Abstract: In view of sharply rising status of working face pressure risk that is caused by the mining depth increasing and roof caving insufficiently near gob side during the mining period of Huating Coal Mine, the main factors influencing ground pressure risk are critical layer movement and periodic breakage. According to this, the critical layer is determined and the source of breaking force influence on rock burst is analyzed. Moreover, the pressure relief measures are created, and the management system is further improved. Compared with the approximate conditions near the working face, the breakage degree of ground pressure appearance has significantly declined,which guarantees the safety of the actual mining.
