Sandvik Begins Trials of BEV Underground Mining Truck at Sunrise Dam

Following a three-party agreement between AngloGold Ashanti, Barminco and Sandvik, the Sandvik TH665B battery-electric underground mining truck begins trials at Western Australia’s Sunrise Dam mine.

Under an agreement between mine owner AngloGold Ashanti, hard rock underground contract miner Barminco and Sandvik, the gold operation near Laverton began trialing the prototype 65-metric-ton Sandvik vehicle on September 14 – with the wider industry keeping a close eye on the results. As well as producing zero diesel emissions underground and generating 80 percent less heat, the Sandvik TH665B is expected to be up to 25 percent faster on a 1:7 ramp than regular diesel trucks.

Darren Kwok, Head of Electrification and Technology for Barminco’s parent company Perenti, said he is excited to see just what the new Sandvik BEV can achieve.

“As a business we are focused on how we can support our clients to decarbonize their mines and trialling equipment to support this is a critical part of our strategy. Battery-electric vehicles (BEVs) not only have the potential to lower carbon emissions, they can also improve the underground environment for mine workers and boost the efficiency of operations. We’re extremely pleased that the first Sandvik TH665B to be built has come to Sunrise Dam for real world trials with us and AngloGold Ashanti. With the longer haul ramps and the harsh Australian operating conditions, it will be put to the test. We’re looking forward to trialing the Sandvik TH665B and putting it through its paces.”

said Kwok.

“We’re delighted to be working with AngloGold Ashanti and Barminco on these trials. The data that we gain from seeing the prototype interacting with Australian conditions will be invaluable as Sandvik continues to develop its battery-electric range and as the Sandvik TH665B moves into commercial production phase.”

said Andrew Dawson, Business Line Manager for Load and Haul at Sandvik.

Lithium-Iron Phosphate battery

The local mining industry got its first glimpse of the Sandvik TH665B when it made its Australian debut at the World Mining Congress in Brisbane, earlier this year. Developed on the back of more than 40 years of electrification experience, the machine uses lithium-iron phosphate (LiFePO4 or LFP) battery technology. The electric driveline delivers 630 kW (858 hp) of continuous power, allowing for high acceleration and shorter cycle times. It produces zero diesel emissions underground and significantly less heat than a comparable conventional truck.

Sandvik will have four local technicians on site who will support the machine throughout the trial and will provide operator and maintenance training to the teams on site.

Kwok said Barminco’s parent company, Perenti, is working in collaboration with a number of partners towards a fully electrified, zero CO2 and zero diesel particulate mine.

“We believe BEVs like this one have a critical role to play in the electric mines of the future and supporting decarbonization. In this trial, two areas we will be monitoring closely are the ramp speed and the contribution to emissions reduction. Sandvik has said that a fully loaded Sandvik TH665B will be up to 25 percent faster on a 1:7 ramp than a conventional diesel truck – so we will be keen to see that in action.”

Battery self-swapping

Dawson said another key feature of the Sandvik TH665B is battery self-swapping.

“It is equipped with AutoSwap, our patented self-swapping system which makes the battery changing process extremely fast and easy, usually taking only three minutes. It also allows the operator to stay in the cabin during the process, and there’s no need for major infrastructure like overhead cranes.”

said Dawson.

Dawson said Sandvik BEVs offer a range of economic, sustainability and health and safety benefits. From an economic perspective, they can increase productivity and muck pile performance, reduce cycle times, and lower operating costs and ventilation and cooling costs. In terms of sustainability, BEVs can reduce greenhouse gas emissions, increase energy efficiency and promote fuel independence.

“Finally, there are major benefits from Sandvik BEVs for operator health and safety thanks to reduced diesel particulates, less noise and vibration and a reduction in heat generation.”

said Dawson.

Both AngloGold Ashanti and Barminco are proactive about increasing mine efficiency, improving conditions and safety for mine staff, and reducing emissions. AngloGold Ashanti’s 2022 Sustainability Report released earlier this year charted a course to achieve net zero Scope 1 and 2 GHG emissions by 2050. The company aims to achieve this with a combination of renewable energy projects, fleet electrification and lower-emission power sources.
