能源是发展国民经济,实现四个现代化,提高人民生活水平的重要物质基础,因而,节约能源具有不可忽视的重要意义。对于地下矿山,其采矿能耗主要表现在电耗上,而耗电设备主要又包括压缩空气、通风、排水、运输,提升和其它辅助设施。这些设施耗电在整个采矿耗电中所占的比重大约是:压缩空气占30～55％;通风占21～39％;排水占10～35％;运输提升占10～30％;其它占 Energy is an important material basis for developing the national economy, realizing the four modernizations and raising the living standards of the people. Therefore, saving energy is of great importance that can not be ignored. For underground mines, the energy consumption of mining is mainly manifested in electricity consumption, while the power consumption equipment mainly includes compressed air, ventilation, drainage, transportation, upgrading and other auxiliary facilities. The consumption of electricity in these facilities accounts for about 55% of the total power consumption of the mining area; ventilation accounts for 21-39%; drainage accounts for 10-35%; transport promotion accounts for 10-30%; other accounts for
