CATASTROPHE THEORY ANALYSIS OF MINING FAULT ROCKBURST UNDER NONUNIFROM SURROUNDING PRESSURE
非均匀围压下矿井断层冲击地压的突变理论分析

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.
