Abstract:Aimed at goaf and rock burst phenomenon in Lingnan Gold Mine, the seismic activity characteristics of deep excavation process are studied with microseismic monitoring technology. Consideration practical engineering conditions and sensor diagonal space network solution, digital multi-channel seismic monitoring system is established, which has the function of advanced and rich seismology quantitative analysis, and the rock activities can be studied. It is analyzed based on the waveform changes of rock mass. The results of the study provides important reference for better understanding and analyzing the rock deformation under complicated stress conditions and the mechanism of instability induced by their seismic activity.
