摘　　要：钱营孜煤矿副井立井已进行过多次注浆治理,但其涌水量仍高达10 m3/h。针对目前井壁可注性差,如再进行注浆将面临注浆压力高、难度大等问题,提出了采用改进型化学浆液注浆防水堵漏的施工方案。改进型化学浆液为固砂溶胶,该浆液由十余种化学材料配制而成。在系统分析了井筒水文地质工程地质条件后提出了适宜的施工方案。在方案实施中不断进行施工参数动态优化。最终实现注浆后涌水量仅为0.32 m3/h,堵水率高达97%。The auxiliary shaft of Qianyingzi mine has been injected for six times to prevent leakage of water. However, the total water inflow is still up to 10 ma/h. The transformeod chemical slurry was proposed to solve the leakage of water at the poor injection condition and big difficulty. The transformed chemical slurry is composed of several chemical mate- rials for solidifying sand. A suitable injection plan was proposed based on systematic analysis for geological and hydro- geological conditions of the shaft. Construction parameters were dynamically optimized during construction. And the total water inflow decreased to 0.32 m3/h after injection. The water blocking rate was 97%.
