干煤矿这一行的都知道:矿井开拓是在地下深处进行。由于水往低处流,井底必然有水,所以每个矿井都备有一套排水设施,它包括泵房、水仓、水泵、管道、电缆及供电变电设备,而泵房就是安装排水设施的蛧室。 完全封闭的泵房听起来很新鲜,其作用是指万一井淹了,而井下泵房仍然能保持干燥无水。要做到这点,必须在矿井设计时就明确这样几条措施:泵房与井底运输大巷有水闸门相隔;泵房内的汇水巷与水仓之间有高压闸阀控制;泵房内的裂隙溶洞都要注浆封 Dry coal mines in this line all know: mine development is carried out deep underground. Because of the low flow of water, the bottom of the well must have water, so each mine is equipped with a set of drainage facilities, including pump room, water tank, pumps, pipes, cables and power supply substation equipment, and the pump house is installed drainage facilities蛧 room. The completely enclosed pump room sounds fresh, its role is to see if the well is flooded and the downhole pumping station can still be dry and dry. In order to do this, several measures must be made when designing the mine: the pumping station is separated from the water gate by the bottom lane; the high pressure gate valve is controlled between the pumping lane and the water reservoir in the pumping station; Cracks inside the cave should be grouting seal
