矿山井下涌水及生产废水一般都汇集于矿井底部水仓,由排水泵组合排出地表,并经处理后汇入地表水域。井下排水系统是矿山安全生产的关键设备,也是矿山生产的主要能耗设备。一般其电耗占井下矿山总电耗的17.5%～40%, Underground mine water and wastewater production are generally collected at the bottom of the pit water tank, drainage pump combination discharged from the surface, and after treatment into the surface waters. Underground drainage system is the key equipment of mine safety production, and also the main energy consumption equipment of mine production. Its power consumption accounts for 17.5% ~ 40% of the total power consumption of underground mines,
