N2  - Aiming at the rock burst disaster of No.6303 working face in Jisan coal mine of Yanzhou coal group co. ltd, the state and reason of rock burst were analyzed. Based on the geological conditions and numerical simulation, the hard rock roof blasting method and blasting parameters were proposed to prevent rock burst. The blasting effect was checking using sight instrument, electromagnetic emission (EME) technique and drilling sludge methods. The results show that by this blasting method, the hard rock roof above the coal seam is destroyed and the elastic energy in rock roof was mostly released. The rock burst danger is reduced to guarantee the safety of working face. The practical application proves that this technique can effectively prevent the rock burst caused by hard rock roof.<p />
