Constructing an Intelligent Mining System for Coal Mine Fully Mechanized Mining Face Based on Digital Twin Technology
Due to the fact that the fully mechanozed mining production process is a black box process,in order to achieve less human and unmanned control,digital twin technology based on sensor data is needed to convert the downhole real scene into a digital scene in real time,so that the system can better monitor,analyze,and control the fully mechanized mining equipment.Using a 2D and 3D lightweight engine and a unified spatiotemporal database,based on the shearer real-time absolute geological coordinates provided by the domestic inertial navigation system,combined with the state parameters of the working face equipment,a digital twin working face that can characterize the working status of the equipment in real size is constructed.Conduct technical verification and engineering practice of relevant researches in Zhaolou and Dongtan Coal Mines of Shandong Energy Group,providing a real-time and accurate visualization operation system for intelligent mining research and a powerful tool for intelligent mining of the working face.
