The microseismic monitoring system primarily consists of seismometers, substations, and an analysis system. It is applied in areas such as dynamic load monitoring and early warning for shallow-buried working faces, rockburst/mine tremor monitoring and early warning, prediction and forecasting of large-scale roof pressure, optimization of safety measures for upward mining, and height detection of the “three zones.” This system enables real-time online monitoring of coal and rock mass failure events within the mine area, capturing phenomena with energy exceeding 100J, frequencies ranging from 0 to 1500Hz, and a dynamic range of 110dB. It facilitates stress field and fracture field inversion within the monitored area based on observation results. Through real-time analysis of microseismic event trends, the system provides effective dynamic assessment of rockburst hazards in key monitoring zones of the mine. The system features autonomous microseismic signal transmission capabilities, enabling automatic calibration of system parameters and significantly enhancing overall monitoring accuracy.
