煤矿井下主排水系统工艺流程及其自动控制系统设计

摘要

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.%介绍了煤矿井下主排水系统的相关工艺流程,总结了煤矿井下主排水系统的特点,设计了一套煤矿井下主排水自动控制系统,详细介绍了该系统的组成和软件控制策略.该系统通过井下控制主站的决策控制对排水设备的运行过程和运行状态进行自动控制与监测,使排水设备达到最佳工作状态;同时可根据峰谷分时电价、水仓水位及涌水量情况控制水泵的启停,从而达到有效节约能源、降低劳动强度、延长设备使用寿命的目的.
