摘　　要：本文在53_下01(南)胶顺沿空掘巷工作面环境的基础上,提出治理冲击地压的综合防治技术。制定以钻屑法为主,微震监测和应力在线监测相结合的监测方案,超前大直径钻孔卸压,煤体爆破卸压与顶板高压水预裂相结合的治理措施。观测结果表明,监测措施有效预测了高应力积聚区域的位置及强度,采取解危方案有效,预防了冲击地压给生产带来的安全隐患,对冲击地压防治具有重要的借鉴与指导意义。On the basis of the analysis of environment of roadway driving along the gob at53(01)down,a comprehensiveprevention and control technique for rock burst is put forward.A monitoring scheme based on drilling method,microseismicmonitoring and stress on-line monitoring is put forward,and the control measures of large diameter borehole pressure relief,coalblasting pressure relief and roof high pressure water pre cracking are combined.The observation results show that the monitoringmeasures effectively predict the position and strength of high accumulation area,taking the safety controlling scheme preventrockburst to produce,which is an important reference and guide for rockburst prevention.
