The coal mine drainage equip ment plays an important role to make the production normally and orderly. At present, domestic coal mine drainage system implement manual monitoring, namely the traditional relay control method.Feature of this method is that a large labor intensity, low reliability and stability,and complicated control circuit,it has not adapted to the needs of the development of coal.In this paper, design of the automatic drainage system is to make up for the shortage of the traditional relay control,it adopts PLC control with a combination of PC monitor to improve the safety of the work,and has a long service life, convenient maintenance, etc.
