en.Wedoany.com Reported - BHP, Rio Tinto and Caterpillar have launched field trials of two Cat 793 XE Early Learner battery-electric mining trucks at the Jimblebar iron ore mine in Western Australia's Pilbara region.
The project is a joint effort between mining companies and equipment manufacturers, aiming to explore viable pathways for reducing greenhouse gas emissions in large-scale mining operations. The tests began after safety verification and controlled trials were completed at Caterpillar's test site in Tucson, USA. The two vehicles arrived at the Jimblebar mine late last year and have since accumulated over 100 hours of operation and completed more than 200 test cycles. Initial data collected is being used to assess the technological maturity, infrastructure requirements, and commercial viability of battery-electric mining trucks.
Geraldine Slattery, President of BHP Australia, stated that investing in the technology and operations of a battery-electric mining truck fleet in the Pilbara region is key to achieving decarbonization goals. This trial helps advance the necessary technology and enhances the company's understanding of how to scale up within its operations, covering charging infrastructure, energy management, and integration into a safe and efficient production system. BHP remains on track to achieve its target of reducing operational greenhouse gas emissions by at least 30% by fiscal year 2030 (FY2030) compared to FY2020 levels.
The Jimblebar mine currently hosts two of the seven Caterpillar Early Learner battery-electric mining trucks being tested globally. The trials focus on static and dynamic charging technologies, including experiments with high-power charging solutions designed for large-scale mining needs. The next phase will test a dynamic charging system that charges the trucks while they are in motion.
Representatives from BHP, Rio Tinto, Caterpillar, and WesTrac, along with Western Australian Premier Roger Cook and Minister for Mines and Petroleum David Michael, observed the vehicles during a demonstration at the Jimblebar mine. Participants believe the trial is a significant step in addressing the decarbonization challenges of mining operations. Earlier this year, BHP and Rio Tinto announced plans to jointly develop their adjacent Yandicoogina and Yandi mines, with an expected total production capacity of 200 million tonnes of iron ore.
