Abstract:Ground pressure disaster is one of the security problems which must meet in almost all mines. This paper first introduces the current research situation of microseismic monitoring system at home and abroad, and then through build a set of microseismic monitoring system to monitor the stability of goaf in Xinglong phosphate mine, and based on the monitoring data for a period of time, on the ground pressure activities filling process are analyzed, the analysis results show that it is necessary to carry out the microseismic monitoring in the ground control process of mining goaf. Finally, it suggests that it would be must to carry out the research on microseismic monitoring in the mining and excavation construction process and the treatment of goaf, because it can strengthen the rockburst risk real-time monitoring and reduce the loss of personnel and equipment.
