摘　　要：在对柴里煤矿3_上906东不规则孤岛工作面冲击倾向性分析的基础上,得出了孤岛工作面及不规则区域的支承压力分布特征。通过煤层预注水卸压、大直径钻孔卸压等综合卸压技术对冲击地压危险区域进行了防治,并利用钻屑法进行监测并检验解危效果,最终降低了工作面采掘期间的冲击危险性,实现了孤岛工作面的安全生产。Based on the analysis of outburst proneness, the distribution characteristics of the support stress of the island working face 3up906E of Chaili coal mine and irregular zone are concluded. The rock burst in the dangerous zone is prevented by the comprehensive pressure relief technology such as flooding water to coal mine in advance, large-diameter drilling pressure relief. Reliving stress effects are detected and verified by the drilling bits method. In the end, the degree of impact danger of working face is decreased during the advancement. The safety production of island working face is realized.
