Abstract: In view of the problems of mining safety and others in the 90218 isolated island working face of Jinpushan Coal Industry Company, a rockburst hazard assessment was conducted based on the influence of geological factors and mining technical conditions. The research results indicate that the 90218 working face belongs to the non-rockburst hazard level, with an index of 0.24. Through static load analysis, the maximum value of static load stress of the working face is 22.78 MPa, which not reaches the critical stress level for triggering rock burst; After the superposition of dynamic load analysis and static load stress, there also not equipped with the occurrence possibility of rock burst; Multi-factor coupling method is adopted to comprehensively consider four main factors, including initial weighting, fault distribution, roadway intersection, and coal pillar size, the stress concentration areas of the working face are conducted to be finely divided, 2 areas of strong stress concentration, 7 areas of moderate stress concentration, and 2 areas of general stress concentration are identified. Reinforcement and other measures are adopted in the stress concentration areas, and multi-directional monitoring is conducted. The results indicate that the roof subsidence amount is reduced from 150 mm to 30 mm, with a reduction reaches 80%. During the whole mining process, there has no occurrence of rock burst, which effectively ensures the safe stoping of the working face.
