    Zijin’s 290 battery trucks at Wulagen: ventilation and design notes for mine planners

    Zijin’s 290 battery trucks at Wulagen: ventilation and design notes for mine planners

    First reported on International Mining – News

    30 Second Briefing

    Zijin Mining Group is rolling out a 290-strong battery electric truck fleet at its Wulagen lead-zinc mine in Wuqia County, Xinjiang, replacing conventional diesel haulage and creating one of the largest single-site BEV truck deployments worldwide. The mine, operated by Xinjiang Zijin Zinc, is shifting to fully electric underground and surface haul routes, relying on high-capacity battery packs and fast-swapping or fast-charging systems to keep utilisation high. For mine planners and geotechnical teams, the move reduces diesel ventilation demand and heat load, potentially allowing deeper or denser development with lower airflow requirements.

    Technical Brief

    • Xinjiang Zijin Zinc is phasing out diesel haulage at the Wulagen lead-zinc operation in Wuqia County.
    • Centralised BEV deployment allows standardised fire suppression, isolation and high-voltage lock-out procedures across the fleet.
    • Removal of diesel engines reduces underground NOx and particulate exposure, easing compliance with occupational exposure limits.
    • Lower exhaust heat and fumes cut reliance on auxiliary ventilation fans in headings and loading bays.
    • Battery truck operation reduces fuel storage and transfer on site, shrinking fire and spill risk envelopes.
    • Standardised electric drivetrains improve braking control on declines, reducing runaway truck risk on ramps.
    • Large-scale BEV use at Wulagen provides a reference case for Chinese regulators updating mine safety guidance on electric fleets.

    Our Take

    Zijin Mining Group also appears in our coverage via CATL’s 30 billion yuan mining subsidiary plan, signalling that Zijin is positioning itself not only as a base metals producer but as a relevant player in the broader battery raw materials ecosystem that underpins electrification projects like the Wulagen truck fleet.

    Among our 1213 Mining stories, large-scale battery-electric haulage is still concentrated in a few high-profile copper and iron ore operations, so a 290-truck deployment at a lead-zinc operation in Xinjiang indicates that BEV haulage is now moving into more conventional underground and polymetallic settings where ventilation and diesel costs are critical drivers.

    Applied Intuition’s Dana platform: integration and testing notes for mine robotics

    Applied Intuition has launched Dana, an agentic platform for building, testing, deploying and operating physical AI systems, targeting applications such as autonomous haulage, drilling automation and robotic inspection in mines. The platform combines agentic AI with the company’s existing simulation, scenario generation and validation toolchain, allowing developers to iterate control policies and perception models in software before field deployment. For mine operators and OEMs, Dana is positioned to shorten integration cycles between virtual testing and on-site commissioning of AI-enabled mobile equipment and fixed-plant robotics.

    Mt Holland spodumene expansion: ore sorting and cost impacts for mine planners

    Wesfarmers and SQM have jointly approved a final investment decision to expand the Mt Holland lithium project in Western Australia, adding a new integrated ore sorting facility alongside the existing mine and concentrator. The project, operated by Covalent Lithium, will double spodumene concentrate output and is expected to materially reduce unit operating costs while accelerating cash flow from the operation. For mine planners and process engineers, the key change is the upstream ore sorting step, which should improve feed grade and reduce downstream milling and flotation load.

    ICMM water risk study: key implications for mine design and tailings teams

    Nearly two-thirds of global mining and metals facilities are sited in areas of significant physical water risk, according to ICMM’s new Global Mining and Metals Water Dataset. The analysis also finds that competition for water between mine sites and other industrial and domestic users is the dominant physical risk driver, rather than solely hydrological scarcity. For geotechnical and processing teams, this points to tighter constraints on dewatering, tailings water balances and make-up water allocations, with permitting and community relations becoming critical design inputs.
