Core Insights - The first batch of domestically developed 120-ton pure electric mining trucks has been put into operation at the Zahahe'er Coal Industry Company, marking a significant advancement in the large-scale application of electric vehicles in open-pit mining [1][3]. Group 1: Technology and Performance - The electric mining trucks are powered by lithium iron phosphate batteries, capable of working continuously for over 4 hours after a 1-hour charge, achieving a daily rock and soil stripping volume of 18,000 cubic meters [3]. - Cumulatively, these trucks have completed nearly 2.8 million cubic meters of stripping, equivalent to the volume of 1,096 swimming pools [3]. - Compared to diesel trucks of the same tonnage, operational costs are reduced by 63%, energy consumption by 40%, and annual carbon emissions are decreased by over 7,500 tons, equivalent to planting 400,000 fir trees [3]. Group 2: Innovation and Safety - The development of these trucks involved overcoming challenges related to battery performance in low temperatures and heavy loads, resulting in five national patents for technologies such as multi-branch charging and discharging, battery cooling, and energy recovery [3][5]. - A self-developed "vehicle intelligent security system" has been added to enhance safety, featuring collision warnings, real-time monitoring, speed alerts, and driver behavior analysis [5]. Group 3: Future Goals - The Zahahe'er Coal Industry Company aims to accelerate the transition from oil to electric mining, expand the application of pure electric mining trucks, and enhance the efficiency of new energy equipment, focusing on building a "green electricity + electric mining truck" energy model to promote green transformation [5].
