摘　　要：分析榆树泉煤矿+1625 m泄水巷水文地质情况,得出顶板赋存大量裂隙、在采动影响下裂隙存在贯通形成导水通道危险的结论。为预防顶板突水,提出采用注浆手段加固顶板的方法,研究了泄水巷掘进前方布置施工定向注浆钻孔的技术,现场应用较好,保证了矿井的安全高效生产。Based on the analysis of the hydrogeological conditions of the+1625 m drainage roadway in Yushuquan Coal Mine,it is concluded that there are a large number offissures in the roof,and there is a danger of thefissures connecting to form a water diversion passage under the influence of mining.In order to prevent water inrush from the roof,the method of reinforcing the roof by grouting is proposed,and the technology of arranging directional grouting drilling holes in front of the drainage roadway excavation is studied.Thefield application is good,ensuring the safe and efficient production of the mine.
