我矿东矿车间采场由1653水平到1460水平,其开采深度已达193m采场矿坑的排水工作也就非常重要。现在的水泵采用200D1-43×7离心式高压清水泵,抽水量为288m3/h,及时把水排掉,保证电动挖掘机的作业环境。但若雨水过大,水泵的排水量就明显不足,很容易造成水泵被淹,电动机被烧毁的事 The mine stope in our mine is from 1653 level to 1460 level, and its mining depth has reached 193m. It is also very important for mine drainage work to be conducted. Now the pump uses 200D1-43 × 7 centrifugal high-pressure water pump, pumping capacity of 288m3 / h, in time to drain the water to ensure that the operating conditions of electric excavators. However, if the rain is too large, the pump displacement is obviously insufficient, it is likely to cause the pump flooded, the motor is burned
