Abstract: In this paper, based on the engineering background of frequent rockburst events in the " square " area of a mine, the distribution characteristics of static load, dynamic and static load quantitative superposition abutment pressure of the working face are analyzed, and the rockburst mechanism of the special area with strong bursting liability roof is obtained : the goaf of the working face exerts static load on the side of the wide coal pillar, so that the coal and rock mass in the affected area reaches the critical state of rockburst ; under the influence of a large amount of elastic energy released by the breaking of strong bursting liability roof, rock burst disaster occurs in coal rock under the critical state of impact. The targeted prevention and control measures of rock burst are put forward for coal body and strong bursting liability roof. The large diameter pressure relief drilling and coal seam water injection pressure relief measures for coal seam construction , and the blasting pre-splitting measures for strong bursting liability roof construction ensure the safe production of working face. The research results can provide reference for the safe production of mines under similar conditions.
