我局九个矿,现有五十个主排泵房,共安装主排水泵307台,总装机容量17.27万千瓦。 1982年全局矿井排水用电量为27096.2万度。与1980年相比,排水效率提高8.33％,吨水百米电耗由0.523度下降到0.44度,全年节电4357.9万度,合人民币348.6万元(每度电按0.08元)。矿井排水用电量占我局总用电量35％以上。因此,在我局要搞好节电工作,必须先从矿井排水入手。近年来,我局在矿井排水节能方面,采取了以下一些主要技术措施。
I Bureau of nine mines, the existing 50 main pumping stations, a total of 307 main drainage pump installed, the total installed capacity of 172,700 kilowatts. In 1982 the global mine drainage electricity consumption of 270.962 million degrees. Compared with 1980, the drainage efficiency increased by 8.33%. The electricity consumption per 100 meters of water dropped from 0.523 degrees to 0.44 degrees. The electricity saving was 43.57 million degrees, equivalent to 3.486 million yuan (0.08 yuan per kilowatt-hour). Mine drainage electricity accounted for more than 35% of the total electricity consumption of our bureau. Therefore, in our bureau to do a good job saving, we must start with mine drainage. In recent years, our bureau has taken the following major technical measures in drainage energy conservation of mines.
