摘　　要：通过对思山岭铁矿1#回风井工程勘察报告及工作面预注浆钻孔施工情况综合分析,选取合理的注浆参数及注浆材料对含水层进行超前注浆堵水,取得了良好的效果。工作面预注浆改善了井筒施工条件,加快了施工进度,同时也确保了施工的质量与安全,对相似水文地质条件的竖井开挖作业具有很好的参考价值。After analyzing the pre-grouting drill holes and studying the geotechnical survey report,proper grouting parameters and materials were determined,and pre-grouting was carried out against the aquifer to prevent water inflow,with satisfactory results achieved.The face pre-grouting operation has ameliorated the working condition in the shaft,accelerated work progress,and ensured construction quality and safety,the practice sets a good example for shaft development under similar hydrogeological conditions.

关 键 词：工作面预注浆 防治水 止浆垫 注浆压力
