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¡äs 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. |
