地下矿山排水用电占采矿总用电量的50％左右(涌水量较大的矿山达70％),井下排水用电是采矿成本的重要组成部分。因此,降低排水成本,对矿山的降本增效有重要意义。 以前,矿山企业对排水系统设备经济运行分析侧重于水泵效率、传动效率、电机效率、电路效率与管道效率等因素之间的最佳配合,也就是将1 t水提升100 m所需用的电量最少,达到降低能耗减少排水总用电量的目的。但是现在供
Underground mine drainage electricity accounts for about 50% of the total electricity consumption of mining (70% of the larger gushing water mines), underground drainage electricity is an important part of mining costs. Therefore, reducing drainage costs, reducing costs and increasing efficiency of the mine is of great significance. In the past, analysis of economic operation of drainage system equipment by mining enterprises focused on the best match between pump efficiency, transmission efficiency, motor efficiency, circuit efficiency and pipeline efficiency, that is, the amount of electricity required to lift 1 t of water by 100 m At least, to reduce energy consumption to reduce the total drainage electricity purposes. But for now
