Abstract: In a mine, with the increase of mining depth, the problem of ground pressure gradually becomes prominent, and dynamic disasters such as roof caving, pillar wall and other rock mass occur during mining. At the same time, there are cross-border mining activities of surrounding mines, and unknown mining operations affect the stability of rock structure system. Therefore, the microseismic monitoring system was established to identify and locate microseismic and blasting events through data processing. Based on the monitoring data of a certain period of time, the temporal and spatial activity law of rock mass fracture activity was summarized, the stress distribution characteristics of surrounding rock in the mining area was analyzed, and the time and location of cross-border mining operation was mastered. This monitoring and analysis method can be applied and popularized in the mine pressure control in the future.
