The monitoring system of rock mass stability and activity characteristic was established using the microseismic monitoring technology in view of the problem that the dynamic disaster of ground pressure was easy to occur in the process of deep mining. The monitoring network was set up according to the actual characteristics of the mine and the wave velocity was corrected by the method of fixed-point blasting. A monitoring network with a positioning error of 10 m was established finally. The waveform of the monitoring data was picked up and the temporal-spatial evolution characteristics of microseismic events were analyzed, the microseismic events increased greatly and in a high level, the spatial distribution was concentrated highly, the potential dangerous areas were delineated. The research results can provide references for the investigation of rock mass stability monitoring in underground engineering.
