The zero-carbon mine solution is oriented toward the integrated development of coal and new energy resources. It adopts a location-specific approach to build a four-dimensional collaborative system of "green energy supply + production energy-saving retrofitting + resource comprehensive utilization + digital-intelligent management and control", so as to realize green and low-carbon development across coal excavation/stripping, mining, washing, storage and transportation. For underground coal mines, given the characteristics of idle subsidence land, high energy consumption in key production links, significant gas emissions and abundant waste heat resources, priority will be given to the development of integrated PV-storage-charging technologies, energy-saving retrofitting technologies for key energy-consuming links, comprehensive utilization technologies for gas, coal gangue, mine water and waste heat, as well as a digital energy-carbon management and control platform. For open-pit mines, targeting the issues of idle waste dumps, high fuel consumption and carbon emissions of traditional mining trucks, and weak energy-carbon management and control, focus will be placed on developing integrated PV-storage-charging technologies, all-electric mining trucks with auxiliary hill-climbing technologies, large-scale environmentally sound disposal technologies for coal gangue, comprehensive wind-solar-thermal utilization technologies, and a digital energy-carbon management and control platform.
