Abstract
The paper introduced related technical process of coal mine main drainage system, summarized characteristics of coal mine main drainage system, designed automatic control system of coal mine main drainage, and introduced composition and software control strategy of the system in details. The system can control and monitor operation process and state of drainage devices automatically with decision-making of main control station to make drainage devices achieve the best working condition. Meanwhile, the system can control start and stop of water pump according to TOU tariff, water level of water sump and water inflow condition to save energy effectively, reduce labor intensity and extend service life of drainage devices.
