Yutong Electric Mining Trucks Bring Green Transformation to an Open-Pit Coal Mine in a Severe Cold Region

An open-pit coal mine in Northeast China, marked by brutal cold, snow, mud, and long heavy-haul slopes, placed a bulk order for 100 high-capacity Yutong YTK145E electric mining trucks in 2025. It is now the region’s largest new energy mining truck fleet and a replicable model for cold-climate mine electrification.

Low temperatures have long been a barrier to electric mining trucks, causing range loss and operational instability. After reviewing successful long-term operations at other cold-region sites, the mine selected the Yutong YTK145E, built on a mining-specific electric platform with dedicated batteries, four-plug fast charging, intelligent thermal management, and regenerative braking.

The site faces more than three months of winter with lows dipping below -20°C. Haul distances run 4 to 10 kilometers, with loaded uphill grades averaging 5%. Yet the trucks are holding up impressively: each one logs up to 32 trips per day in winter, and in summer’s muddy conditions, they still manage a steady 20 trips daily. The fleet is running at a 96% uptime, with over 310 operating days a year.

An on-site maintenance team runs preventive checks to reduce downtime, while an intelligent fleet management platform enables pre-trip inspections, remote battery preheating, smart dispatch, and energy analytics.

The stable operation of these 100 trucks has shattered the industry’s long-held belief that electric mining trucks cannot scale in cold regions. It cuts costs, boosts efficiency, and reduces emissions, offering a proven electrification model for Northeast China and other high-latitude open-pit mines on the path to safe, efficient, low-carbon intelligent mining.
