ANALYSIS OF ROCKBURST PROCESS FOR NONCONTINUOUS AREA IN MINES

In this paper, on the basis of analysing the phenomena for fault in mines, the rockburst process is described by superposition for vibration in rockmass and sliding in noncontinuous area ; the stable andinstable slidings for fault is presented, and more and more instable vibration is analysed, When rockburstoccears in fault area, the displacement for rockmass is superposition of rigid sliding and vibration. The affectfators and reasons are pointed out.
