Based on the stress distribution characteristics of rock burst multiple sites,the criterion of horizontal stress inducing layer dislocation rock burst was established.Accordingly,the influencing factors were analyzed.The analysis results indicate that the stress condition,edge of elastic zone depth,supporting strength,and the friction angle and cohesion among coal stratum,roof and floor are sensitive factors.By introducing double-couple model,the layer dislocation rock burst was explained and the energy radiation characteristics were analyzed.The SOS micro-seismic monitoring system was applied to observe the rock burst hazards about a mining face.The results show that P- and S-wave energy radiations produced by rock burst have directional characteristics.The energy radiation characteristics of the 22 rock bursts occurring on 79Z6 long-wall face are basically the same as theoretical results,that is,the ratio of S-wave energy of sensor 4 to 6 is about 1.5 and that of P-wave is smaller than 0.5.The consistency of the monitored characteristics of the energy radiation theoretically increases with the total energy increasing.
