BluVein charges into mine electrification space

BluVein, armed with its “dynamic charging” philosophy, is pitching a different option to miners looking to electrify their underground operations over the long term.

While battery-electric machines such as light utility vehicles, mobile mining support equipment, and low-to-medium tonnage LHDs and trucks have spread throughout major mining hubs like North America, Europe and Australia, the next step is electrifying the machines with the heaviest duties in the underground mining space.

If the sector settles for battery-electric options in this weight class for uphill haulage scenarios, they will need to leverage bigger batteries, more battery swapping or some additional charging infrastructure to power vehicles up ramp.

Two of the leading mining OEMs in the electrification space are considering all the above.

Sandvik, through its wholly owned Artisan Vehicles subsidiary, is developing a 65 t payload battery-electric haul truck with a bigger battery than its 50-t vehicle (the Z50) that will see quick battery swapping employed on uphill hauls, while Epiroc is weighing the potential of fully-electric operation with a battery and trolley combination in its larger payload class trucks.

BluVein is intent on laying the groundwork for multiple OEMs and mining companies to play in this space without the need to employ battery swapping or acquire larger, heavier batteries customised to cope with the current requirements placed on the heaviest diesel-powered machinery operating in the underground mining sector.

It is doing this through adapting charging technology originally developed by Sweden-based EVIAS for electrified public highways. The application of this technology in mining could see operations employ smaller, lighter battery-electric vehicles that are connected to the mine site grid via its Rail™ and Hammer™ technology and a sophisticated power distribution unit to effectively power electric motors and charge a vehicle’s on-board batteries.

This flexible technology is set for a trial later this year, with the company – a joint venture between EVIAS and Australia-based Olitek – already busy behind the scenes enlisting a number of funding partners to push forward with a collaborative pilot aimed at demonstrating the next generation of trolley assist technology.

With this aim in mind and knowledge of previous trolley projects at underground mines, IM put some questions to BluVein Founder, James Oliver.

IM: What input does Olitek provide within BluVein? Do they produce customised prototype battery-electric machines?

JO: BluVein is a new company formed through a partnership between EVIAS and Olitek. While we are a new venture, unlike traditional start-ups, BluVein is backed by two highly experienced long-standing companies and is seeking to enable the fully-electric mine of today.

The biggest need for electric mining vehicles is in heavy-duty load and haul applications on inclined roads. In this instance, batteries on their own are not up to the task – not even close. Dynamic charging is the game-changing technology that will enable fully-electric heavy-duty load and haul on inclined roads.

In the partnership, Olitek provides the mobile vehicle, robotics, electrical and mining environment expertise to enable BluVein to operate safely and reliably in a mining environment. BluVein is currently working with a number of mining vehicle OEMs to integrate the BluVein system to suit their on-board battery and motor architecture, enabling safe dynamic charging from a standardised slotted rail system.

The joint venture does not produce customised prototype battery-electric vehicles or battery machines, and we are vehicle OEM-agnostic; we are open to working with any battery-electric vehicle manufacturer enabling standardised dynamic charging.

IM: What companies are involved in the collaboration mentioned? What is the aim of this collaboration (timelines, goals, etc)?

JO: Currently we are not able to disclose which mining companies and vehicle OEMs we are working with – it will be revealed in the not-too-distant future. They are, however, a selection of very well-known major companies from Sweden, Canada and Australia. We are open to other like-minded, early adopters to join the BluVein collaboration.

Our aim is to commence building our industry-backed technology demonstration pilot site in Brisbane, Australia, by late 2021 in a simulated underground environment. This will involve a section of BluVein rail and at least one electric vehicle fitted with the BluVein hammer system to demonstrate dynamic charging whilst hauling loaded up an incline.

IM: What are your overhead systems (BluVein Rail) providing that your typical underground trolley systems are not providing? How does the infrastructure required compare with, say, what Vale has in place at Creighton and Coleman in Sudbury for its Kiruna trucks?

JO: Existing trolley assist systems that utilise exposed high voltage conductors cannot be used in many mining jurisdictions globally due to safety concerns and an inability to comply with mining regulations. This is particularly the case in underground mines where clearance above mobile fleets is limited. The BluVein rail system is unique as all high voltage conductors are safely housed within ingress protection (IP) rated slots. This effectively mitigates against risks of accidental contact by mining personnel or the vehicles.

The safe and standardised systems allow for the charging of a vehicle’s batteries whilst simultaneously powering the electric-drive motors. This gives a battery-electric vehicle almost unlimited range and eliminates the requirement for battery swapping, downtime and charge bay infrastructure requirements.

And BluVein Rail does not need to be installed in all parts of the mine – only in the heavy-duty cycle zones such as mine declines and pit ramps. When tramming/hauling on flat gradients, mining vehicles operate on their own internal batteries. This dramatically reduces the system installation complexity and installation cost. Where the BluVein Rail terminates, the vehicle automatically disconnects and reverts to its on-board batteries for power, without stopping.

Ease of maintenance is one of our focus points for BluVein. The BluVein system is developed to handle typical mining drive terrain conditions so no special maintenance is required to cater for conductor contact relative to the vehicle. Our BluVein Hammer, an all-terrain trolley, takes care of this. This provides the connection between the mobile machinery and the BluVein slotted rail. As the vehicle moves through an inclined underground tunnel or along a pit ramp, the Hammer maintains the electrical connection even over rough road conditions. Operator assist controls, such as smart auto connect and disconnect functionality, are also incorporated.

BluVein is the ‘next generation’ of trolley assist technology with all the benefits and none of the negatives of the old systems.

IM: How long and steep an uphill climb is required, on average, to make the business case work in the favour of BluVein technology over your typical battery-only system? When does the TCO equation tip in favour of your solutions over other trolley systems on the market?

JO: Typical battery systems are super high cost when you consider the full impact of charge bay infrastructure, numerous large operating batteries per vehicle and rapid battery life decay. BluVein, however, has a relatively low capital cost in comparison as it enables smaller, lighter and lower power on-board batteries to be used that never require swapping or static charging.

Therefore, from day one, the TCO for BluVein will likely be favourable compared to typical battery-only systems, regardless of haul length.

IM: Are BluVein Hammer or BluVein Rail already installed at mine sites around the world? What models of machines have they been integrated on?

JO: The underlying technology for the BluVein Rail and Hammer has been developed over the past 11 years with EVIAS for electrified highways. BluVein is the adaptation of this technology specific to the harsh conditions found within mining.

The BluVein system has been designed to suit nearly all current mining battery-electric vehicles so that a single BluVein Rail installed in a mine can power the entire fleet, even if that fleet is comprised of mixed OEM machinery.

A working EVIAS system has been installed in an open highway setting in Sweden, but no mining applications exist at this point. As mentioned, BluVein will have a pilot site underway by the end of 2021.

IM: Given a Volvo TA15 all-electric hauler is pictured on your website, are you also working with open-pit miners on this collaboration?

JO: BluVein is not just suited to underground applications, however, initially that is the focus given the urgency around eradicating diesel emissions and particulate matter and its carcinogenic properties.

BluVein pilot site concept – simulated underground

BluVein has strong application in open-pit mining and in quarry environments to reduce greenhouse gas emissions and improve productivity and costs. The technology can leverage all the same advantages seen underground in open-pit applications. The bonus with underground is we have free infrastructure to hang the rail from.

A number of our partner mining companies are assessing the BluVein system for both surface and underground deployments.

Epiroc to acquire Meglab as part of battery-electric mining equipment push

Epiroc has agreed to acquire Meglab, a Canada-based company with expertise in providing electrification infrastructure solutions to mines, as it looks to further support mining customers in their transition to battery-electric vehicles.

Meglab, based in Val-D’Or, Quebec, Canada, is a technology integrator that designs, manufactures, installs and supports practical and cost-effective electrification and telecommunications infrastructure solutions to customers in several countries. Its products and solutions include system design, substations, switchgears and automation system solutions, enabling the infrastructure needed for mine electrification and equipment charging solutions, as well as for digitalisation and automation of operations, Epiroc says. It has more than 240 employees and had revenues in 2020 of about C$49 million ($39 million).

Helena Hedblom, Epiroc’s President and CEO, said: “Epiroc is proud to be the leader in providing battery-electric vehicles for the mining industry, improving customers’ work environment and lowering their emissions while increasing their productivity. The acquisition of Meglab will strengthen our capacity to provide the infrastructure required as mines transition to battery-electric vehicles.”

The acquisition is expected to be completed in the June quarter, with the purchase price not material relative to Epiroc’s market capitalisation, the mining OEM said. The business will become part of Epiroc’s Parts & Services division and will continue to be based in Canada.

In a separate release, Meglab said the two comapanies collective goal is to develop the mine of the future, with the organisations pooling its respective assets and expertise in pursuit of this target.

“Together, we will position ourselves as the leaders of all-electric and intelligent mines,” it said. “This synergy will provide various growth opportunities worldwide, both for Meglab and for the team members that will collaborate with their co-workers in this new expanded team.”

Mine Master testing new battery-electric bolter at KGHM Lubin

Mine Master has hopped on-board the mine electrification train, announcing the release of its first electric bolter for underground mining.

The Roof Master 1.8KE has started working at KGHM’s Lubin polymetallic mine in Poland, the equipment maker said.

Designed to work in galleries from 3 m to 5.8 m in height, the bolter is equipped with a 1.8 m mechanised bolting mast for nine bolts.

The 120 kWh sodium-nickel battery installed on board can be recharged by using the existing mine power network in the 500-1,000 V range, Mine Master said. For this purpose, a battery charger is built onto the machine chassis, with energy recuperation also possible during downhill tramming.

In addition, the bolter is equipped with a closed air-conditioned operator’s cabin, Mine Master said.

“The battery-electric solution will help the mine to reduce gas emissions, improve safety and ease maintenance,” Mine Master explained.

Fortescue to test battery-electric, fuel cell tech in prototype 240 t haul truck

Fortescue Metals Group has confirmed it is in the process of developing an in-house, non-diesel 240 t haul truck prototype that will test both battery-electric and fuel-cell electric drivetrain technology in the Pilbara of Western Australia.

Speaking at its Investor and Media Day on Wednesday, Fortescue Chief Operating Officer, Greg Lilleyman, said the two-phase project would “offer a step-change opportunity to reduce our emissions”.

He explained: “With around a quarter of Fortescue’s Scope 1 and 2 emissions attributable to our mobile haul fleet, this is a significant opportunity to drive our pathway to net-zero operational emissions.”

The drivetrain of the 240 t prototype truck will be powered by the company’s integrated renewable energy network, he added.

Phase one of the project will see a battery-electric powertrain on-board the prototype truck tested and trialled, from an operational perspective, in the Pilbara. Phase two of the project will consider hydrogen fuel cell powertrains, Lilleyman added. The drivetrains will have the capacity to regenerate power on downhill haulage.

While no specific timeline was provided for the project, the company did say the program schedule was targeted to align with the replacement cycle of the company’s existing haul trucks.

Kirkland Lake Gold to trial battery-powered Sandvik LH518B at Fosterville

Kirkland Lake Gold, one of the leaders in battery-electric vehicle adoption in mining, is to trial a Sandvik LH518B LHD next year at its Fosterville underground mine, in Victoria, Australia, Rob McLean, the operation’s Chief Mining Engineer, has confirmed.

Speaking during a session titled: ‘What are Fosterville’s Current and Future Technology and Innovation Requirements, and Why?’ at the IMARC Online event, McLean said the trial is part of the company’s vision to “have a fully electric mine”, with the immediate goals being to remove diesel emissions and reduce heat at the operation.

Longer-term, electrifying the company’s fleet could result in the need for less ventilation, lower power costs and the elimination of infrastructure upgrades at the high-grade gold operation, he said.

Sandvik launched the 18 t battery-electric LH518B during its Innovation in Mining event in late September.

The loader, a Sandvik and Artisan Vehicle Systems joint development effort, has been designed from the ground up, entirely around the loader’s Artisan™ battery system and electric driveline to best leverage the possibilities the battery technology brings, Sandvik says. It can fit in a 4.5 x 4.5 m tunnel and is equipped with three 2,000 Nm permanent magnet motors and 450 kN of tractive effort. It can operate at speeds of up to 30 km/h and has 560 kW of continuous power output (peak power output of 660 kW).

McLean said the trial of the LH518B would inform the mine’s future electrification direction, but he said the company was also considering the use of battery-electric or trolley assist trucks at the operation, in addition to battery-electric charging/spraying rigs.

Kirkland Lake says its Macassa mine, in Ontario, Canada, is a “world leader in the use of battery-powered equipment” with more than 80% of its fleet made up of battery-powered vehicles from the likes of Artisan, Epiroc and RDH Scharf.

Epiroc battery-electric retrofit solution coming in Q1 2021

Epiroc has confirmed that its battery-electric retrofit solution for diesel-powered machines is expected to launch in the March quarter of 2021.

Speaking at the company’s Capital Markets Day Fika 2020 event on Monday, Mattias Olsson, SVP Corporate Communications, confirmed the launch date during an investor Q&A session.

Sami Niiranen, President of Epiroc’s Underground division, said during the same event that the ST1030 underground loader would be the first unit to undergo a diesel- to battery-powered conversion. These 10-t-payload LHDs are the company’s largest loader segment, according to Niiranen.

Jess Kindler, President of Parts and Service, said these conversions were expected to be conducted during a midlife service rebuild process.

Epiroc ‘new generation’ Boomer drill rig to launch in 2021

Epiroc is planning a “new generation” Boomer face drilling launch in 2021 as it looks to capture more market share in the underground mining contractor market.

Speaking at Epiroc’s Capital Markets Day Fika 2020 event on Monday, Sami Niiranen, President of Epiroc’s Underground division, said the new rigs would be designed for increasing both production and safety.

The company referred to the machine in presentation slides as a “true development rig, fully equipped for multi-task operation and automation”, with Niiranen adding that the Boomer will come with a battery-electric driveline option.

During his presentation, Niiranen also provided investors and interested parties with the latest numbers on Epiroc’s digitalisation and automation solutions.

He confirmed that more than 1,000 machines were now connected to the company’s Certiq telematics system, while there were circa-90 production Simba production drills operating autonomously. This came alongside around 50 automated underground LHDs and some 670 drills with full automation capability.

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.

Aeris Resources adds battery-electric 20 t carrier/loader to Tritton fleet

Aeris Resources has confirmed the arrival of the battery-electric retrofit ‘TRITEV’ 20 t underground loader at its Tritton copper operations, with the company having added the Integrated Tool-Carrier/Loader to its fleet at the New South Wales, Australia, mine.

3ME Technology and Batt Mobile Equipment (BME) unveiled this industry-first machine last month, with 3ME saying the machine would head to Tritton later this year as part of an initiative developed under Project EVmine, with the help of METS Ignited.

The collaboration between 3ME and Aeris Resources started all the way back in 2017, Aeris Resources said in its arrival announcement on LinkedIn

Based on a second-hand Volvo diesel-powered L120E, the TRITEV required a “ground-up rebuild” from the 3ME and BME teams, 3ME Chief Business Development Officer, Steven Lawn, told IM last month.

This included removing all diesel internal combustion engine components, except the transmission and drivetrain; modelling the expected duty cycle at Tritton; developing a battery-electric system to suit the application at hand; writing the vehicle control unit software; integrating the system into the existing platform; and providing a mechanical overhaul of the machine.

The 3ME and BME teams planned to test the machine at the Newstan mine, in New South Wales (previously owned by Centennial Coal and now on care and maintenance), ahead of sending to Tritton.
