Vale and Wabtec have announced a master service agreement (MSA) to further increase the efficiency and operations of the Evolution Series (EVO) Locomotive fleet on the Estrada de Ferro Carajás (EFC), in Brazil.

The strategic 10-year deal, valued at R$1.8 billion ($341 million), will optimise the maintenance services for Vale’s fleet increasing availability, reliability and the potential for expanded freight transport on the EFC connecting the southeast of Pará to the capital of Maranhão, São Luís, Vale says. The EFC is around 1,000-km-long, covering 28 municipalities. The railway branch is around 100-km-long and connects EFC to the S11D project, in Canaã dos Carajás.

Carlos Medeiros, Vice President of Operations at Vale, said: “This long-term strategic agreement means a new standard of reliability, availability and safety for EFC locomotives, reinforcing our commitment to consistently invest in the quality and technology of our railway operations and promote the technological development of the railway sector in Brazil.”

Wabtec will analyse locomotive performance data from the last three years at EFC. The company also will provide real-time monitoring on 5,000 parameters of the EVO locomotives operating on the railway. Wabtec’s Global Performance Optimisation Centers will evaluate the data and identify opportunities for continuous performance improvement and optimization of maintenance cycles, reducing towing and failure rates.

Danilo Miyasato, President and Regional Leader of Wabtec in Latin America, said: “Wabtec has a proven history of providing integrated services designed to maximise reliability and availability of customers’ locomotives at optimal operating costs. This contract reinforces our long-standing working relationship with Vale to drive sustainable and efficient growth of EFC’s railway operations.”

In addition to planning and supplying parts for preventive maintenance, the agreement foresees the creation of specialised jobs in São Luís, contributing to the local economy and strengthening regional infrastructure, Vale says.

Vale and Wabtec have worked together for almost three decades to supply locomotives, materials and components for the EFC. In July 2023, the two companies also announced an agreement for the purchase of three FLXdrive battery locomotives, which will operate for the EFC, which represents an important step in its journey towards decarbonisation.

Vale hits renewable power milestone ahead of 2025 deadline

Environmental, Mining services, Power supply for mines, Sustainable mining, , , ,

Vale has announced that all the electricity used in its operations in Brazil in 2023 came from renewable sources, such as hydroelectric, wind and solar power plants. Thus, the company has achieved its goal of having 100% renewable electricity consumption in Brazil two years ahead of its original 2025 schedule.

The information is highlighted in the 2023 edition of the Vale Integrated Report.

Having reached the target, Vale has zeroed its indirect CO2 emissions in Brazil, which correspond to Scope 2 emissions. The company still has the challenge of achieving 100% renewable energy consumption in its global operations by 2030. At the moment, this indicator stands at 88.5%.

Vale Director of Energy and Decarbonization, Ludmila Nascimento, said: “We are announcing an important milestone in Vale’s decarbonisation strategy, which aims to reduce its Scope 1 and 2 CO2 emissions (direct and indirect) by 33% by 2030 and to become net-zero by 2050. As we are progressing on our targets, we are helping to make Brazil’s energy matrix even cleaner, contributing to society’s fight against climate change.”

The start-up of the Sol do Cerrado solar complex in November 2022 was key to achieving the target two years ahead of schedule. Located in Minas Gerais, Brazil, the solar complex represented an investment of $590 million by Vale. It is one of the largest solar energy parks in Latin America, with an installed capacity of 766 MW (peak), equivalent to the consumption of a city of 800,000 inhabitants. In July 2023, the complex reached its maximum capacity. It has the potential of contributing to around 16% of all the electricity consumed by Vale in Brazil.

The path towards 100% renewable consumption began to be traced by Vale back in the 1990s, when the company acquired its first hydroelectric plants. Today, Vale is supplied by a renewable energy portfolio of 2.6 GW of installed capacity, equivalent to the consumption of more than 3 million inhabitants. There are 14 assets held through direct and indirect participation in consortia and companies (ten hydroelectric plants, three wind farms and Sol do Cerrado). If it were a power generator, Vale would be the 15th largest in the country.

In its global operations, Vale is also moving towards 100% renewable energy consumption by 2030. The company invests in joint venture partnerships, renewable generation certificates in contracts and innovation initiatives for better efficiency in the use of batteries.

Vale is also working to reduce its direct Scope 1 emissions. In the mines and railroads, where diesel is currently intensively consumed, the company is studying the adoption of alternative fuels, such as ethanol for trucks and green ammonia for locomotives. In the pelletising furnaces, the strategy is to replace anthracite with zero-emission biocarbon, made from the carbonisation of biomass.

Last year, Vale signed an agreement with Wabtec for the supply of three electric locomotives and the start of studies into the development of a green ammonia-powered locomotive engine. The company also produced pellets with 100% biocarbon for the first time in an industrial test.

Wabtec and its launch customer, Roy Hill, have celebrated the debut of the FLXdrive battery locomotive, the world’s first 100% battery-powered, heavy-haul locomotive for mainline service.

The ceremony unveiled the unique, striking pink-coloured locomotive at Wabtec’s design and development centre in Pennsylvania in front of employees, customer executives, and government and community officials.

“This FLXdrive locomotive represents a major step in the journey to a low-to-zero-emission future in the rail industry,” Rafael Santana, President & CEO of Wabtec, said. “The FLXdrive is driven from within by our battery technology and the innovative spirit of our employees. Roy Hill is an ideal customer to partner with given their leadership and excellent operational record.”

Roy Hill’s FLXdrive battery-electric locomotive will feature an energy capacity of 7 MWh. Based on the route and company’s rail operations, the FLXdrive is anticipated to provide a double-digit percentage reduction in fuel costs and emissions per train. Once Wabtec completes the final battery installations and track testing, the locomotive will begin its 17,000 km journey in 2024 for delivery to its new home in the Pilbara region of Western Australia, one of the world’s premier mining precincts.

Gerhard Veldsman, Chief Executive Officer, Hancock Prospecting Group Operations, owner of Roy Hill, said: “The foresight of our Executive Chairman, Mrs Gina Rinehart AO, has been instrumental in establishing an environment in which we can successfully leverage the ingenuity of our people alongside key partners like Wabtec to transform our rail and mining operations through nextgeneration technologies.

“The FLXdrive locomotive represents not only a first for the Pilbara, but a first for the mining industry. The technological smarts that have gone into the development of the loco makes it well suited for our rail network. By using regenerative braking, it will charge its battery on the 344 km downhill run from our mine to port facility and use that stored energy to return to the mine, starting the cycle all over again. This will not only enable us to realise energy efficiencies but also lower operating costs.”

Today, Roy Hill uses four Wabtec ES44ACi “Evolution Series” diesel-electric locomotives in a consist to pull trains that are typically 2.7 km in length carrying more than 33,000 t of iron ore. The addition of the FLXdrive will form a hybrid locomotive consist with Wabtec diesel-electric locomotives, and recharge during the trip through regenerative braking. The FLXdrive manages the overall train energy flow and distribution through its state-of-the-art energy management software. It is also designed with a unique battery thermal management system using liquid cooling to withstand the Pilbara heat, where ambient temperatures can exceed 55°C (131°F).

Roy Hill’s iconic pink livery symbolises the company’s commitment to assisting research and those suffering from breast cancer. To commemorate the FLXdrive’s premiere, Roy Hill, and Breast Cancer Awareness Month, Wabtec donated $50,000 to Linked By Pink, a non-profit organisation consisting of Erie area survivors diagnosed with breast cancer before the age of 45.

IoT, Mining equipment, Mining safety, Mining services, , , , , , , ,

Wabtec’s Digital Mine division says it has received a series of orders for 3,500 of its new Generation 3 Collision Avoidance System (Gen 3 CAS) from three major global mining companies.

The capabilities of the new system will drive performance and safety improvements at the customers’ mining operations, the company says.

When Wabtec launched this system in June, it said its innovation focus was on shifting from traditional proximity detection to true collision avoidance.

Nalin Jain, President, Digital Intelligence for Wabtec, explained: “These orders demonstrate the Gen 3 CAS’s value and rapid market adoption since we launched the system in June. The Gen 3 CAS is the only solution aligned with the industry’s best practices that also meet the functionality requirements of our customers.”

Installing Gen 3 CAS across a customer’s mining operations will improve safety, bolstering their zero-harm objectives, according to the company. By minimising the risk of vehicle interactions, the Gen 3 CAS will contribute to reduced downtime, increased productivity and optimised resource utilisation.

Wabtec says its customers can confidently rely on this innovative solution to drive performance and achieve their operational objectives.

Wabtec Digital Mine’s Gen 3 CAS offers a range of class-leading advanced capabilities not seen on any other solution, according to the company. These include predictive beam curving, context-based definitive voice-based alerts, real-time self-test, superior accuracy via Ultra High Precision Global Navigation Satellite Systems and the most advanced rules and intelligence engine in the industry. The system’s brand-new user interface, validated by Professor Robin Burgess-Limerick, a human factors expert, has been designed so that vehicle operators receive appropriate feedback from the Gen 3 CAS, Wabtec says. It replaces “beeps-and-buzzer” technology with sophisticated, discreet, directional and audible warnings, enabling operators to work without distraction and respond instantaneously to audible alerts.

Jain added: “We are improving safety and operational efficiency, so we have entered into agreements with several global mining companies who recognise the potential of Wabtec Digital Mine’s Gen 3 CAS to transform their mining operations. These customers are installing the Gen 3 CAS to enhance their mining fleet’s safety standards and performance.”

Henro van Wyk, Vice President and General Manager of Wabtec Digital Mine, said: “We are thrilled that multiple global mining companies have selected Gen 3 CAS for their operations. These deals represent a significant achievement for Wabtec’s Digital Mine team positioning the business as the global leader in mining technology by redefining the meaning of true collision avoidance. Mining operations using the Gen 3 CAS will achieve new levels of safety, efficiency and productivity across their mining operations.”

Vale and Wabtec look to decarbonise Carajás Railroad operations with battery power and ammonia

Environmental, Mine operation news, Mining equipment, Power supply for mines, Steel and iron ore, Sustainable mining, , , , , , , ,

Vale has announced a partnership with Wabtec Corporation to advance the decarbonisation of the company’s rail operations. The deal includes an order for three of Wabtec’s FLXdrive battery locomotives and a collaboration to test ammonia as a potential clean, alternative fuel to replace diesel.

The three 100% battery-powered FLXdrive locomotives will be used on the Carajás Railroad (EFC), which runs the world’s largest iron ore train consisting of 330 railcars transporting 45,000 t.

Today, three to four diesel locomotives pull the train. Once delivered, the FLXdrives will join the diesel locomotives to form Brazil’s first hybrid consist pulling the train uphill for 140 km in Açailândia, in the state of Maranhão, where fuel consumption is the highest. The FLXdrives will replace the two diesel locomotives, known as “dynamic helpers”, that are used to pull the train uphill today, Vale says.

Wabtec will build the FLXdrive locomotives at its plant in Contagem (state of Minas Gerais). The locomotives’ delivery is forecast for 2026.

Vale’s Director of Energy, Ludmila Nascimento, said: “Initially, we are maximising energy efficiency, replacing the diesel locomotives in the dynamic helper with battery ones, but the idea is that, in the future, the other locomotives on the train can be fueled by ammonia. This way, we would have a clean operation at EFC. This agreement is the first of many that we are seeking in order to accelerate the decarbonization of our railway operation.”

Vale and Wabtec will work together on a study to use ammonia as a clean alternative fuel, which does not emit CO2. The study will initially be carried out as lab tests to validate performance, emission reductions and feasibility. Among the advantages of ammonia is the fact that it allows the locomotive a longer range than other carbon-free fuels. In addition, ammonia has a high-octane rating and an established large-scale distribution infrastructure, according to Vale. The two companies will carry out the study in a laboratory over the next two years.

The FLXdrive locomotive’s energy management system recharges the batteries along the route as the train brakes.

Alexandre Silva, Manager of Vale’s Powershift Program, said: “It’s what we call regenerative energy produced by dynamic braking. Today, that energy is lost when a traditional locomotive brakes. In the downhill sections, we will be able to recharge the batteries, without having to stop the train’s operation.”

Vale introduced the Powershift Program to study alternative technologies to replace fossil fuels with clean sources in the company’s operations.

The FLXdrive locomotives are estimated to save 25 million litres of diesel per year, considering the consumption of all the railway’s trains that use the dynamic helper. These savings would reduce carbon emissions by approximately 63,000 t, the equivalent emissions of around 14,000 passenger cars per year, it says.

Danilo Miyasato, President and General Manager of Wabtec for Latin America, said: “Technological advances in battery power and alternative fuels are accelerating the decarbonisation journey for railroads. Vale’s innovative approach to adopting alternative fuels for its locomotives will benefit its customers, shareholders and communities. The FLXdrive provides Vale productivity, safety, fuel economy and emission reductions for its rail network.”

In 2020, Vale announced an investment of between $4 billion and $6 billion to reduce its direct and indirect emissions (Scope 1 and 2) by 33% by 2030. Today, Vale’s rail network represents 10% of the company’s carbon emissions. The initiative is one more step towards achieving the goal of net zero carbon emissions by 2050, in line with the ambition of the Paris Agreement to limit global warming to below 2°C by the end of the century.

The company also committed to reducing its net emissions from its value chain (Scope 3) by 15% by 2035.

Wabtec to provide Fortescue locomotives with another 20 years of life

Equipment maintenance, Mining equipment, Mining services, Steel and iron ore, , , , , , ,

Wabtec Corporation has announced an agreement to modernise locomotives for Fortescue Metals Group, representing Wabtec’s delivery of the first fleet of modernised locomotives for an Australia-based customer.

The fleet will be transformed into AC44C6M locomotives to meet the performance requirements of Fortescue while delivering operational and environmental efficiencies, it explained.

“While we have completed more than 1,000 modernisations for customers globally, it’s a first for Australia and demonstrates Fortescue’s commitment to drive more sustainable rail operations,” Wendy McMillan, Senior Regional Vice President, South East Asia, Australia and New Zealand, said.

“By repurposing and rebuilding our locomotives, we give these heavy-haul trains another 20 years of life, while reducing the fuel consumption and maintenance, and repair and overhaul expenses by up to 20%. For Fortescue, the modernised trains will deliver up to a 55% increase in tractive effort and more than 40% increase in reliability.”

The modernised locomotives will benefit from improved performance and increased reliability with new features including a UX engine, new electrical cabinets, a new design high-efficiency radiator and radiator cab, an upgraded control system to remove obsolescence, and AC traction with individual axle control, Wabtec explained.

General Manager Hedland Operations, Mark Komene, said: “The procurement of the modernised locomotives is an important element of Fortescue’s locomotive fleet strategy. This newly modernised fleet will enable substantial long-term capital and operating costs savings, provide the latest traction and control technology, and enable future upgrades to alternative energy sources such as battery electric in support of Fortescue’s industry-leading target to be carbon neutral by 2030.”

The new AC44C6M locomotives will be rebuilt at Wabtec’s Fort Worth facility in Texas, USA, before making the journey to Western Australia over the next two years for deployment at Fortescue’s mining operations.

Wabtec’s modernisation program is a key component of the company’s effort to advance a circular economy. It updates ageing locomotives with customised solutions that range from simple changes including control system upgrades to complex restorations, such as the comprehensive transformation of an aged DC locomotive into an AC locomotive outfitted with state-of-the-art digital technology.

Fortescue, meanwhile, has progressively been looking to decarbonise its locomotive fleet, making plans to purchase two new battery-electric locomotives from Progress Rail, a Caterpillar Company, to transport its iron ore to port in Western Australia. This comes on top of trials at Fortescue Future Industries development facility in Western Australia of a locomotive operating solely on green ammonia and other green renewable fuels and technologies.

Roy Hill, in Western Australia, has announced the purchase of a Wabtec FLXdrive battery-electric locomotive, the world’s first 100% battery, heavy-haul locomotive for the region and the mining industry.

“We are committed to transforming the next generation of transportation by adopting advanced technologies that improve energy efficiency, lower operating costs and improve our rail and mining network,” Gerhard Veldsman, CEO of Roy Hill, says. “The FLXdrive locomotive will be the first for the region and the first for the mining industry and will improve our rail operations from the mine to Port Hedland.”

Roy Hill will receive the newest version of the FLXdrive battery-electric locomotive in 2023 with an energy capacity of 7 MWh. It is an upgrade from the 2.4 MWh prototype that was successfully tested in revenue service with a Class 1 railroad in the USA earlier this year.

Based on the route and Roy Hill’s rail operations, the FLXdrive is anticipated to reduce the company’s fuel costs and emissions in percentage by double digits per train. The ongoing use of the FLXdrive will also reduce ongoing operational costs through maintenance spend.

Simon Pascoe, General Manager of Engineering for Roy Hill, says: “Our analysis with Wabtec confirms the FLXdrive locomotive is ideally suited for our rail network. It has the horsepower to operate in a heavy haul train consist pulling loaded wagons with 35,000 t of iron ore, while at the same time reducing the entire train’s fuel consumption. The FLXdrive also is designed to function in the extreme heat of the Pilbara region.”

Today, Roy Hill uses four Wabtec ES44ACi “Evolution Series” diesel-electric locomotives in a consist to pull trains that are typically 2.7 km in length. The FLXdrive will replace one of the diesel locomotives to form a hybrid consist, and recharge during the trip through regenerative braking.

The FLXdrive manages the overall train energy flow and distribution through its Trip Optimizer system, an intelligent cruise control system programmed through artificial intelligence to respond to every curve and grade of the track in the most energy-efficient way possible, Wabtec says. It is also designed with a special liquid cooling system to withstand the Pilbara heat, where temperatures can reach 55°C.

Wendy McMillan, Regional Senior Vice President Australia and New Zealand for Wabtec, says: “This order demonstrates Roy Hill’s progressive and forward-thinking approach to the mining industry. By adopting this revolutionary technology in region, Roy Hill is pioneering new approaches to its operations that will benefit the company’s bottom line. The FLXdrive is a continuation of our growing partnership and shared vision to bring more efficient solutions to mining and rail industries.”

Wabtec’s goal is to develop the next generation of zero-emission locomotives. The company says it has a clear path to power new locomotives – and repower existing locomotives – with batteries, hydrogen internal combustion engines and hydrogen fuel cells. It is part of Wabtec’s vision for the rail industry to play a key role in building a clean energy economy and will enable the reduction of up to 300 Mt of global carbon emissions.

Rogerio Mendonca, President of Freight Equipment for Wabtec, says: “Controlling emissions is critical in the fight against climate change. The FLXdrive battery-electric locomotive is a bold step toward a low-to-zero-emission locomotive future. We continue working on solutions that cut the overall carbon footprint of the industries we serve through the development of low-emitting locomotives like the FLXdrive, and the use of alternative fuels such as bio-diesel, renewable diesel and hydrogen.”

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.

The Electric Mine charges on to Sweden

Following the success of the inaugural Electric Mine event in Toronto, Canada, in April, International Mining Events has wasted no time in confirming the 2020 follow up; this time in Stockholm, Sweden.

Taking place at the Radisson Blu Waterfront Hotel on March 19-20, 2020, The Electric Mine 2020 will be even bigger, featuring new case studies from miners implementing electrification projects and presentations from the key OEMs and service suppliers shaping these solutions.

A leading hub in Europe for mining equipment and innovation, Sweden was the obvious choice for the 2020 edition of the event. Miners including Boliden and LKAB have already made electric moves above and below ground, and the north of the country is set to host Europe’s first home-grown gigafactory, the Northvolt Ett lithium-ion battery cell facility.

Sweden and Finland also play host to Europe’s major mining OEMs such as Epiroc, Sandvik, Metso and Outotec (soon to possibly be Metso Outotec Corp), and the Nordic region has a rich mining innovation legacy.

Capacity crowd

The announcement of the 2020 Electric Mine edition comes hot on the heels of a hugely successful debut in Toronto.

With the Radisson Admiral, on Toronto Harbourfront, filled out to capacity, the circa-150 attendees were treated to more than 20 world-class papers from miners Vale, Goldcorp (now Newmont Goldcorp), Kirkland Lake Gold, Boliden and Nouveau Monde Graphite; OEMs Epiroc, Sandvik, Caterpillar, Volvo CE and BELAZ; and equipment and service specialists Siemens, ABB, GE Transportation (a Wabtec company). Presentations from Doug Morrison (CEMI), Marcus Thomson (Norcat), David Sanguinetti (Global Mining Guidelines Group), Erik Isokangas (Mining3) and Ali Madiseh (University of British Columbia), meanwhile, provided the R&D angle delegates were after.

The event was a truly global affair, attracting delegates and exhibitors from Africa, Australasia, Europe, North America and South America, all eager to hear about developments across the sector.

Bigger and better

International Mining Events is upping the ante for 2020, increasing the event capacity to 200 delegates and making plans for a possible site visit to witness electric equipment in action.

Talks from several miners, as well as global international companies, will again underpin the 1.5-day conference program, which will also expand to cover the use of renewable/alternative energy within the field.

There will, again, be opportunities for sponsorship and exhibiting, with several companies already in discussions about booking the prime opportunities for the event.

If you would like to know more about The Electric Mine 2020, please feel free to contact Editorial Director, Paul Moore ([email protected]) or Editor, Dan Gleeson ([email protected]).

In the meantime, we look forward to seeing you in Stockholm!
