摘　　要：煤矿采区地质存在水量高、压力大等特点时,采矿过程中极易出现突水事故.一般涉及到特殊水文地质条件,会采取动水注浆堵水工程对含水层进行治理.本文主要分析定向分支钻孔在特大动水注浆堵水工程中的应用,结合具体案例,分析定向分支钻孔的技术要点和应用方案,提高特大动水注浆堵水工程施工有效性,确保煤矿生产安全.When the geological conditions of coal mining areas are characterized by high water volume and high pressure, water inrush accidents are highly prone to occur in the mining process. Generally, it involves special hydrogeological conditions, and the aquifer will be treated by the hydrodynamic grouting and water blocking project. This paper mainly analyzes the application of directional branch hole in the special hydrodynamic grouting and water blocking project. Combining with specific cases, it analyzes the technical points and application schemes of directional branch hole, and improves the construction efficiency of the special hydrodynamic grouting and water blocking project to ensure the coal mine production safety.
