摘　　要：在地下工程建设中,首次提出裂隙岩体高压涌水的关键孔注浆治理方法,并结合层次分析理论,研究关键孔的多因素层次优选方法。在龙固煤矿的辅2巷道高压涌水注浆治理的现场试验中,以地质分析和物理探测为指导,优化钻孔设计,以层次优选法对钻孔进行质量评价,筛选关键孔,参考连通试验结论对关键孔进行注浆设计,取得理想的治理效果,在类似工程治理中具有一定的推广价值。In the construction of underground engineering,the key-hole grouting method is first proposed in the treatment of high pressure water gushing problems of fractured rock mass.A key-hole optimization method of multilevel factors has been studied by analytic hierarchy process（AHP）.In practical engineering applications,grouting holes have been optimal designed by conclusions of geological analysis and physical exploration.Then the key-hole optimization method is used to select holes.The grouting parameters have been designed referencing conclusions of interconnection test.Finally,a good plugging effect has been achieved by grouting.The key-hole grouting method has good popularized value to similar projects.
