矿井涌水严重威胁矿井的安全生产，为此建设矿井的自动化主排水泵控制系统非常重要。马兰矿针对矿井主排水泵控制系统存在的操作复杂 , 效率低 , 耗能大及自动化程度低等缺点 , 设计提出以 PLC 为控制核心的矿井主排水泵控制系统的改造方案 , 并对系统各元件进行分析 , 通过合理的程序设计实现对矿井主排水泵的全自动控制 . 通过对各个传感器进行分类 , 分别采取保障措施 , 确保传感器检测的可靠性。“,”mine water inrush is a serious threat to the safety of mine production, so it is very important to build the automatic main drainage pump control system. Malan mine for mine main drainage pump control system has the shortcomings of complex operation, low efficiency, high energy consumption and low degree of automation, design and put forward the transformation scheme of mine main drainage pump control system with PLC as the control core, and analyze the components of the system, realize the full-automatic control of mine main drainage pump through reasonable program design, Safeguard measures are taken to ensure the reliability of sensor detection.
