摘　　要：按Mises增量理论 ,将提出的均匀围压下矿井断层冲击地压的突变理论分析推广到非均匀围压下的断层冲击地压分析 ,得到非均匀围压下的断层失稳半错距和弹性能释放量表达式。对由于断层失稳导致围岩产生的荷载。According to the Mises increment theory, the analysis with catastrophe theory on the mining fault rockburst under uniform surrounding pressure is extended to the one under non uniform surrounding pressure. The expressions of fault offset and release value of elastic energy under non uniform surrounding pressure are obtained. Besides, the effects of load and displacement are analyzed also for the surrounding rock around the fault rockburst.
