矿山井下排污水系统自动化应用研究

Research on application of automation in underground drainage system of mines

矿山井下水仓排水系统多采用自吸式排污泵进行排放污水,排水期间需要人员手动开启水泵及阀门,并且需对水泵的排水状况进行实时监管,否则当水仓内污水排空时,若不及时关闭水泵及阀门则会引发电机烧毁、泵头机械密封损坏等一系列故障。针对这一现状,本文对矿山井下水仓排污水系统进行自动化控制改造,在原有排水系统的基础上增设电动偏心半球阀、水位传感器、搅拌机以及电气控制系统等相关部件,利用水位传感器的信号电动控制水泵的启停以阀门的开关,同时优化安装工艺并进行调试,实现了排水自动化。经过对比分析,系统故障率下降了60%,现场使用效果显著,减轻了维修人员的工作量,切实提高了矿井排水的安全性以及稳定性。

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.
