Agnico Eagle is to explore the benefits of battery-electric underground technology after receiving a Sandvik LH518B underground loader at its Fosterville gold mine, in Victoria, Australia, to be tested in the second half of 2022.

The Fosterville operation, 20 km from Bendigo, will become the first mine on Australia’s East Coast and only the second in the country to take delivery of the new Sandvik loader (the first being Gold Fields’ St Ives operation in Western Australia). Featuring advanced lithium-iron phosphate-based battery technology, the LH518B produces zero underground exhaust emissions and emits significantly less heat than its diesel counterparts.

Rob McLean, who was Fosterville’s Chief Mining Engineer at the time, announced plans for the operation to trial the Sandvik LH518B at the IMARC Online event in November 2020. He said the trial – originally slated for 2021 – was 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.

After the new machine arrived on site, Fosterville Gold Mine’s General Manager, Lance Faulkner, said: “As a company, we’re committed to exploring new technologies to further enhance our extensive health and safety programs and to fully integrate sustainability into everything we do. And so, we’re delighted to be putting the LH518B into service at Fosterville. We’re interested to see just what kind of difference it can make in terms of efficiency and the underground working environment, and we look forward to working closely with Sandvik.”

Featuring a 600 kW drivetrain, the Sandvik LH518B allows for higher acceleration than conventional loaders as well as fast ramp speeds, resulting in short cycle times, Sandvik says. Courtesy of its space-efficient battery system and driveline, it is the most compact 18-t loader on the market, capable of fitting in a 4.5 x 4.5 m tunnel, the company claims.

Andrew Dawson, Sandvik Business Line Manager for Load & Haul, says that with the advantages Sandvik battery-electric vehicles (BEVs) bring in terms of safety, efficiency and sustainability, it’s no surprise they are gaining popularity among underground operators.

“By trialling the Sandvik LH518B, Agnico Eagle is putting itself at the forefront of this emerging technology and showing its environmental credentials,” he says. “Not only does the loader produce no underground emissions and significantly reduced heat, but it also delivers new levels of productivity. It all makes for a safer, more comfortable, more controlled underground environment.

Fosterville’s Faulkner says another attractive feature of the Sandvik LH518B is the ability to quickly and simply swap out the battery cage. Sandvik’s AutoSwap technology allows for a depleted battery to be offloaded and a fully charged one loaded in as little as six minutes, with no need for lifting infrastructure.

“It’s crucial that new technologies are sustainable and safe, but also that they contribute to the efficiency and smooth running of our mining operation,” he said. “From what we have heard about the new Sandvik loader, it will deliver on all three fronts.”

Kate Bills, Sandvik Australia General Manager – Sustainability, says the LH518B is a reflection of Sandvik’s determination to lead the market for safe, productive and climate-efficient mining equipment.

“Sandvik is putting its money where its mouth is by investing in battery electric vehicles and other technologies that are helping customers achieve their sustainability goals,” she says. “Customers both globally and in Australia are increasingly looking for these kinds of solutions and we are proud to be providing them.”

Byrnecut to use six Sandvik 18-t-payload BEVs at OZ Minerals mines

Leading Australia-based contract miner Byrnecut is embracing the many benefits of battery-electric vehicles (BEVs) by purchasing six Sandvik battery-powered loaders with AutoMine® for use at OZ Minerals’ operations in South Australia.

Under a deal with Sandvik Mining and Rock Solutions, Byrnecut will take delivery of the LHDs in 2023 and 2024 for use at the Prominent Hill copper, gold and silver mine, south-west of Coober Pedy, and the Carrapateena copper and gold mine, north of Port Augusta. Byrnecut has been engaged by OZ Minerals to provide underground mining services at the mines and currently has a fleet of Sandvik LH621i loaders equipped with autonomous solutions operating on both sites.

“We’re excited to be leading the way with battery-electric vehicles in Australia by putting these six Sandvik loaders into service over the next two years,” Max Woods, Asset Manager for Byrnecut, said. “Not only will the use of electric vehicles significantly improve the working environment underground, but it will also help our customers to work toward their emissions reduction goals – something that is increasingly important in the mining sector.”

Woods says the purchase of the electric loaders is part of Byrnecut’s commitment to explore and embrace new technologies that make its operations safer, more efficient and more sustainable.

“Eliminating emissions from loaders from the underground environment helps us create a better workplace, as does AutoMine technology that enables operators to work from comfortable remote control rooms,” he said.

Another major benefit to Byrnecut is the anticipated increased performance the new loaders could provide, Sandvik says.

The company worked closely with Sandvik prior to purchase to model various application scenarios, including both manual and automated operation.

“We’re expecting the loaders to provide greater throughput in both manual and automated modes while delivering a similar total cost of ownership per tonne delivered to their predecessors,” Woods says.

The new Sandvik loaders are also expected to bring major cost savings across their entire lifecycles, according to Woods. They are likely to require fewer replacement parts than their predecessors, and servicing is also more efficient and simpler.

Sandvik 18-t battery loaders are the most compact on the market, according to the OEM. The powerful electric motors, innovative electric driveline and the smaller tyres on the rear compared with the front, result in a small machine size, high payload with good visibility and unmatched speeds.

Battery machines produce no underground exhaust emissions and significantly less heat than traditional diesel engines, supporting the mines to reach sustainability targets, through reduced CO2 emissions.

Andrew Dawson, Business Line Manager for Load & Haul at Sandvik, praised Byrnecut for helping to pioneer the use of BEVs in Australia.

“The first Sandvik battery-electric loaders only began arriving in the country about a year ago, and the interest has been extremely strong,” he says. “We’re very pleased that Byrnecut and Oz Minerals see the benefits of this technology and is demonstrating it to the rest of the industry. We have always had an excellent working relationship with Byrnecut and look forward to cooperating with them throughout the roll-out and beyond.”
