Abstract: Aiming at so many problems of coal mine drainage systems in China, such as the low automation, low operation efficiency, waste of human resources, high consumption of power and poor reliability, the unattended system of coal mine drainage is designed. S7-300 PLC control technology, Kingview technology and communication technology were applied to the system. By detecting the water levels and other parameters the pump station was unattended, “Peak, Valley and Flat time” was implemented, the rotation scheduling, remote monitoring and other functions were realized, improving the safety of the coal mine drainage system. The practice has proved that the system is reasonable in design, the operation is safe and reliable, failure rate is low and the power-saving effect is obvious.
