The drainage system of mining well water storage often uses self-suction sewage pumps to discharge sewage. During the drainage period, personnel need to manually open the water pump and valves, and real-time monitoring of the drainage status of the water pump is required. Otherwise, when the sewage in the water storage tank is discharged, if the water pump and valves are not closed in time, it will cause a series of faults such as motor burning and mechanical seal damage of the pump head. In response to this situation, this article has carried out automation control transformation on the sewage discharge system of the mining well water storage tank. On the basis of the original drainage system, relevant components such as electric eccentric hemisphere valve, water level sensor, mixer, and electrical control system have been added. The signal of the water level sensor is used to electrically control the start and stop of the water pump and the switch of the valve. At the same time, the installation process has been optimized and debugged, achieving drainage automation. After comparative analysis, the system failure rate has decreased by 60%, and the on-site use effect is significant, reducing the workload of maintenance personnel and effectively improving the safety and stability of mine drainage.
