摘　　要：为科学确定煤矿冲击地压的影响因素及其影响程度,进而有针对性的研究煤矿冲击地压防治措施,采用事故树(FTA)分析法定性分析冲击地压影响因素,运用布尔代数法计算各因素的影响程度,并将冲击地压39项影响因素划分为3个等级,依此提出弱化煤岩冲击危险性,预评价、综合监测与动态防治,加强管理与开采优化三级冲击地压防治措施,实践证明:所提出的冲击地压防治措施效果良好。To scientifically determine the factors and influence degree of rock burst in coal mine, and study rock burst prevention and control measures of coal mine, fault tree analysis was applied to qualitatively analyze the influencing factors of rock burst, and Boolean algebra method was applied to calculate the influence degree of each factor. The 39 rock burst influence factors were divided into 3 grades, according to which a 3 level rock burst prevention and control scheme was proposed, comprising burst risk weakening, pre - assessment, comprehensive monitoring and dynamic control, management strengthening and mining optimization. The effect was verified in practice.
