Study on the dynamic response and the hazard of rock burst under the influence of fault slip

In the process of coal mine production, rock burst accidents near faults occur frequently. order to further reveal induced mechanism fault slip burst, a numerical simulation method for dynamic calculation under influence mining is proposed, and law response characteristics stope are studied. The study shows that with working face getting closer fault, activity number high-energy microseismic events increase significantly, load has significant impact on vibration velocity abutment stress mass stope. Under effect strong load, in area peak undergo plastic failure release large amount energy, potential high. evaluation index I cd hazard passing through analyzed. research results provide theoretical basis revealing assessment bursts.
