Application research of intelligent drainage system in coal mines
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.
