A MacLean EV Series™ carrier fitted with a third-party emulsion charging plant is part of the company’s expanded presence at this year’s edition of the Mining Indaba in Cape Town, South Africa.

MacLean Africa will be showcasing this latest battery-electric mining vehicle (BEV) offering outside the CTICC in front of the Cullinan Hotel during the event, which runs from February 7-10.

The Sudbury-based company has had an established, in-country presence in South Africa since 2001. This was the company’s first ever international branch and, since that time, the local sales and support team has grown in line with the expansion of the MacLean fleet deployment across the continent. The company now supports MacLean mining vehicles at customer operations across South Africa, as well as in Namibia, Tanzania, the Democratic Republic of the Congo and Mali.

MacLean Africa General Manager, John-Paul Theunissen, said: “Our message to the African mining community at Indaba is simple and I hope, resonant – MacLean is manufacturing and supporting mining equipment that is custom designed for underground mining on this continent, supported by an in-country team of skilled engineers, product managers, field service technicians, and repair and rebuild mechanics. We are here for the long haul; we have the critical mass of talent and parts and manufacturing capacity and we have your full fleet of production support mining vehicles, ready to get to work.”

MacLean President, Kevin MacLean, added: “I’m excited by what MacLean Africa has already done in terms of building out the MacLean fleet footprint across Africa and I’m even more excited by what the future holds for us in this crucial mining region. We can walk with customers as they explore options for the rollout of a battery-electric, automated, and data-rich mobile fleet that will drive the ‘no boots on the ground’ mining of the 21st century. We have it all – the present and the future of underground mining mobile equipment, technology, and services. We are above ground where your fleet is underground in Africa.”

This year is an important one for MacLean as it marks the company’s 50th year of operations. What started out as a niche, custom equipment solutions provider for the Canadian industry in the 1970s has evolved to what it now claims is now the world’s largest Canada-based manufacturer of underground mining vehicles, with a worldwide staffing contingent that surpasses 1,000 employees across four continents.

Volvo CE makes electric wheel loader investment in Arvika plant

As part of its ambition towards industry transformation through sustainable solutions, Volvo Construction Equipment (Volvo CE) has announced an investment into the production of electric wheel loaders from its plant in Arvika, Sweden.

The SEK65 million (circa-$6.3 million) investment from Volvo Group will allow the Arvika factory in Sweden – which specialises in the production of medium and large wheel loaders – to expand its facilities with a new building and allow for the phased introduction of new electric wheel loaders.

It is not only a milestone in the plant’s almost 140-year history, but a significant moment for Volvo CE and its determination to be completely fossil free by 2040, the company said. This is in line with the aims of the Paris Agreement and as laid out in the manufacturer’s industry leading Science-Based Target goals. It is also a step forward in its ambition for 35% of its machines sold to be electric by 2030.

Coming soon after an announcement to invest in electric haulers from the company’s production facility in Braås, Sweden, the announcement shows Volvo CE is committed to achieving more sustainable solutions for customers across all its product lines. These announcements are part of an investment strategy that allows Volvo CE to advance electric solutions across its production facilities, including also the Konz facility in Germany, Belley in France and Changwon in South Korea, where other electric machines are made.

Site Manager, Mikael Liljestrand, says: “This is a clear signal of our commitment to building the world we want to live in. It is more than 40 years since we last invested in a new building and what better reason now than to invest in our future, our planet and the next generation. We know that this is not only important to our customers and stakeholders, who rightly have high expectations on us, but it is also close to our hearts to be part of something bigger in building our future.”

Volvo CE has already introduced compact electric wheel loaders to the global market with the L20 Electric and L25 Electric wheel loaders proving to be efficient, zero-exhaust emission solutions capable of driving down carbon emissions while maintaining high productivity across a variety of customer applications. Together with the ECR25 Electric, ECR18 Electric and EC18 Electric compact excavators and the mid-size EC230 Electric excavator, Volvo CE has one of the largest electric ranges on the market.

Thanks to the investment, Arvika will erect a new building, approximately 1,500 sq m, which will allow the facility to free up areas inside its assembly factory to be able to build electric wheel loaders. While it has not yet been announced which models will begin their electric transformation and exactly when, production of both electric wheel loaders and more traditional wheel loaders fitted with combustion engines will continue for now on the same production line.

Volvo CE will ensure a phased introduction model by model, taking into account all aspects of the electric ecosystem as it does so, including infrastructure requirements, charging solutions, battery handling and business models. The result will be reliable mid-size and larger electric wheel loaders that can easily be integrated into customers’ business, it said.

It is not the first sustainability initiative from the Arvika facility. Despite increasing production last year, the factory managed to reduce its internal climate footprint by 350 t of CO2 thanks to a variety of emission reduction efforts.

“Our goal at the factory in Arvika, as well as Volvo CE and the entire Volvo Group is to be climate-smart and to produce fossil-free machines,” Liljestrand said. “Together, we are quite clear that we want to lead this transformation and be the driving force of more sustainable ways of working for the benefit of our planet. This investment is Arvika’s exciting first step towards electrification.”

Building work is set to begin later this year, with further announcements on when production will begin to come.

The Komatsu AZPG: bringing unique mining concepts to life

Automation, Environmental, Equipment maintenance, IoT, Mining equipment, Mining services, Mining software, Power supply for mines, Sustainable mining, , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

Seeing Komatsu’s Arizona Proving Grounds (AZPG) in person, it is easy to understand why the OEM is in a leading position when it comes to both surface mining automation and electrification.

The 660-acre (270-ha) facility is a living and breathing example of mining’s past, present and future; touring round, one can see 20-plus-year-old machines, the latest -5 ultra-class haul trucks and concept vehicles that will form the basis for future commercial autonomous and/or electric solutions.

These concept vehicles – at least when IM visited in November – included the company’s EVX battery proof of concept vehicle and the cabless IAHV autonomous mining truck concept.

The EVX is based off the basic 860E platform (a 254-t payload machine) and was shown off at MINExpo 2021. Prior to that, it had been testing out its all-battery power functionality at AZPG.

The IAHV, which debuted at MINExpo 2016, was developed by Komatsu as an unstaffed vehicle designed to maximise the advantages of such operation. It remains on show, with the company incorporating several learnings from this vehicle into its standard Electric Drive Trucks (EDT) and autonomous products.

Pat Singleton, Product Director, EDT, refers to AZPG as the “ultimate laboratory to be able to bring unique mining concepts to life”.

He added: “The testing we do at AZPG gives us the opportunity to reduce product development risk and take the validation process one step further before the products make it to the mine.”

The original focus at AZPG was the EDT product line, yet, as Komatsu has expanded its product offerings, more solutions continue to be tested or validated at the facility each year.

This testing is extensive, as was made obvious to IM while navigating an autonomous vehicle ‘assault course’ and hearing about new wet- and dry-disc brake trial combinations, higher speed tramming on autonomous haul trucks and more.

It is not just trucks subject to these try outs either, with hydraulic shovels, surface drill rigs, water trucks, dozers and other vehicles having a presence on site.

“If anything, the importance of AZPG has increased as technology has continued to evolve,” Singleton said. “AZPG allows for a single location to harmonise development efforts of all the Komatsu entities, providing research and development into our products.”

What’s more, the facility is located in Arizona’s renowned copper heartland.

This has been very useful for Komatsu, with Asarco’s Mission mine next door to the facility representing a real life mine site testing opportunity for solutions that have graduated from AZPG.

AZPG has 23 full-time staff, but its desk count is much higher, indicating the number of visitors and partners AZPG welcomes on a weekly basis from across the globe.

Some of these visitors include FrontRunner® autonomous haulage system (AHS) customers, who have, more recently, been invited to send operators to the facility for invaluable training ahead of planned autonomous deployments.

Anthony Cook, Vice President, Autonomous Systems, Mining Technology Solutions, told IM that this approach is enabling mining operations to leverage more of the benefits of AHS from day one of deployment, reducing the need to conduct a ‘soft start’ with the technology as operators come to terms with the transition from staffed to autonomous operations.

A representative from Komatsu’s dealer network was receiving training on the AHS system during IM’s visit, with Cook confirming another major mining customer and Komatsu distributors had sent operators to Arizona earlier in 2022 ahead of a planned deployment in 2023.

AHS developments are a key focus area for AZPG, with the on-site trucks testing out many different scenarios that customers could experience at their operations.

Software updates make up many of the ongoing FrontRunner AHS developments, but the company also continues to explore the use of more sensors and cameras on board its vehicles for obstacle detection and positioning. This is all geared towards improving visualisation, communication and safety, reducing potential false positives during operation and ultimately helping to improve productivity.

As for software upgrades to FrontRunner AHS, all developments are initially tested in a bench environment where the company can simulate the system. This may be within the former Modular Mining facility, also in Tucson, or at another one of Komatsu’s many testing hubs.

“Once it has passed virtual testing then final functional and stability testing is validated at AZPG before release to the customer,” Singleton said.

Some recent testing related to mixed fleet operations of staffed and autonomous trucks that originated in the lab to later emerge at AZPG has since led to a FrontRunner first at Anglo American’s Los Bronces mine in Chile.

The mining company only recently started its AHS deployment at the copper mine, initially going live with ten 930E-5 trucks, but Cook confirmed to IM that these vehicles are now interacting with staffed trucks in the mining environment.

“We’ve got off to a very strong start at Los Bronces, with Anglo American really embracing the technology and pushing it to its limits,” he said.

The full Los Bronces deployment could see 62 electric drive Komatsu 930E trucks running by 2024.

Those who visited MINExpo 2021 in Las Vegas will also remember the PC7000-11 shovel that was being teleremote operated live from the show, while the unit was over 600 km away at AZPG. This unit (above) is still positioned on site and the teleremote operation is continuing to be refined from inside the facility, with AutoSwing and AutoDump functions a few recent notable additions for improved operability.

Komatsu expects to replace this shovel with a backhoe version later this year, to also be teleremotely operated.

Trolley transformation

The first vehicle IM saw when driving up to AZPG was the EVX; its shiny yellow exterior providing the perfect contrast to the rich blue backdrop of the Tucson sky.

Since leaving Las Vegas in September 2021 and heading for Tucson, the company has made preparations to remove the small on-board battery which was displayed on the Komatsu stand and begin replacing it with a larger one from one of its integration partners.

The connectors for trolley were still on board and the team was awaiting final commissioning of the on-site trolley line ahead of further testing.

Singleton explained: “The EVX was a proof of concept to demonstrate that a large electric drive haul truck could be powered by a battery. Now that we better understand the ability of this technology to work in our EDT products, we must continue to advance the technology to drive increased performance and reduced operating costs.”

To date, Komatsu has continued with truck testing to learn how the various subsystems work with batteries while finalising its battery chemistry.

“We’ve also installed trolley infrastructure, which will allow us to conduct further testing on batteries and other alternative power sources,” Singleton said.

This infrastructure – made up of 39 poles that are ‘movable’ and ‘self-supporting’ – could support two 980E-5s running on the line at the same time.

Initially, it will support both the EVX and one 930E running in tandem.

The line itself is powered by a 9 MW substation, which Siemens and a local electrical and engineering company established.

The trolley course has been designed with a 60° corner to demonstrate to operators that this technology is for more than just straight hauls.

“This highlights the flexibility of the system and shows mining operators where the technology can already go today,” Cook said. “The concrete pillars, which can be moved with wheel loaders and other support equipment, are an indication that the trolley can ‘move with the mining’, too.”

Singleton said the next development for the EVX will focus on an increase in the battery capability and the investigation of proof of concept on a variety of static and dynamic charging options.

The trolley line will, no doubt, play a role in this testing, although it is not yet known if a single or hybrid power setup will be selected initially.

What is more certain, however, is the status of fuel cell electric vehicle (FCEV) testing on the EVX. Singleton said research into this area continues, yet a practical test where fuel cells and a battery were mounted on the chassis was some way off.

At this early stage, Singleton says the first commercial power-agnostic offering the company establishes will likely be diesel and/or diesel trolley.

He explained: “This approach delivers reduced risk to the overall portfolio by blending the power-agnostic chassis with a refined version of an existing technology (diesel engine + overhead dynamic trolley).”

“It also serves the secondary purpose of allowing battery technology the opportunity to mature from a performance perspective as we work to define overall truck fleet performance. Additionally, static and dynamic charging options (including development of an industry-standard connector) are within the scope of this product.”

And the first commercial power-agnostic truck will be in the 291 t (320 ton) class – the same size as a 930E – Singleton confirmed, adding that scalability was something being considered at every stage of the truck’s development.

“Scalability is the overall goal and is in alignment with the general power-agnostic approach to our design,” he said. “The major challenge will be the scalability of the energy storage componentry from a cost and performance standpoint. This is the primary driver behind the continued deliberate development cadence designed to give the battery technology time to mature over the intervening period before the design is finalised.”

When asked about fixed fast charging – a concept that has risen up the mine truck charging rankings of late with Charge On Innovation Challenge work from Hitachi Energy and a consortium led by Shell, respectively – Singleton referred to developments as a “two-way street” and a “work in progress”.

“Essentially those solutions need better definition and ‘mining proofing’ before we introduce them into AZPG,” he said. “Perhaps an opportunity exists to co-develop these technologies and improve speed to market but, again, this is still being defined.”

The trolley infrastructure at AZPG – made up of 39 poles that are ‘movable’ and ‘self-supporting’ – could support two 980E-5s running on the line at the same time, according to Komatsu

All this work sounds encouraging for those companies interested in adding to their ultra-size class truck fleets in the 2030s in line with industry-wide decarbonisation plans, but Komatsu customers looking to buy trucks today will be after future-proofed solutions.

Komatsu is all too aware of this and planning to provide a battery retrofit solution for its current -5 products, Singleton said.

GHG Alliance and beyond

As has been well documented, Komatsu has aligned with a core group of customers under its GHG Alliance to accelerate developments on the electric haulage front.

Rio Tinto, BHP, Codelco, Boliden, Teck, Antofagasta Minerals SA and Freeport-McMoRan are key stakeholders within the alliance and will be keen to see what testing emerges on that trolley line into 2023.

While Singleton said the communication process with these customers was still being refined, he acknowledged AZPG’s role in future developments.

“There is no question AZPG will provide a critical backdrop to accelerating our efforts and streamlining our ability to communicate and advance the development progress with our customers,” he said.

Whether the company chooses to initiate an early-learner program like the other big yellow equipment maker it competes with is yet to be seen, with Singleton saying its plans will leverage the “Komatsu approach” regardless of what the competition is doing.

What is clear is that AZPG will continue to keep Komatsu on the leading edge of mobile mining equipment technology developments.

As evidence, Cook reeled off several ongoing projects the company was engaged in, including an autonomous water truck in Australia, automated dozers in Brazil and plans to semi-automate electric blasthole drills.

Going forward, another consideration will be the ability to integrate AHS with trolley operations.

“Komatsu, as an organisation, is committed to solving our customer’s and the industry’s challenges, and we will continue to leverage AZPG and the wider Komatsu network to do this,” Cook said.

Antofagasta’s automation and electrification journey bearing fruit

Automation, Base metals, Environmental, Mining equipment, Mining safety, Mining services, Mining software, Power supply for mines, Sustainable mining, , , , , , , , , , , , , , , , , , , , , ,

Antofagasta’s purpose of ‘Developing Mining for a Better Future’ has seen the Chile-based copper producer lead from the front in terms of the adoption of both automation and electrification.

The company launched a digital roadmap all the way back in 2017, which, over the following years, has seen it advance projects to automate blasthole drills and haulage trucks, leverage remote operation centres and integrate advanced data analytics into its decision-making process.

Backed by a digitally-literate talent pool and underwritten by a series of roadmap and plans, Antofagasta is setting itself up for the long term.

When it comes to electrification, the company has played a key role in furthering research on the use of hydrogen fuel cells in haulage applications on mine site conditions. It has also signed up as a patron in the Charge On Innovation Challenge, being one of 19 companies looking to accelerate commercialisation of interoperable solutions that can safely deliver electricity to large battery-electric off-road haul trucks.

Outside of consortium projects, it has announced plans to also study and test the development of battery-powered trucks at its Antucoya operation and has outlined plans for a trolley assist pilot project at the Los Pelambres copper mine in Chile.

And, in April 2022, the company reached the goal of all its mines operating on fully renewable power.

Alan Muchnik, VP Strategy & Innovation for Antofagasta, says all of these developments epitomise the company’s overarching aims.

“The objective we have is to develop the next generation of mining practices to enable growth and reduce our company’s environmental footprint,” he told IM.

In addition to the digital roadmap the company outlined five years ago, Antofagasta has been carrying out all its electrification projects under the guise of an Electromobility Plan – part of its wider climate change strategy.

Following the achievement of its previous emissions reduction target of cutting both its Scope 1 and Scope 2 carbon dioxide emissions by 300,000 tonnes of CO2e between 2018 and 2022 – a goal it achieved two years early – the company set a more ambitious target in 2021. This is looking to achieve carbon neutrality by 2050 – in line with Chile’s national commitment – and reduce emissions by 30% by 2025, relative to 2020 performance. One element of the company’s efforts to reduce emissions has, as mentioned, seen its operations run solely from renewable energy as of April this year.

According to Antofagasta’s own calculations, in 2020, two-thirds of its greenhouse gas emissions from diesel combustion were attributable to its mine haulage trucks.

Komatsu 980E-5 trucks at Esperanza Sur (part of Centinela)

“In this respect, Antofagasta is actively participating in initiatives that seek to replace the diesel used by mining haulage trucks,” Muchnik said.

“As part of that electromobility roadmap, we have considered our participation in early-adoption projects with a view to pilot and scale promising technologies.”

With the HYDRA Consortium – which includes Antofagasta, ENGIE, Mining3, CSIRO Chile, Liebherr and Mitsui & Co – specifically, the company has been one of the driving forces of hydrogen haulage adoption on mine site conditions.

It has confirmed that it will test a fuel cell and battery powertrain propulsion system at its Centinela mine, with the first HYDRA prototype expected to start functional testing shortly. This will allow Antofagasta to assess the powertrain’s behaviour and performance under real mine conditions, including at high altitude with suspended dust. It will also help establish technical and safety protocols for hydrogen use at scale in mining, which will be vital for the fuel’s successful deployment across the industry.

The trolley assist project at Los Pelambres under study, meanwhile, consists of implementing a trolley system on, first, uphill ramps. This will consist of one lane of a two-lane ramp, which will allow for trucks coming behind to leave the trolley and overtake a stopped truck still on the line.

“Some of these projects may bring an early opportunity to transform specific sites as we transition towards the longer-term prevailing solution to implement at our sites and help reduce our Scope 1 footprint,” Muchnik said.

“Each mine has their unique characteristics and different technologies may become more attractive depending on those characteristics or may become complementary in enabling that diesel replacement.”

Of course, automating the haulage and blasthole drilling processes will help the company reduce its Scope 1 emissions through more efficient operations. It will also help offset some of the higher costs of inputs and inflation that come with operating in Chile.

Similarly, all of Antofagasta’s sites have strong data analytics teams to identify opportunities for efficiency gains and continuous improvement.

Reflecting on the gradual rollout of automation across the company’s operations, Muchnik referred to the overarching roadmap the company outlined in 2017.

“This roadmap considered different strategic programs with rollout options that improve productivity and safety, with automation being a relevant dimension,” he said. “It was built on the concept of knowledge transfer to enable other companies of the group to benefit and learn from the experiences at specific sites.”

That has worked from the looks of it, going from Epiroc Pit Viper autonomous drill deployments at Los Pelambres to the rollout of the technology at Esperanza Sur (part of Centinela).

A fleet of 11 autonomous electric drive Komatsu 980E-5 trucks have also gone live at Esperanza Sur over this time frame.

“Another good part of that is the Integrated Remote Operating Centres (IROC) we have setup to support these operations,” Muchnik said. “We recently opened an IROC for Centinela in the city of Antofagasta and, following the same transfer process, Los Pelambres is expected to go live with their IROC here in Santiago, in the second half of 2022.”

Integrated Remote Operations Centre for Centinela, based in the city of Antofagasta

Muchnik says one of the many benefits of the IROCs is the ability to attract and retain talent for Antofagasta’s operations.

“It is not just about bringing in new talent but working with our people to be allow them to move with this transformation and become digitally literate to help us prepare for an autonomous and remotely-operated future,” he said.

An in-house digital academy that Muchnik and his colleagues launched in 2020 has been vital in this process.

“It has enabled a different mindset within our workforce, preparing them for the transition through training and learning.

“This has ensured all of our employees go through the journey with us.”

Yanmar strives for smart electrified systems integrator status at Bauma 2022

Yanmar, a provider of power solutions and industrial machinery, is introducing its electrification strategy for off-road vehicles and equipment at Bauma 2022, in Munich, Germany, the world’s biggest construction equipment exhibition.

Yanmar will showcase its off-road product portfolio, commitment to customer lifecycle value and future vision for industrial equipment, including the following highlights:

  • Electrification strategy for e-powertrains;
  • Electric equipment demonstrator;
  • Yanmar/ELEO modular, high-density battery system; and
  • Extended five-year warranty for TN Series engines

Yanmar will establish itself as the all-in-one systems integrator for smart electrified power solutions tailored to the application-specific needs of individual OEMs, it says. In its capacity as a systems integrator, Yanmar will implement system engineering, design and manufacturing of e-powertrains, while also providing control development, system evaluation, procurement, manufacturing and quality assurance.

Tomohisa Tao, President Yanmar Power Technology Co. Ltd, said: “As Yanmar looks to meet the challenges of the coming century, our transformation will encompass new products with alternative fuel technologies. Our aim, together with our dealers and OEM partners, in this strategy is to build stronger relationships and create even greater customer value with new-energy technology. We will work hard to support our OEM partners and customers to achieve their environmental and performance goals.”

At Bauma 2022 on October 24-30, Yanmar will show an electrified demonstration vehicle that shows the practical application of the company’s system integrator technologies. Powered by an efficient electric drive and hard working 48 V batteries with fast charging capability, the electric excavator is a quiet, zero-emission machine designed to meet the most demanding emissions restrictions.

An important milestone for realising the urgent environmental challenges that must be overcome is Yanmar’s acquisition of battery-technology company ELEO, a fast-growing developer and manufacturer of high-performance modular battery systems. This acquisition will further Yanmar’s electrified powertrain capabilities with versatile, customised solutions for off-road applications. ELEO is building a new battery production plant, increasing its annual battery production capacity tenfold to 500 MWh – the equivalent of approximately 10,000 battery packs.

The company is also launching a new 5-year warranty (or 5,000 hours) offer, further enhancing sustainability and extended ownership of the current line-up of clean diesel solutions during the transformation to carbon-neutral power solutions, it says. This extended warranty is free of charge and valid for TN Series engines sold in Europe and operating on European territory.

Yanmar says it has already embarked on several new-energy projects in various business lines, including hydrogen-powered co-generation, research into hydrogen fuel marine engines, bio-gas cogeneration, dual-fuel power solutions with natural gas, fuel cell marine technology, smart agriculture and resource recycling technologies.

Seabridge Gold weighs automation and trolley assist haulage for KSM project

Automation, Base metals, Environmental, Mineral project development, Mining equipment, Mining services, Power supply for mines, Precious metals, , , , , , , , , ,

Seabridge Gold has completed an updated prefeasibility study for its KSM Project in British Columbia, Canada, that focuses on open-pit mining only, while planning for both autonomous mine operations and trolley assist haulage.

The 2022 PFS, prepared by Tetra Tech, shows a considerably more sustainable and profitable mining operation than its 2016 predecessor, now consisting of an all open-pit mine plan that includes the Mitchell, East Mitchell and Sulphurets deposits only, it said.

The primary reasons for the improvements in the plan arise from the acquisition of the East Mitchell open-pit resource and an expansion to planned mill throughput – to 195,000 t/d, from 130,000 t/d, the company said.

The many design improvements over the 2016 PFS include a smaller environmental footprint, reduced waste rock production, reduced greenhouse gas emissions, a 50% increase in mill throughput and the elimination of capital-intensive block cave mining, it added.

While total capital has been reduced to $9.6 billion (from $10.5 billion) – with increases from inflation and mill expansion being wholly offset by the elimination of block cave mining from the PFS plan – the initial capital cost has increased to $6.4 billion (from $5 billion) due to inflation.

Life of mine production (33 years) at KSM consists of 1.03 Moz of gold, 178 MIb (80,739 t) of copper, 3 Moz of silver and 4.2 MIb of molybdenum.

The open-pit-only mine production plan using ultra class mining starts in the higher grade Mitchell pit, Seabridge Gold says.  Production from the high grade upper East Mitchell zone is introduced in Year 3. Waste mined from the Sulphurets, East Mitchell and Mitchell pit is placed in the Mitchell rock storage facility (RSF) until Mitchell pit is mined out by Year 25. Final waste from East Mitchell is backfilled into the mined-out Mitchell pit from Year 25 onward along with some waste rehandled from the Mitchell RSF.

Autonomous mine operations where applicable and an integrated remote operations centre reduce on-site personnel, the company noted, while adding that electrification of the haul truck fleet with trolley assist would reduce carbon emissions and overall mine energy costs by replacing diesel with low-cost energy from electricity.

EU competition, collaboration and connections helping Epiroc solve mining challenges

Epiroc’s start-up mentality is enabling it to continue to solve the mining industry’s biggest challenges, but it is not doing this alone, according to Katarina Öquist, R&D Manager of Technology and Innovation in the Underground Division.

Speaking ahead of her appearance at the EIT Raw Materials Summit 2022 in Berlin, Germany – taking place on May 23-25 – Öquist said access to other industry partners, academic institutes and start-ups through initiatives like EIT Raw Materials continues to help the company overcome challenges the sector throws at it.

“Specifically on the EIT Raw Materials project, there is the possibility to take in young start-ups and academic institutes, which can prove key when considering the ‘kicks‘ the funding can provide such companies and initiatives,” she said. “It is important for these young technology companies to have a connection to applications, being able to test out concepts and ideas in a real-world environment with companies like Epiroc, and, at the same time, introduce new thinking into industries such as mining.”

This wide scope of participation is increasingly required when considering the future direction of the mining industry, according to Öquist.

Katarina Öquist, R&D Manager of Technology and Innovation in Epiroc’s Underground Division

“If you look at the mining industry, and the part I am in with Epiroc, we are experiencing the biggest technology shift ever,” she said. “We are looking at electrification, autonomy and digitalisation all at the same time. All of these have interdependencies and connections in between, which make it quite complicated.

“When I started in the start-up sector some 15 years ago, you often were looking to solve one problem, but, today, you are not offering the sole solution; you must interact with a much bigger technology ecosystem.

“For this, collaboration is very important.”

In this regard, EIT Raw Materials and European Union Commission funding are more important than ever, ensuring all stakeholders are connected and focused on coming up with workable solutions for industry to achieve their lofty ambitions.

While not tied to EIT Raw Materials, the NEXGEN SIMS project is a good example to highlight here.

NEXGEN SIMS builds on the EU-sponsored SIMS (Sustainable Intelligent Mining Systems) project, which aimed to demonstrate new technology and solutions for the mining industry. Running from 2017 to 2020, the SIMS project resulted in, among other things, the Epiroc line of battery-powered mining machines.

NEXGEN SIMS, meanwhile, is a consortium of 13 partners collaborating in an EU-sponsored project to develop autonomous, carbon-neutral, sustainable mining solutions, building on the SIMS success. The partners are Epiroc Rock Drills, AFRY – ÅF Digital Solutions, Agnico Eagle Finland, Boliden Mineral, Ericsson, KGHM Cuprum, KGHM Polska Miedź, K+S Minerals and Agriculture, Luleå University of Technology (LTU), LTU Business, Mobilaris MCE, OZ Minerals and RWTH Aachen University. The project, led by Epiroc, has a budget of €16 million ($16.8 million) and will run from May 2021 to April 2024.

“In the case of NEXGEN SIMS, it is built on a known partnership including new partners,” Öquist said. “After being involved with the majority of these partners since SIMS, we build from a high level of trust, which increases the possibility of success, especially concerning integration.

“Europe, in general, is very good in facilitating these type of collaborative projects that involve all segments of the innovation ecosystem – start-ups, industry partners and academics.”

According to Öquist, the NEXGEN SIMS project remains on track, with the integrations between electrification, automation and digitalisation likely to hold the most exciting outcomes for the wider mining industry.

For its part, Epiroc is also helping accelerate the development of start-ups of its own, taking stakes/interests in key technology providers and allowing them access to its much larger network.

ASI Mining, FVT Research and Mining TAG represent just a few examples here.

Öquist expanded on this with a reference to Mobilaris MCE, a company Epiroc acquired outright just last year, after five years of holding a 34% stake.

“They (Mobilaris MCE) started off in 1999 as a start-up from the telecoms business,” she said. “Due to them being in the northern part of Sweden, they tagged onto the mines and we ended up acquiring a minority interest in them.

“In the five years since, they have had a nice journey under the guise of Epiroc. They represent a local small start-up growing by going under the wings of a much larger industry partner.”

Epiroc, too, has benefitted from this collaboration, with Mobilaris MCE’s situational awareness technology recently becoming a key part of the OEM’s 6th Sense digital solution.

Not all OEMs would be willing to facilitate the growth of other companies in such a way, but Öquist, who has only been in her role with Epiroc for two years, puts this down to the company‘s unique culture.

“We call ourselves a 150-year-old start-up,” she said. “Regardless of how big we grow, that mindset remains – if someone highlights a problem, we set out to solve it through both internal and external collaboration.”

Sandvik introduces new electric concept surface drill rig to the industry

Sandvik Mining and Rock Solutions says it is bringing a ground-breaking electric concept drill rig for surface drilling to the Vei og Anlegg 2022 exhibition, with the potential for this solution to impact larger, mining-related drilling operations in the future.

Taking place on May 11–14, 2022, Vei og Anlegg is one of Scandinavia’s largest construction trade shows.

The new concept rig demonstrates some of the advanced technologies that will be introduced on future series drill rigs to support more sustainable and energy-efficient surface drilling, particularly in urban construction applications, it said.

The concept drill rig is essentially a versatile R&D platform for demonstrating the most advanced, but nevertheless proven and validated, sustainability technologies that are already in use or coming soon on underground drill rigs and loaders. The innovation lies in transferring these technological advantages into the surface drilling world for the first time to meet the latest demands from the industry, Sandvik says. The concept drill rig brings the new solutions together on an actual machine that you can get up close to – a “hands on” starting point for discussions on the customer’s real-life needs and the technological possibilities for addressing them with tomorrow’s products.

Builders and contractors are increasingly faced with specific, often quantified, sustainability targets: for example, electrification of power supply, energy efficiency targets and exhaust/noise restrictions. Sandvik says it wants to lead the way with the concept drill rig, demonstrating effective sustainability solutions that are designed to meet these challenges. The technologies demonstrated on the rig include electrified power supply and a range of emission reduction technologies, with the overall aim of energy efficiency and emission control (noise, particulates and CO2).

The compact Commando™ DC300Ri top hammer drill rig was selected as the platform for the concept drill rig, thanks to its popularity in urban surface drilling applications (for example, road/railroad construction and foundation drilling). It is however possible that product development projects based on the concept rig may lead to different, possibly larger, drill rigs. The concept rig also has the possibility of operating on direct electric power or battery power, as well as hybrid power supply using a small diesel generator. All of these energy sources are available and can be trialed on the concept drill rig, depending on the customer’s actual needs. The rock drill is also equipped with an effective noise guard.

“We could make the selections ourselves, for example the choice between a direct electric power supply and a battery-driven system, but we want to do it together with our customers,” Lauri Laihanen, Vice President, R&D and Product Management, Surface Drilling Division at Sandvik, said. “We want to have a dialogue, to ensure we really understand the customer’s actual needs and are tackling the right problems together. It’s about customer orientation, rather than technology orientation. Technology for us is only a tool to meet the customer’s needs. With this concept drill rig, the primary role of technology is to support a zero emissions approach at the customer’s operations, which of course aligns perfectly with Sandvik’s own sustainability goals.”

Alongside the market-oriented goals, the concept drill rig will also help Sandvik to achieve its own ambitious sustainability goals, including its aim to halve the carbon footprint of the group’s operations by 2030.

The conversation on the future of sustainable surface drilling is now underway and the next chance to see the concept drill rig, following Vei og Anlegg, will be in Tampere, Finland, at Sandvik Mining and Rock Solutions’ Customer Days 2022 in September.

Newmont has announced a strategic alliance with Caterpillar Inc to deliver a fully connected, automated, zero carbon emitting, end-to-end mining system that will see the introduction of first-of-a-kind battery-electric haulage technology and automation at the gold miner’s Cripple Creek and Victor and Tanami mines in the USA and Australia, respectively.

The announcement comes a day after Newmont’s Executive Vice President and Chief Technology Officer, Dean Gehring, told the Energy and Mines Virtual World Congress that the company’s primary focus for decarbonising its mobile mining fleet was on battery-electric options. It also follows the deployment of autonomous haulage solution technology at the Boddington mine in Australia (control room, pictured).

Together, the two companies will collaborate to create a safer, more productive mine, and substantially support Newmont in reaching its 2030 greenhouse gas (GHG) emissions reduction targets of more than 30%, with an ultimate goal of being net zero carbon by 2050, the companies said.

Tom Palmer, President and CEO of Newmont Corporation, said: “A year ago, Newmont announced industry-leading emission reduction targets because we understand the human contribution to climate change. We followed with a commitment to invest $500 million over five years to identify pathways forward as we firmly believe that we must make bold, lasting commitments to achieve the necessary change for a bright, healthy future.

“Today, we furthered that commitment by announcing a new strategic alliance with Caterpillar to address climate change by fundamentally changing the mining industry through the rapid development and implementation of a comprehensive all-electric autonomous mining system to achieve zero emissions mining.”

Newmont’s surface and underground mining fleets are responsible for approximately 40% of the company’s carbon emissions, and building a new model for surface and underground mining is critical to delivering on Newmont’s emissions reduction targets, the company said.

Newmont will also be supporting Caterpillar’s validation of evolving features and functionality within the MineStar suite to be deployed across Newmont’s surface and underground assets globally. This deployment facilitates centralised production and asset management.

“Caterpillar is committed to providing transformational advancements in safety, sustainability and technology,” Jim Umpleby, Chairman and CEO of Caterpillar Inc, said. “We share Newmont’s dedication to a reduced-carbon future, and we’re honoured to work together on this industry leading effort.”

Under the agreement, Newmont plans to provide a preliminary investment of $100 million as the companies set initial automation and electrification goals for surface and underground mining infrastructures and haulage fleets at Newmont’s Cripple Creek and Victor (CC&V) mine in Colorado, USA and Tanami mine in Northern Territory, Australia. The goals include:

  • Introduction of an automated haulage fleet of up to 16 vehicles at CC&V planned through 2023, with a transition to haulage fleet electrification and implementation of Caterpillar’s advanced electrification and infrastructure system with delivery of a test fleet in 2026. Actions include validating first-of-a-kind battery-electric haulage technology in the years prior to full production of autonomous electric haulage equipment;
  • Caterpillar will develop its first battery electric zero-emissions underground truck to be deployed at Tanami by 2026. The deployment includes a fleet of up to 10 battery-electric underground haul trucks, supported by Caterpillar’s advanced electrification and infrastructure system. This includes first-of-a-kind battery electric haulage technology for underground mining in 2024, the introduction of battery autonomous technology in 2025, with full deployment in 2026.

Together, Newmont and Caterpillar plan to validate equipment, infrastructure, technologies and processes to transform both surface and underground mining, focusing on safety, automation, decarbonisation, optimisation, data and asset management across Newmont’s global operations, the miner said.

“Leveraging Newmont’s scale and operational capabilities, the alliance sets the stage for the rapid development and deployment of the technologies, ultimately improving safety, productivity and energy efficiency across the mining industry,” it added.
