Sandvik to supply battery-electric vehicle fleet to Hindustan Zinc’s SK Mine

Sandvik and Hindustan Zinc have signed a Memorandum of Understanding for supply of a battery-electric underground equipment fleet to be used at Sindesar Khurd Mine to help it achieve its carbon neutrality ambitions.

Deliveries are scheduled to begin in the March quarter of 2023, with the fleet being the first underground battery-electric fleet to be deployed in India.

The equipment to be delivered includes an 18-t-payload LH518B loader and three 50-t-payload TH550B trucks (pictured) as well as a DD422iE drill rig with Sandvik’s unique and patented ”charging-while-drilling” technology, the company said.

Sandvik will also provide batteries, charging systems and a full-range on-site battery and equipment service team. The loader and the trucks will be equipped with AutoSwap, Sandvik’s patented battery self-swapping system, capable of battery changeout in a few minutes.

“Aligned with our expansion strategy for battery-electric vehicles, I’m delighted to sign this agreement with Hindustan Zinc to deliver the first battery equipment fleet in India,” Henrik Ager,  President of Sandvik Mining and Rock Solutions, said. “This is a testament to both the pioneering ambitions of Hindustan Zinc and the technological maturity of Sandvik BEV products.”

The TH550B truck and LH518B loader are based on the Artisan™ technology, which Sandvik acquired in 2019, and enriched with the latest Sandvik mining technology, contributing to overall productivity improvements of up to 20%, the OEM said. The machines will be equipped with state-of-the-art battery telemetry solutions enabling automated, on-premise as well as remote health and performance monitoring.

The Artisan driveline and battery solutions have been field tested with more than 500,000 operating hours.

Sandvik outlines its emission-free mining journey at The Electric Mine 2022

Sandvik Mining and Rock Solutions President, Henrik Ager, got The Electric Mine 2022 Conference in Stockholm, Sweden, off to a bang earlier this month, with a major product reveal that will set a new benchmark in the battery-electric underground mining space.

After reflecting on a journey that saw him escape a broken lift on his way to the Radisson Waterfront that morning, Ager announced the company would soon release the largest-capacity battery-electric truck for underground mining to the market, the TH665B.

With a 65-t-payload capacity, this machine will be measured against the largest underground diesel-powered underground trucks for productivity, speed and cost. Interest is expected from major contractors and miners alike, with one of the bigger markets being the Australian underground hard-rock segment.

The prototype TH665B is currently completing factory testing, but it turned heads in Stockholm, with conference attendees witnessing a video of the machine in action on the company’s test track in California, USA.

Blending proven Sandvik design and advanced technology built around electric drivelines and battery systems, the TH665B will get its first mine site runout at AngloGold Ashanti’s Sunrise Dam gold mine in Western Australia. This trial is expected to prove its viability in a long ramp haulage application before commercial truck production commences in late 2023.

The Sandvik TH665B comes with an electric drivetrain that delivers 640 kW of continuous power, which equates to 858 horsepower

While displaying said video, Ager said the vehicle could haul a 65-t load up a 14.3% grade at 11.5 km/h. This, he said, was 30% faster than Sandvik’s 63-t diesel truck, the Toro TH663i, with which the TH665B shares a state-of-the-art cabin. An electric drivetrain that delivers 640 kW of continuous power, which equates to 858 horsepower, and significant torque, is behind such numbers.

Following the introduction of the Sandvik TH550B 50-tonne battery-electric vehicle at MINExpo INTERNATIONAL® 2021, last September, this latest vehicle launch shows, once again, how the company is betting big on its battery- and hybrid-electric loaders tackling the challenge of operating underground mines today and tomorrow.

Ager at the event outlined the three main drivers for the electrification move, namely: worker health, mine economics and sustainability. Sandvik’s battery-electric solutions, he said, hit all three criteria, providing safer, more productive and sustainable ways of moving the tonnes the industry needs to keep up with global commodity demand.

The primary driver for electrification came from ventilation and refrigeration constraints, followed closely by environmental, health and safety concerns over diesel exhaust emissions. At the same time, Ager said there was significant room for operating costs to fall with the adoption of battery-electric equipment given 40% of total mine operating costs were related to energy and ventilation, and electricity use was often cheaper than transporting and using diesel fuel underground.

Around the same time as MINExpo, Ager outlined that electric mining equipment could account for more than half of the company’s equipment sales in underground mining by 2030. In Stockholm, he added some colour to that statement.

The company’s generation three battery-electric vehicles have clocked up more than 500,000 operational hours with its Artisan™ battery packs and electric drivelines, with 22 active BEV units. This experience makes Sandvik an industry frontrunner, Ager said.

The machines out in the field include the 4-t-payload and 10-t-payload Artisan A4 and A10 LHDs, the Z40/Z50 (40 t/50 t payloads) haul trucks, the Toro™ LH514BE – an AutoMine®-compatible cable-electric loader, boosted with battery technology – plus the 18-t-payload battery-electric Sandvik LH518B LHD and 50-t-payload battery-electric TH550B truck.
This year will see the company officially release the LH514BE, which will be followed in 2023 by the TH665B and – judging from the preliminary nomenclature – a 15 t battery-electric and AutoMine-compatible LHD.

Three other battery-electric and AutoMine-compatible units are in the preliminary stages of development, scheduled for release in 2024-2025.

This comes on top of plans to electrify its full i-Series drilling line by 2030, drill rigs which tram on battery and plug into the grid while drilling/bolting.

Launches for the DD422iE-DC (development drill) and DS422iE (rock bolter) are expected in 2022, with the DL432iE (longhole drill) and the DT923iE (jumbo drill) coming to market between 2023 and 2026.

Since the rollout of the first battery-electric drill in 2016 – the DD422iE – 2.8 million metres had been drilled and 12,500 km had been trammed with these electric machines, Ager acknowledged.

It is not just product releases that are on the Sandvik roadmap, with Ager stating plans to develop different drivelines (battery-electric, hybrids, cable, battery-cable), quantify the value and beat the economics of conventional drivelines, expand into other applications such as narrow vein and narrow reef mines, and continue to develop 100% electrified, energy efficient mechanical cutting for soft- and hard-rock applications.

He also said the company would look to address the capital expenditure gap with diesel machines, aiming for cost parity from a total cost of operations perspective.

The company, at the same time, is planning to further its global capabilities to serve the electrified fleet throughout its entire life cycle, while building out battery optimisation expertise and developing global application knowledge to support customers in designing, planning and executing electric transition strategies.

Real equipment for the real world

This might look like a long ‘to-do’ list, but Ager’s colleague, Brian Huff, VP of Technology and Product Line for the BHEV business unit with Sandvik Mining and Rock Solutions, was able to outline several real-world wins from machine deployments later at the conference that showed how far the company has already come in addressing industry pain points.

Huff, a co-founder of Artisan Vehicle Systems, relayed some observations from field trials of the company’s LH518B and Z50 battery-electric vehicles, summing them up in series of snappy statements such as: “everything will be serviced, whether it was intended to be or not”; “battery cells are consumable, but the driveline is not”; “damage is expected, resilience and serviceability are required”; “isolation fault monitoring is more than shock hazard prevention”; “availability improves with each ‘opportunity’”; and – one of the more important ones – “operators prefer BEVs”.

“They take a beating and keep on working and, despite what people may think, these batteries are not fragile,” Brian Huff told delegates at The Electric Mine 2022 Conference earlier this month

Delving into specifics, Huff said real-world trials had proven the opinion that electric drivelines came with dramatically longer life and less maintenance. He also acknowledged batteries had become the new ‘consumable’ in this equation.

“Maintenance requires parts, but comes with very low labour,” he said, explaining that battery modules can be replaced underground and then rebuilt at the factory with new cells, making rebuilds both quick and painless. At the same time, refreshing the battery brought opportunities to use improved cells as they are developed – a reflection on the accelerated winds of change in the battery market.

Battling early market perceptions, Huff said these machines were far from “experimental”, having been used and proven to work at many hard-rock mines. “They take a beating and keep on working and, despite what people may think, these batteries are not fragile,” he said.

One of the new solutions to have come out from these real-world trials is the introduction of a new battery cage design that aids serviceability, Huff said. Coming with removable side covers, an improved locking system and structural design, this battery cage incorporates the company’s AutoConnect function, which, when combined with AutoSwap, facilitates quick battery swapping without the operator having to leave the cabin. The new cage would be available on the TH665B as well as other models, Huff said.

He then put some names and numbers behind earlier statements, highlighting a trial of a Z50 truck at Pretivm’s Brucejack gold mine in British Columbia, Canada, that saw more than 90% machine availability, exhibited speeds of 9.5 km/h on a 15% grade with a 42-t load, and observed battery swap times of less than 10 minutes. This added up to a 42% increase in tonnes hauled compared with a diesel-equivalent machine and a 22% boost in speed.

The trial at New Gold’s New Afton gold mine, also in British Columbia, saw a 56% mucking cycle time beat over a diesel-powered-equivalent, a plus-70% ramp speed improvement (on a 17% ramp), and decreases of 80% and 90% in energy use and heat generated, respectively.

Referring to another LH518B trial where the machine only clocked in a 74.9% availability, Huff was quick to highlight that all the problems/failures that caused the reduction in availability were correctible.

And, channelling his engineering DNA and the leading role Sandvik is willing to take in the industry’s pursuit of the zero emission, electrified mine, he reflected on all these real-world trials with: “a failure isn’t a failure, it is an opportunity to improve.”

Sandvik receives record AutoMine order from Codelco’s El Teniente mine

Sandvik Mining and Rock Solutions says it has received a major order for the AutoMine® load and haul automation system valued at about SEK 250 million ($28 million) from Chile’s Codelco to be used in the El Teniente mine.

In addition, a connected load and haul equipment order, with an initial value of SEK 150 million, was received, bringing the total value of the orders to SEK 400 million, Sandvik said.

The contract will run from 2022 through 2027 at the Andes Norte block cave.

Since the first AutoMine system was commissioned in El Teniente’s Pipa Norte mine in 2004, Sandvik has supplied several intelligent load and haul equipment fleets as well as AutoMine and OptiMine solutions to Codelco mines.

The new order will be supplied in two phases. During 2022 and 2023, Codelco will receive two Toro™ TH663i trucks and two Sandvik LH514 loaders, as well as an AutoMine Fleet system capable of being scaled to support up to 16 machines and AutoMine production area hardware for future expansions over several years.

The first phase of the order, which also includes support contracts for the equipment and AutoMine system, will initially be used by Codelco Andes Norte in a new block caving area in El Teniente that is expected to commence production between mid-2022 and early 2023.

From 2023 through 2027, Sandvik will deliver six more Toro TH663i trucks, six Sandvik LH514 loaders and an additional AutoMine Fleet system.

Emilio Vega, Business Line Manager for Automation, Sales Area Andean & South Cone at Sandvik Mining and Rock Solutions, said: “Codelco selected Sandvik’s solutions based on our proven technology, capable of fulfilling requirements for safety, reliability and productivity. Furthermore, we have competent staff capable of serving and supporting the organisation’s existing systems. This provides value-added services that enable optimised productivity in order to meet the customer’s production performance.”

AutoMine underground for loading and hauling is an automation system for autonomous and tele-remote operation of a wide range of Sandvik loaders and trucks. The scalable solution can provide tele-remote to fully autonomous operation for a single machine or multiple machines, including full fleet automation with automatic mission and traffic control capability, according to Sandvik.

Patricio Apablaza, Vice President Sales South Cone & Andean at Sandvik Mining and Rock Solutions, added: “Codelco’s objective is to continue implementing automation and digitalisation solutions in its mining operations. We have a great opportunity, as a key supplier, to be part of this change by supporting Codelco with high-end technology and providing key support to its operations to help our customer succeed in this journey.”

The AutoMine Fleet system is a highly advanced automation system for a fleet of Sandvik underground loaders and trucks sharing the same automated production area. It provides advanced traffic control capabilities, as well as a wide range of interfaces for infrastructure integration to allow for complex automation applications in challenging environments.

Pablo Gandara, Project Portfolio Manager, El Teniente Mine, explained: “For Codelco and, in particular, for El Teniente mine, it is a goal to continue being the largest underground mine in the world. This purpose also needs to be accompanied by other attributes that are key today to continue being leaders in the mining business, such as safety, environmental sustainability, and productivity.

“Considering all these elements, we have come to the conclusion that to operate our mines we require companies that have the same values, and that is how we came to define that the Sandvik AutoMine product satisfies all our needs. In addition to show best practice of a real partnership is the cooperation that began many years ago between Codelco and Sandvik in the first automated project for El Teniente, which was the Pipa Norte sector in 2004. From there we have built a relationship between two companies, we understand each other very well, and we trust in the joint capacities that we have developed.”

David Hallett, Vice President, Automation at Sandvik Mining and Rock Solutions, said: “We are excited to continue our journey in automation and digitalisation at Codelco’s El Teniente mine to help increase safety and productivity for their operations. This order will be delivered as a turnkey solution composed of all elements of Sandvik Mining and Rock Solutions’ offering for equipment, digital technologies and aftermarket. Sandvik strives to be the number one productivity partner for our customers and this order and delivery will embody all elements of this.”

Back in February 2021, Sandvik said it would deliver its AutoMine Fleet system to automate a new fleet of Sandvik LHDs running at Codelco’s Pacifico Superior and Pilar Norte GTI operations, part of the El Teniente underground mine.

Sandvik to acquire Deswik and form new Digital Mining Technologies division

Sandvik has signed an agreement to acquire Deswik, a provider of mine planning software, with plans for the Australia-based company to be part of a newly formed Digital Mining Technologies division within the Sandvik Mining and Rock Solutions business area. 

By acquiring Deswik, Sandvik gains a top-tier supplier of integrated software platforms that, it says, support digitalisation throughout mine planning stages, with more than 10,000 current licences.

Deswik has a high quality customer base, and its strong profitable growth and low customer churn will further enhance Sandvik’s presence within software and digitalisation, and help accelerate growth, the company added.

I am very pleased that we continue to execute on our shift to growth strategy, and continue to broaden our offering with digital solutions that increase productivity in the customers value chain,” Stefan Widing, President and CEO of Sandvik, said. “Mine planning and operations management is a key growth opportunity, and this complementary acquisition and our new Digital Mining Technologies division will strengthen our digital offering and enable us to provide customers a more comprehensive suite of technologies.

Deswik will fill a value chain gap in Sandvik Mining and Rock Solutions’ offering, increasing upstream mining coverage and enabling opportunities for end-to-end optimisation solutions, including, for example, incorporating electrification at the mine planning stage, the company explained.

Henrik Ager, President of Sandvik Mining and Rock Solutions, added: Deswik’s second-to-none software suite combined with Sandvik’s digital and automation offering creates a clear world leader in digital solutions for the mining industry. Combining Deswik’s skills in mine planning and scheduling with our equipment and automation expertise will open new opportunities for optimising our customers’ mining value chain.” 

Deswik will form one of three cornerstones in the newlycreated Digital Mining Technologies division, established to, the company says, accelerate the execution of Sandvik Mining and Rock Solutions strategic priority to lead the industry development of underground sustainability and productivity solutions in electrification, automation, digitalisation and end-to-end optimisation. The new division also includes Sandvik Mining and Rock Solutions automation solutions and the Newtrax telemetry and collision avoidance solutions.

Privately-owned Deswik, established in 2008 and headquartered in Brisbane, has approximately 300 employees and operates 14 offices in 10 countries. Deswik’s revenue as of October 2021, on a rolling 12-month basis, totalled A$79 million ($56 million), of which the share of recurring revenue was approximately 45%, and with an EBITA margin of approximately 30%.

The transaction is expected to close during the March quarter of 2022, subject to relevant regulatory approvals. Sandvik estimates that transaction costs of approximately SEK50 million ($5.5 million) in total will impact Sandvik Mining and Rock Solutions in the December quarter.

Sandvik reinforces rock tools offering with Tricon Drilling Solutions acquisition

Sandvik has signed an agreement to acquire Tricon Drilling Solutions Pty Ltd, a privately-owned supplier of rock tools for the mining industry, based in Perth, Australia.

Tricon will operate as an independent, standalone business unit within the Rock Tools division of Sandvik Mining and Rock Solutions.

Tricon’s product offering includes rotary bits, DTH (Down-The-Hole) hammers and bits, as well as full rotary and DTH drill strings. The company has 24 employees.

“I am pleased that we continue to deliver on our active acquisition agenda, and I look forward to welcoming Tricon to Sandvik,” Henrik Ager, President of Sandvik Mining and Rock Solutions, said.

Tricon has design capabilities for rotary bits in-house but outsources manufacturing, with Sandvik being one of its rotary bit suppliers. Drill string products are produced in Tricon’s own facility.

The acquisition is expected to close in the September quarter of 2021, subject to relevant regulatory approvals.

Sandvik reinforces underground mining safety focus with DSI Underground buy

Sandvik has signed an agreement to acquire DSI Underground, a global leader in ground support and reinforcement products, systems and solutions for the underground mining and tunneling industries, from owner Triton.

The OEM has agreed a purchase price of approximately €943 million ($1.15 million) on a cash and debt free basis, it said, adding that the company will be reported in the Sandvik Mining and Rock Solutions division.

Stefan Widing, President and CEO of Sandvik, said: “This acquisition is an important step in our growth ambition. DSI Underground’s track record of driving progress and safety in underground operations and its global reach will further strengthen our world-leading market position within mining and rock solutions.”

DSI Underground is present in 70 countries, with 22 production units situated close to end customers, according to Sandvik. The product offering includes bolting systems, injection chemicals and resin capsules.

Henrik Ager, President of Sandvik Mining and Rock Solutions, added: “With the world’s most extensive choice of ground support products and systems, DSI Underground’s offering is highly complementary and enables us to deliver greater value and safety to our customers. The deal gives DSI Underground access to Sandvik’s substantial R&D, global service and sales network, complements our growing aftermarket business and strengthens our leadership in underground mining and tunnelling.”

The transaction is expected to close by mid-2021 and is subject to relevant regulatory approvals.

Tackling the big mine electrification questions

“There is consensus in the industry that once we start doing electrification, we will innovate much more in other areas of the mining space.”

If anyone in the mining sector thought electrification was not in their wheelhouse, Theo Yameogo’s words might make them think again.

Yameogo, Partner and National Mining & Metals Co-Leader at EY Canada, made such a statement during The Electric Mine Virtual Conference earlier this week. The event, organised by International Mining Events, brought leaders in the electrification space together to discuss the latest developments in the industry, of which there were many.

The stage was set for mine electrification reveals, and Henrik Ager, President of Sandvik Mining and Rock Technology (soon to be Sandvik Mining and Rock Solutions), did not disappoint, acknowledging that the company is currently working on development of what would be its largest underground truck: a battery-powered 65 t vehicle.

This was all part of the company’s aim to have a “full range electrified offering by 2022”, he said.

Azizi Tucker, Co-Founder and CTO of XING Mobility, was next up, providing an overview of the Taiwan-based company’s offering in his presentation: ‘Electrification from prototype to mass production’.

With a remit to provide commercial, industrial and specialty vehicle makers with modular, high power and safe battery and powertrain technologies, XING is making an entrance into the mining space at just the right time.

Tucker talked attendees through the elements that make the company’s IMMERSIO™ battery solutions ideal for the mining sector: “With the modular size and shape of our batteries, we can really suit any vehicles. We find this very popular with the original equipment manufacturers (OEMs) as they can utilise their existing chassis.”

The elimination of corrosion, ability to operate consistently in high-temperature environments, a variety of sealing techniques and the use of nickel-manganese-cobalt lithium-ion chemistry has allowed the company to provide the safe and enclosed battery solution miners are looking for.

He concluded by saying XING was in conversation with a variety of mining companies, mining OEMs and mine site operators about deploying solutions in the space.

Attendees were then treated to a demonstration of Tembo 4×4 e-LV’s Electric Cruiser via video during the session: ‘Green conversions: the Tembo 4×4 e-LV electric light utility vehicle platform’ (pictured below). They got up close and personal with the battery-electric utility vehicle as it travelled on- and off-road close to the company’s Netherlands HQ.

After a 15-minute demo showing off the Electric Cruiser’s attributes, Paul Smeters, Tembo 4×4 e-LV’s Marketing Manager, and Alexander Haccou, Tembo 4×4 e-LV’s Technical Director, joined the event to answer audience questions.

The inevitable query came up early during the live Q&A: have you tested this vehicle in an underground mine?

Haccou was prepared for this, explaining that Boliden’s Tara underground zinc-lead mine in Ireland was the first recipient of the company’s Electric Cruiser, and a unit had been operating there for a few years now observing many of the maintenance benefits battery-electric machines are becoming renowned for.

The Electric Cruiser has also been tested in Australia and Canada with the help of Tembo 4×4 e-LV partners in those regions, he added.

“We don’t use fast charging or battery swapping,” Haccou said in response to another question. “What we have seen in several mines is the daily amount of usage is less than the battery’s full capacity.”

After several questions related to an active thermal management system for batteries had come up in previous sessions, Nicolas Champagne’s entrance to the virtual event proved timely.

His presentation, ‘Battery thermal management system using a highly advanced dielectric fluid’, homed in on the use of a dielectric fluid with specific features to allow direct cooling of the battery electrochemical cells.

Champagne, Formulation Team Manager of the R&D department for TOTAL Lubricants, revealed results from use of the fluid in bench tests and simulations at the battery pack level, extrapolating what these results could mean for battery-powered vehicles in the mining sector.

He said the company is in discussions with at least one mining customer about deploying its fluid on a battery-powered vehicle.

After previous sessions had discussed the potential for fast charging and battery swapping, Champagne made clear that TOTAL Lubricants’ solution would prove beneficial in all battery-powered applications throughout the mining sector.

 

Following a lunch break, it was the turn of Epiroc’s Anders Hedqvist (Vice President of R&D, underground) and Franck Boudreault (Electrification Transformation Lead, underground) to deliver a scoop (pun intended).

The pair, during their presentation, ‘From one generation to the next – learnings from zero emission mining’, took it in turns to provide updates.

Boudreault revealed the company’s plan to create battery-electric conversion kits for not only Epiroc diesel-powered equipment out in the field but other OEMs’ machines, before Hedqvist disclosed the company’s in-development battery-electric 18 t LHD would be trialled at LKAB’s Sustainable Underground Mining (SUM) project in Sweden. Epiroc has already delivered a diesel-powered Scooptram ST18 to be trialled in autonomous mode at the SUM project.

It was Yameogo, a mining engineer with much experience operating in underground mines in Canada, that provided the event’s big picture talk in his presentation, ‘Will electrification spark the next wave of mining innovation?’

He talked up the need for industry collaboration between miners, OEMs and service providers in not only electrifying equipment and operations, but also other types of technology.

“That type of collaboration and co-creation framework will actually help mining companies also think about innovation and other items part of electrification and equipment, in general,” he said.

The focus narrowed slightly to open-pit electrification during Dr Bappa Banerjee’s talk, ‘An electric future for mine haulage’. Dr Banerjee, General Manager of Mining Equipment for Wabtec, emphasised from the off that there was no one-size fits all solution to going electric in this sector.

“It’s becoming clear to us…that perhaps it will be a combination of technologies that really help us get to a solution that is feasible,” he said.

This solution, he said, depended on the mine application and haulage scenario, underlining the need for technology flexibility.

In his presentation, Dr Banerjee pitted a diesel-powered haul truck with 2,500 horsepower (1,864 kW) as his baseline solution against a hybrid solution with a 2,500 hp diesel engine and 200 kWh battery as one alternative, and all-electric truck platforms equipped with trolley assist (with 800 kWh battery) and stationary charging (1,200 kWh battery).

The energy cost versus productivity outcome he showed proved his earlier point about different applications suiting different solutions, with varied results depending on if these trucks were deployed on downhill, uphill or flat hauls.

GE Transportation, since merged with Wabtec, has previously demonstrated a battery-diesel hybrid solution on a Komatsu 830E-1AC and Wabtec has plans to release trolley solutions for Komatsu 830E-5 and 930E-5 haul trucks in 2021, so this analysis includes hard industry data.

Dr Banerjee concluded on the decision-making aspect of going electric: “These are not just point in time decisions we have to make regarding the CAPEX and where we are in the lifecycle of the mine, but decisions across decades sometimes.

“Perhaps the best way to approach this would be to start with a technology that is more flexible up front or has more options.”

Brian Huff, Vice President of Technology for Artisan Vehicle Systems, a Sandvik Mining and Rock Technology business unit, used his presentation to reinforce that battery-powered solutions were the way forward in the underground environment.

‘Rethink the machine, not the mine’ was the title of his presentation and Huff stayed true to it from the off: “The basic message is that this is not as hard as you think it is. There is a real big change coming to the mining industry, but it may not be as difficult as you think to accomplish a conversion to battery-electric equipment.”

Similar to Hedqvist’s mention of the newfound freedom available to engineers when designing these next generation battery-electric machines, Huff explained that Artisan’s generation three BEV blueprint started with a battery-electric driveline and built from there.

“Major parts of the frame can be removed to facilitate swapping…[and you can have] double to triple the power density of the machine (compared with the diesel-powered equivalent) to improve performance,” he said.

He moved on to tackle the usual range anxiety question head on, displaying a video of a 13 km haul on a one-in-seven grade. Within this, he showed that the ability to swap batteries during the uphill haul meant there was no loss in haulage productivity when compared with the a similar payload diesel-powered machine.

The time losses related to battery swapping – around six minutes per swap with the Z50 – were more than offset by the increased haulage speed, according to Huff. “It is about 10% faster on the climb,” he said when comparing the BEV unit with a conventional diesel truck.

Productivity could be further boosted with the introduction of Artisan’s patented AutoConnect system. Fitted on the company and Sandvik’s newest 18 t payload LH518B LHD, this system allows the battery swap to be completed in well under five minutes, according to Huff. IM understands an AutoConnect retrofit option could allow the Z50 haul truck to match that swap time.

Add to this productivity benefit, decreases in operating cost and total cost of ownership, and it is hardly surprising Barrick recently signed off on a trial of four of these Z50s at its Turquoise Ridge joint venture gold mine in Nevada.

Safety, cost, maintenance, productivity and even battery life; you name it, The Electric Mine Virtual Conference discussed it.

The good news is a second dose of electrification talk is only four months away, with The Electric Mine 2021 conference taking place on March 15-16, 2021, in Stockholm, Sweden.

Sandvik and Barrick confirm Artisan Z50 trials at Turquoise Ridge gold mine

Sandvik and Barrick have confirmed the signing of a partnership agreement for trialing and enhancing battery-electric vehicles (BEVs) for underground hard-rock mining.

During a three-year production trial, Sandvik will deploy four Artisan Z50 BEV trucks at the Turquoise Ridge gold mine, part of the Nevada Gold Mines joint venture (JV), Sandvik said. Barrick is the operator of the JV, which is the single-largest gold-producing complex in the world, forecast to produce a total of 3.4-3.65 Moz of gold during 2020.

The announcement follows an acknowledgement of such a deal by President of Sandvik Mining and Rock Technology, Henrik Ager, earlier this month.

The Z50 haul truck, with a 50 t payload capacity, is a ground-up design that seamlessly integrates the most capable and proven battery electric powertrain available in the mining industry with the latest and most coveted features of any haul truck on the market today, according to Sandvik.

It is equipped with AutoSwap, a patented self-swapping system for the Artisan battery pack. This makes battery swapping faster and easier with a minimum amount of manual handling: changing the battery only takes about six minutes, and it can be done in a passing bay or old re-muck bay with no overhead cranes or external infrastructure needed.

In phase 1 trials, the Z50 truck already achieved more than 1,400 hours of production with over 1,400 loads, according to Sandvik. It reached production operation of up to 18 hours per day, with speeds of over 10 km/h observed on the ramp to the tip.

Some of the key performance indicators in the new partnership will include the performance of the BEV technology in a production environment, mechanical availability, average lifecycle cost and overall production cost, Sandvik said.

“We are always looking at ways to improve our performance, both in terms of sustainability and operational efficiency,”  Mark Bristow, Barrick’s President and CEO, said. “This partnership with Sandvik is exciting and will give us first-hand experience in BEV technology in our own production environment. It is a significant step to furthering our BEV strategy across the group.”

Ager added: “I am very pleased that Barrick and Sandvik have teamed up to perform these extensive trials in a daily production environment. It gives us the possibility to prove the performance of our BEV technology.

“The purely battery-powered truck helps to reduce heat and emissions underground, helping mines reach their sustainability targets and reduce ventilation costs. This raises the bar for what is possible and enables an all-new level of production and cost reduction for underground hard rock mines.”

A dedicated site project team will be jointly working with the Barrick operations team during the trial period to ensure that all data is captured and the experience from both Sandvik and Barrick is used to ensure the uptime and productivity targets are met, Sandvik said.

Barrick to receive three more Artisan Z50 battery-electric trucks, Ager says

Sandvik Mining and Rock Technology has signed an agreement with Barrick Gold that could see four Artisan Z50 battery-electric trucks deployed at the miner’s majority-owned operations in Nevada, Henrik Ager confirmed this week.

Speaking at Sandvik’s Capital Markets Day on Tuesday, Ager, President of Sandvik Mining and Rock Technology (soon to be President of Sandvik Mining and Rock Solutions), said the company had just signed “a cooperation partnership” with Barrick in relation to the delivery.

“We have one (truck) operating already and have three coming,” he said.

Back in May, a Barrick spokesperson confirmed to IM that an ongoing trial involving a 50-t payload Z50 was expected to be finalised in the June quarter of this year, “with the option to extend, should the KPIs not be met”. The machine was being tested at Turquoise Ridge, a gold mine operated under the Nevada Gold Mines company, owned 61.5% by Barrick and 38.5% by Newmont.

Based on this order, IM assumes the Turquoise Ridge trial was a success.

Alongside this reveal, Ager, talking up the company’s next-generation AutoMine® Concept vehicle recently revealed at the Innovation in Mining event, said the company currently had automation solutions at 59 sites across the mining industry. This compared favourably with solutions at 43 sites 18 months ago, and 19 sites back in 2016.

Sandvik to form new crushing and screening business area

Sandvik has decided to spin off its Crushing and Screening division into a new business area called Sandvik Rock Processing Solutions (SRP).

The reason for this structural change, which will happen as of January 1, 2021, is to further accelerate profitable growth within rock processing, based on Crushing and Screening addressing separate parts of the value chain and facing different competition to the other Sandvik Mining and Rock Technology divisions, the company said.

“Sandvik is market leading within rock processing and our Crushing and Screening division is a well-performing business with exciting growth opportunities,” Stefan Widing, President and CEO of Sandvik, said. “The business is today already operating quite independently from the rest of Sandvik Mining and Rock Technology, with its own manufacturing, sourcing and aftermarket. By establishing Rock Processing Solutions as a business area we will improve transparency and strengthen our growth ambitions within the area.”

In line with this move, Sandvik has appointed Anders Svensson, President of the Crushing and Screening division since 2016, to President of the business area Sandvik Rock Processing Solutions and a new member of the Sandvik Group Executive Management, as of 1 January 2021. Svensson joined Sandvik in 2008 and has, prior to his current position, had several different management positions within Sandvik and in Metso Minerals.

The crushing and screening business had, as a division within Sandvik Mining and Rock Technology, about SEK7.4 billion ($837 million) in sales and a 15.9% operating profit margin in 2019 with about 2,000 employees.

The Sandvik Mining and Rock Technology business area will continue to be led by Henrik Ager and will, as of 1 January 2021, change name to Sandvik Mining and Rock Solutions (SMR), the company added.
