| Abstract: | In order to effectively prevent rock burst in ZF2803 working face,this paper adopts the multi factor coupling analysis method to study the single influence area and superposition effect of seven factors,such as initial weighting,square,coal pillar,fault,abutment pressure of adjacent goaf,coal seam thickness change and roadway bottom coal,and determines seven risk areas:four medium impact risk areas and three strong impact risk areas,and gives the corresponding pre pressure relief measures of large boreholes in coal seam and floor,and good prevention and control effect is obtained in industrial application. |

| Keywords: | rock burst multi-factor coupling large boreholes pre-releasing pressure |
