Taking Yanbei Coal Mine of Huating mining area as background,precursory characteristics of acoustic emission and pressure for rock burst events in the course of mining were analyzed.The results show that acoustic emission and pressure in rock body of rock burst “source” present some related change law before rock burst,which exhibits obvious precursory characteristics and intercoupling model.“Pressor quiet and depressurizing active”model,it means that when the overall trend of pressure variation increases,acoustic emission goes into quiet period,conversely,when it decreases,the acoustic emission presents active.“Pressor and depressurizing quiet” model,namely,no matter the pressure goes up or down,acoustic emission always keeps in the quiet period.This feature and model can be used as distinguish basis to predict rock burst events.
