Abstract:The international and domestic conditions of rock burst occurrences are summarized,and the development states of monitoring technique of rock burst are analyzed. It is found that rock burst occurs frequently as the mining depth increases and the influence scope of rock burst expands extensively. At present,there is not a valid monitoring technique and analyzing method,which can really forecast rock burst occurrence. For the purpose of the rock burst′s prediction,the geophysical method is introduced;and the mine microseismic monitoring
analysis system(MMAS) is proposed,which is composed of the microseismic monitoring system and numerical analysis system. The microseismic monitoring data,which is obtained by the microseismic monitoring system,can be transmitted by the internet to the numerical analysis system.Meanwhile,the data exchange between the monitoring system and the numerical analysis system can be implemented. By using the large-scale scientific calculation,the stress buildup,((((stress shadow)))),and stress transference of the stope,which is induced by the mining activity,are analyzed;and the rock burst occurrence is predicted. Meanwhile,the mine MMAS can also be used to predict other dynamical disasters of rock engineering.
