矿山采选企业是社会主义建设中的组成部分,是供应工业原料的基地。据现有全国黑色、有色矿山采选矿石量的不完全统计约为1.5×10~8t/y,若包括采矿的基建掘进、剥离工程量在内则约为2.7×10~8t/y。这数字尚未包括化学矿山,建材和非金属矿山。仅以1.5×10~8t采选量,节能10～20％来估算,节约能耗10～20亿度电是可以实现的。若包括上述其他矿山及基建掘进、剥离等工程量,则节能数字更为可观。
Mining mining enterprises is an integral part of socialist construction, is the base for the supply of industrial raw materials. According to the existing incomplete statistics on the amount of ores selected for mining in black and non-ferrous mines in the country, the incomplete statistics are about 1.5 × 10 ~ 8t / y. If the excavation includes mining, the amount of stripping works is about 2.7 × 10 ~ 8t / y. This figure does not include chemical mines, building materials and non-metallic mines. Only 1.5 × 10 ~ 8t mining capacity, energy saving 10 ~ 20% to estimate, saving 10 to 2 billion kWh of electricity is achievable. Including such other mines and infrastructure excavation, stripping and other projects, the energy saving figures are even more impressive.
