65 extended range electric mining trucks pass through the Gobi mining area in an orderly manner, leaving a continuous green energy trajectory when the wheels roll over the desert dirt road. The cumulative operating time of this batch of self-developed equipment by China Railway Chang'an Heavy Industry has exceeded 300000 hours. Nowadays, hundreds of electric wide body dump trucks have landed in more than ten open-pit mines in China, covering mainstream vehicle models ranging from 95 to 135 tons. Multiple versions of pure electric, extended range, battery swapping, and unmanned driving are operating simultaneously, moving from single point pilot to cross provincial and contiguous large-scale operations. With the advantages of power recovery, unmanned control, and flexible intelligent manufacturing, mining operating costs and carbon emissions are simultaneously reduced.

Green Energy Strong Drive Mining Area Operation

Heavy duty vehicles at Jingxing Mine in Hebei Province can easily climb steep slopes, with a maximum climbing ability of 35% better than the industry average standard of 25%. The vehicle can operate continuously all day long after being charged for one hour, without the need for continuous braking when going downhill. The energy recovery device converts potential energy to recharge the battery, and after one downhill trip, the power does not decrease but increases, completely bidding farewell to the roaring exhaust of fuel vehicles.

Intelligent unmanned efficient mining

Thirty unmanned electric mining trucks in the Zhundong mining area of Xinjiang independently completed transportation and loading and unloading, and the staff retrieved real-time vehicle position and load warning data from the remote control room. The six dimensional safety protection system automatically controls the ramp speed limit and emergency steering. Ten unmanned vehicles put into operation in October last year have traveled over 50000 kilometers and transported 600000 tons of ore. Multiple electric vehicle models are paired with intelligent cloud platforms, and the dynamic control system is adapted to the road conditions and slopes of various mining areas. It operates 24 hours a day without interruption, and the overall operational efficiency is improved by 11%. Keywords: electric wide body dump truck, intelligent manufacturing of equipment

Intelligent manufacturing reduces carbon emissions and increases income in both directions

The Xi'an Yanliang intelligent production line has connected the entire R&D and production process, with multiple intelligent systems operating in coordination. Logistics energy consumption has decreased by 32%, production capacity has increased by 50%, and the annual output of equipment is 2000 units. In the first half of the year, the shipment volume of new energy vehicle models increased by 35% year-on-year. Data from various regions shows that the annual cost savings of five electric mining trucks exceed three million yuan. The total annual carbon reduction of vehicles in operation nationwide is equivalent to a forest carbon sequestration scale of two thousand acres. The low-cost and zero pollution plan promotes the comprehensive replacement of fuel equipment in mines.Editor/Min Jing
