Study on mechanism of rock burst induced by mine quake
According to the elastic wave theory,the formula of stress wave induced dynamic disturbance generated by the mine quake was deduced,and the theoretical model of rock burst was established so as to deduce the occurrence theory of rock burst;the process of rock burst induced by mine shock was simulated by using abaqus numerical simulation technology;the occurrence conditions of rock burst were investigated when the surrouding rock roadway was subjected to the action of static-dynamic load superposition.According to the measured data of the rock burst induced by a mine quake in reality,the theory of rock burst induced by mine quake was verified.The simulation results showed that when the the static stress on the surrounding rock roadway was too high and reaches the critical plas-tic zone,small mine quake can cause the occurrence of rock burst in the surrounding rock roadway.
