in areas such as corporate and social governance, environmental responsibility, and stakeholder relations, yet it has rarely, until this point, engaged directly as an industry group with original equipment manufacturers (OEMs) and service providers.

Close to 12 months after being established, it’s clear to see the program and the council itself has been successful in bridging a divide.

It has been able to corral a significant portion of the mining and mining OEM market players into a major industry discussion on core focus areas set to dominate the sector for the next two decades.

Now 27 of the world’s leading mining companies and 16 of the best-known truck and mining equipment suppliers are collaborating in a non-competitive space “to accelerate the development of a new generation of mining vehicles that will make vehicles cleaner and safer,” the ICMM says.

The ICSV program was created to address three of the most critical safety, health and environment performance issues in the ICMM’s mission towards zero harm and decarbonisation. Achieving this goal would involve the industry introducing and adopting the next generation of equipment to respond to the challenges.

More specifically, the program aims to:

  • Introduce greenhouse gas emission-free surface mining vehicles by 2040;
  • Minimise the operational impact of diesel exhaust by 2025; and
  • Make collision avoidance technology (capable of eliminating vehicle related collisions) available to mining companies by 2025.

In all three, it seeks to address the industry’s innovation challenge of ‘who motivates who’ or the chicken and egg analogy, according to Sarah Bell, Director, Health, Safety and Product Stewardship for the ICMM.

“You can imagine a mining company saying, ‘we can’t adopt technology that doesn’t yet exist’ or an OEM saying, ‘we can’t invest in development because we’re getting mixed market signals’. This is, of course, why this program has been set up in the way it has,” she told IM. “Bringing both the mining company and OEMs together, they have been able to work through these normal innovation challenges and align on defining the direction of travel and critical complexity to be solved for each of the ambitions set.”

High-level participation

The list of companies the ICMM has been able to involve in this program is impressive.

It is being guided by a CEO advisory group of six; three from the mining community – Andrew Mackenzie (CEO, BHP), Mark Cutifani (CEO, Anglo American) and Nick Holland (CEO, Gold Fields) – and three from the mining equipment supply side – Denise Johnson (Group President of Resource Industries at Caterpillar), Max Moriyama (President of the Mining Business Division at Komatsu) and Henrik Ager (President of Sandvik Mining and Rock Technology).

On the mining company front, ICMM membership makes up around 30% of the total metal market share, with some 46% in copper, 27% in gold and 42% in iron ore. Participating OEMs and third-party technology providers, meanwhile, include the three majors above, plus Cummins, Epiroc, Wabtec Corporation (formerly GE), Hexagon Mining, Hitachi Construction Machinery, Liebherr, MacLean Engineering, MTU, Modular Mining Systems, PBE Group, Nerospec, Future Digital Communication and Miller Technology.

Bell says the high-level participation builds the “widespread confidence” needed to accelerate investment in these three key areas”, while the ICMM’s focus on the leadership side of the technology integration equation and change management has proven “absolutely key”.

She clarified: “This collaboration operates under anti-competition and anti-trust rules. Our role is to convene the parties, motivate action and promote solutions.”

The program offers a “safe space for the OEMs and members to work openly in a non-competitive environment”, she added, explaining that the aim is not to come up with “preferred technologies”, but define the “functional and operational pathways required to meet the ambitions set”.

Vehicle interaction (VI)

Some of the ambitions look easier to achieve than others.

For instance, collision avoidance and proximity detection technology has made huge strides in the last decade, with the ICMM arguing its 2025 target is like a “sprint”, compared with the “10,000 m race” that is minimising DPM underground by 2025 and the longer-term aim to introduce GHG-free surface mining vehicles by 2040.

“There are regulations that require implementation of collision avoidance and proximity detection technology by the end of 2020 in South Africa,” Bell said. This will undoubtedly provide a catalyst for further developments to speed up.

The ICSV program is also leveraging the work of the Earth Moving Equipment Safety Round Table (EMESRT) in its development of fundamental functional/performance requirements for operators and technology providers.

These requirements were updated and released by EMESRT in September and are known as ‘PR5A’.

Credit: Hexagon Mining

Bell delved into some detail about these requirements:

“The EMERST requirements are designed around a nine-level system that seeks to eliminate material unwanted scenarios such as – equipment to person, equipment to equipment, equipment to environment and loss of control,” she said.

“The fundamental change with this newly released set of functional requirements by EMESRT is that the mining industry users have defined the functional needs for levels 7-9 (operator awareness, advisory controls, and intervention controls). That stronger level of collaboration hasn’t necessarily been there.”

EMESRT and its guidelines have been given an expanded global platform through the ICMM’s ICSV, with the program, this year, providing the convening environment for users and technology providers to help finalise these updated requirements, according to Bell.

With all of this already in place, one could be forgiven for thinking the majority of the hard work involved with achieving the 2025 goal is done, but the working group focused on VI knows that while OEMs continue to retrofit third-party vehicle collision and avoidance systems to their machines the job is not complete.

“Let’s think about the seatbelt analogy: you don’t give buyers of vehicles a choice as to whether they want a seatbelt in their car; it just comes with the car,” Bell said.

“At the moment, by design, vehicles don’t always have this collision and avoidance systems built in, therefore there is a big opportunity for collaboration between OEMs and third-party technology providers.”

Underground DPM goals

“The DPM working group have recognised that, in the case of the DPM ambition, ‘the future is already here, it’s just unevenly distributed’,” Bell said.

“Bringing together the OEMs and the mining companies this year through the ICSV program has enabled the group to explore the variety of existing solutions out there today,” she added.

These existing solutions include higher-tier engines, battery-electric equipment, tethered electric machinery, fuel cell-equipped machines for narrow vein mining and solutions to remove DPMs and other emissions from the environment like Johnson Matthey’s CRT system.

And, there are numerous examples from North America – Newmont Goldcorp at Borden, and Glencore and Vale in Sudbury – South America – Codelco at El Teniente Underground – and Europe – Agnico Eagle Mines at Kittilä (Finland, pictured) – to draw from.

Bell also mentioned some examples from Australia where regulatory changes have seen miners apply existing technology and carry out changes in their work plans and maintenance practices to minimise DPM emissions.

Haulage and loading flexibility, battery charging and mine design have all come under the spotlight since these new generation of ‘green’ machines have emerged, so achieving the 2025 goal the ICSV stated is by no means a foregone conclusion.

“There remains more work to do in achieving diesel-free vehicles underground,” Bell said.

The interested parties are aware of this and the program’s DPM maturity framework is helping miners and OEMs plot a course to reaching the target, she explained.

“The DPM maturity framework promotes existing solutions available today that would enable a mining operation to reduce their DPM emissions to a level that would meet the ambition level (shown as Level 4 – transition to zero),” she said.

These frameworks are useful for starting a “change conversation”, Bell said, explaining that mining companies can assess within their organisations where they currently sit on the five-level chart and discuss internally how to move up the levels to meet their goals.

These same frameworks look beyond minimising “the operational impact” of DPM emissions underground, with Bell explaining that Level 5 of the maturity framework involves “non-DPM emitting vehicles”.

GHG-free surface mining vehicles

Even further in the distance is the longer-term target of introducing greenhouse gas emission-free surface mining vehicles by 2040.

This ambition, more than any other, is less clearly defined in terms of technological solutions across the industry.

While battery-electric solutions look like having the goods to reach DPM-free status underground with expected developments in battery technology and charging, the jury is still out on if they can create a GHG-free large-scale open-pit mining environment.

The world’s largest battery-electric haul truck – eMining’s 63-t payload eDumper (pictured) – may have proven its worth at a Ciments Vigier-owned quarry in Switzerland, but the world’s largest open-pit mines require a solution on another scale altogether.

As Bell said: “There is a lot of work to do to develop batteries at scale for surface fleet that suit the different operating conditions.

“That’s a key point because that lends itself to the fact that we don’t want one solution; we will need multiple solutions. We don’t want to stifle innovation; we want to encourage it.”

ICMM member Anglo American has hinted that hydrogen power could be one solution, and the miner is looking to show this next year with the development of its hydrogen-powered 300-t payload haul truck.

There has also been in the last 18-24 months a mini renaissance of trolley assist projects that, ABB’s Gunnar Hammarström told IM recently, could, in the future, work in tandem with battery-powered solutions to provide a GHG-free solution.

The ability for industry to pilot and validate technology options like this “within the boundaries of anti-competition” is crucial for its later adoption in the industry, Bell said.

She said a key enabler of industry decarbonisation is access to cost competitive clean electricity, which would indicate that regions like South America and the Nordic countries could be of interest in the short and medium term for deploying pilot projects.

It is this goal where the industry R&D spend could potentially ramp up; something the ICMM and the ICSV is aware of.

“For the OEMs and mining companies to effectively minimise capital expenditure, optimise R&D expenditure and reduce the change management required by the industry, there needs to be a careful balance of encouraging innovation of solutions, whilst managing the number of plausible outcomes,” Bell said.

In terms of encouraging the development of these outcomes, carbon pricing mechanisms could provide some positive industry momentum. Vale recently acknowledged that it would apply an internal carbon tax/price of $50/t when analysing its future projects, so one would expect other companies to be factoring in such charges to their future mine developments.

Industry-wide GHG emission caps could also provide a catalyst. In countries such as Chile – where up to 80% of emissions can come from haul trucks, according to ICMM Senior Programme Officer, Verónica Martinez – carbon emission reduction legislation could really have an impact on technology developments.

Forward motion

While 2019 was a year when the three working groups – made up of close to 50 representatives in each work stream – outlined known barriers or opportunities that might either slow down or accelerate technology developments, 2020 will be the year that regional workshops convened to “encourage first adopters and fast followers” to move these three ambitions forward take place, Bell said.

A knowledge hub containing the previously spoken of maturity frameworks (delivered for all three groups) will allow the wider industry outside of the ICMM membership to gain a better understanding of how the miner-OEM-service provider collaboration is working.

Bell said the ICMM already has a number of members testing these group frameworks on an informal self-assessment basis to understand “how they are being received at an asset level and feedback insights to the group in an effort to understand how we may portray an industry representative picture of where we are today”.

Such strategies bode well for achieving these goals into the future and, potentially, changing the dynamic that has existed between end users and suppliers in the mining sector for decades.

Bell said: “The feedback that we got from OEMs is that mining companies had completely different objectives, but they have now greater confidence that we are aligned on the direction of travel towards the ambitions set.”

Sandvik’s largest electric LHD receives an upgrade as it heads to Kiruna

Sandvik says it is preparing to deliver its renewed Sandvik LH625iE electric loader for field testing at the LKAB-owned Kiruna mine, in northern Sweden.

The unit to be tested is the 600th electric loader from Sandvik, and is custom-designed to meet the needs of the underground iron ore mine, it said.

The underground loader, which features a 9.5 m³ bucket and 25,000 kg payload capacity, is designed to operate in the world’s largest underground iron ore mine.

The basic LH625iE design is well-proven (and based on the LH625E, pictured), according to Sandvik, with the equipment manufacturer delivering electric loaders powered by a trailing cable for more than 35 years.

In addition to using the proven design and robust structures, today’s Sandvik LH625iE belongs to its i-series, featuring advanced technology, latest digital solutions and smart connectivity. This sees the new Sandvik LH625iE equipped with Sandvik Intelligent Control System and My Sandvik Digital Services Knowledge Box™ as standard. To utilise the payload capacity it offers, the loader can also be fitted with Sandvik’s Integrated Weighing System, as well as AutoMine® and OptiMine® solutions, Sandvik said.

With a total length of 14 m, bucket width of 4 m and cabin height of 3 m, the LH625iE is able to offer a roomy, ergonomically designed operator’s compartment, Sandvik said. “For example, the spacious cabin is equipped with a unique 180° turning seat which significantly improves operator ergonomics because it can be turned to face in the direction of travel rather than requiring over-the-shoulder visibility. The upgraded Sandvik LH625iE has an IE4 classified energy-efficient electric motor, with a further significant improvement being the totally new, low-tension reeling system to increase the trailing cable’s lifetime. “

The collaboration between Sandvik and LKAB’s mine in Kiruna dates back 20 years, during which time Sandvik has delivered a total of 28 loaders.

Michael Palo, Senior Vice President, Northern Division at LKAB, said: “We are satisfied with the loaders delivered from Sandvik, with 14 still in production today. We have had a long and good collaboration and look forward to a good continuation.”

Sandvik concluded: “The Sandvik LH625iE is living proof that it is possible to achieve enormous carrying capacity and productivity without the use of traditional diesel engines and fossil fuel.”

Battery-electric loaders are also providing evidence of this, with Sandvik saying it had received positive results from its testing of Artisan A10 battery-electric loaders in Canada.

Sandvik showcases digital mining developments in Brisbane

Last week, close to 300 leaders from the mining, construction and quarrying industries from Australia, Japan and Indonesia met in Brisbane, Australia, for a two-day summit, hosted by Sandvik, to showcase best practice examples of digitalisation.

The Digitalization in Mining event, on December 3-4, allowed Sandvik to demonstrate its latest digital offering and introduce participants to the latest innovations across its product portfolio, including process optimisation with OptiMine®, information management through My Sandvik digital services and autonomous operation with AutoMine ̶ together with the latest equipment in underground and surface drilling, loading and hauling, crushing and screening and the rock tools management system.

During the event Sandvik also announced two product launches: AutoMine Access API, which gives mines the power to connect non-Sandvik equipment to AutoMine, and its first Stage V compliant underground loaders for hard-rock mining applications.

Jim Tolley, Vice President, Sales Area Australia Pacific, Sandvik Mining and Rock Technology, said digitalisation is helping companies to grow and optimise their operations. “Our partners were keen to join us at this event because they know that digitalisation has a critical part to play in making their mines sustainable for the future.”

Day one of the event featured speakers from mining companies across Australia, as well as leaders in mining technology, process optimisation and automation. They explained the benefits their organisations have gained by implementing automation and process optimisation solutions, as well as the accompanying change in mindset, according to Sandvik.

The following presentations set the program for the day, followed by a panel discussion:

  • Shaping the Industry Digital Ecosystem (Sandvik);
  • Holistic Perspective, Focusing on Productivity, Safety and Optimised Machine Performance (Byrnecut);
  • Developing the Mine of Tomorrow (Barminco Ltd);
  • Machine Learning  ̶  Keeping it Real with Case Studies from across the Mine Value Chain (PETRA Data Science);
  • Capturing Opportunities for Digital and other Product Technology Solutions (Rio Tinto);
  • Automation Technology to Improve Efficiency and Consistency in Longwall Development Operations (Glencore);
  • Direction of Technology and Automation (Newcrest); and
  • Data Privacy, Rights and Control (Sandvik).

Pat Boniwell, Managing Director, Byrnecut Australia, said the industry will improve productivity, safety and optimise machine performance through a more “fundamental understanding” of the individual processes that make up our operations.

“New technology, automation, data transfer and analysis will all assist us in increasing the utilisation of our resources,” he said. “Data is essential, but if it is not being looked at then we are just gathering data for the sake of it. We need to continue to increase the levels of engagement between all stakeholders.”

He concluded: “We are doomed to failure unless we take our people with us and are prepared to question and be challenged.”

PETRA CEO, Penny Stewart, meanwhile, homed in on machine learning, which, she said, powers “digital twin prediction, simulation and optimisation to increase mine productivity, efficiency and yield, by showing engineers and supervisors how to reproduce their ‘best performance’ 24 hours a day, seven days a week”.

She added: “PETRA’s MAXTA™ Suite digital twin applications provide platform agnostic software-as-service operational decision support across the mine value chain ̶ from resource engineering through to processing plant set point optimisation.”

Day two of the event began with a presentation on sustainability by Henrik Ager (pictured), President, Sandvik Mining and Rock Technology, explaining how critical it is for long-term performance.

“Driving productivity and greenhouse gas efficiency together is going to be key for us at Sandvik, improving productivity and greenhouse gas efficiency will be the best way for us to add value for our customers,” he said. “My view is that the more we link our sustainability targets to normal business targets and find ways to combine them to achieve a common good, the better chance we have to deliver on them.”

Also, during the second day, delegates had the opportunity of a virtual visit to several Sandvik customers, including: Northparkes Mine (Australia), Resolute Mining Syama mine (West Africa), RedBull Powder Company (New Zealand) and Aeris Resources Tritton mine (Australia).

Harry Hardy, General Manager Customer Accounts, Applications Engineering and Marketing, Sandvik Mining and Rock Technology, Sales Area APAC, said the company often gets asked for reference cases and data to illustrate the value and payback of digital solutions. “Over the two days of the conference, our customers were able to share their own experiences and quantitatively demonstrate how our solutions have helped increase their productivity, reduce their production costs and increase their safety.”
