摘　　要：立井施工中,工作面预注浆是常用的治水方法。根据田陈煤矿北区新风井特殊的水文地质条件,多次采用膨胀式固孔注浆管进行工作面预注浆,不仅节省了混凝土止浆垫浇筑和拆除时间,而且由于固孔作业简便,易于操作,缩短了建井工期,技术经济效益明显。In the mine shaft construction ,a pre-grouting at the mine shaft sinking face is a conventional water treatment method. According to the special hydrogeological condition of a new mine ventilation shaft in the North Area of Tianchen Mine ,the expansion type borehole consolidation grouting tube was repeatedly applied to the pre-grouting at the mine shaft sinking face. Not only the concrete grou‐ting plug construction and dismantled time was saved ,but due to a simple borehole consolidation ope-ration and easy operation ,the mine shaft construction period was reduced and the technical and eco ‐nomic benefits were obvious.
