Abstract: In order to predict and evaluate rock burst during mining period for Huxi Coal Mine 31202 working face, the influencing factors of dynamic and static load of mine pressure were analyzed. The stress field distribution of working face was simulated by FLAC^3D; the support stress of coal with the advancing of working face is analyzed emphatically and the factors of rock burst were analyzed and the regions of rock burst hazard were divided. Finally, schemes were proposed to prevent rock burst under different conditions of dynamic load and static load.
