摘要
通过深入小煤矿和到井下水泵房深入调查,分析发现有底阀排水系统存在诸多问题,可以利用现有的设备添加一些附件和改进现有水泵控制电路,使水泵实现无底阀自动化排水,从而实现泵房无人值班看守运转。这样,既能节约能源消耗,又能提高小煤矿企业的经济效益。
Based on a deep investigation in the small scale coal mine and underground water pump room, the autours discuss and point out many problems existing in the drainage system with bottom valve. The benefits of a non-bottom-valve system without personel on du（y can be acquired via adding some accessories to an existing equipments and improving the electric circuit of an existing water pump control. In such a way, not only can the fuel consumption be reduced, but the economic efficiency of the small scale coal mines will be improved.
