排水系统是煤矿井下的关键系统之一,对于排出煤矿井下涌水,保障煤矿安全生产具有重要意义。针对现有矿井排水系统智能化水平较低、系统耗电量较大等问题,提出一种矿井智能化排水系统,系统以可编程控制器PLC为核心,通过模糊控制算法分析井下水仓的液位和涌水变化率,得出排水系统的最佳运行方案,并将该模型结构输入到PLC中,结合排水主管路的流量、水泵压力等数据,达到水泵房智能运行与避峰填谷的目的,并通过随机森林算法解析水泵的振动信号,分析水泵的故障类型和健康状态。该系统有效地提升了井下排水效率,降低了设备磨损率,减少了煤矿排水系统电能消耗,对煤矿智能化排水系统设计具有一定的参考价值。

Drainage system is one of the key systems in coal mine, which is of great significance to discharge gushed-in water and ensure the safety of coal mine production. Aiming at problems such as low intelligence level and high power consumption of existing mine drainage system, an intelligent mine drainage system is proposed. The system takes PLC as the core to analyze the liquid level and gushed water change rate of underground sump through fuzzy control algorithm. The optimal operation scheme of the drainage system is obtained, and the model structure is input into the PLC, which is combined with the flow of the drainage main road, pump pressure and other data, to intelligently operate the water pump house and achieve peak load shaving; the random forest algorithm is used to analyze the vibration signal of the pump, and analyze the fault type and health state of the pump. The system can effectively improve the efficiency of underground drainage, reduce the wear rate of equipment, and reduce the power consumption of coal mine drainage system, which has certain reference value for the design of intelligent drainage system in coal mine.
