Abstract：Automatic control system of forced drainage was designed which was applicable to coal mine and can achieve monitoring and control of submersible pumps in a ground control room.The system takes programmable control technology as core,uses a variety of mine intrinsically safe sensors to real-timely monitor parameters such as water level,outlet pressure and submersible pump temperature,and realizes automatic control of forced drainage system through operation of diving electro hydraulic gate valve.The field industrial test results show that the system is running well and the PLC controls stably.
