Abstract:A ground pressure monitoring system was established based on microseismic monitoring technology to evaluate the ground pressure activities in a gold mine comprehensively. The wave velocity correction results of the monitoring system were verified, and the positioning error was 3.9 m, which meted the requirements of safety monitoring. The concentration area of microseismic events coincided with the production concentration area. The time series analysis of microseismic event activity rate, energy index, and cumulative apparent volume revealed the evolution characteristic of stress-energy in a rock mass., It edshowed that the apparent stiffness and stress level of the rock body hassmall, and microseismic events of small magnitude were the main ones through the analysis of power-law characteristics of microseismic event parameters. A comprehensive evaluation of ground pressure activity was carried out combined with the analysis results of microseismic parameters finally. The research results were of certain reference significance for the evaluation of ground pressure activity in similar mines.
