【Abstract】 In this paper, the RFPA developed by CRISR (Center of Rockburst and Instability Seismicity Research) is used to simulate the whole process of occurrence of rockburst during deep mining. The simulated results reproduce the mechanism of rockburst and failure seismicity from the point of stress field distribution. The numerical simulation is based on the rockburst problems during deep-cave excavation in HongTouShan Cooper Mine. The results indicate that the occurrence of rockburst is foreseeable, and a new numerical method is brought forward.更多还原
