摘　　要：司家营南区第四系含水量丰富,基岩裂隙含水丰富,局部沟通联系导致断层破碎带含水量大,施工极易造成突水淹井。针对该地区井下排水系统施工过程中遇到大型断层破碎带,进行了设计施工优化,降低了破碎带注浆治水支护成本。Quaternary system of southern district and bedrock fissure of Sijiaying Iron Ore Mine contain rich water.Local interlinkage leads fault fracture zone to contain large quantity of water and construction will easily cause water inrush and shaft flooding.Due to the encounter with large fault fracture zone during construction of drainage system under the shaft,construction design is optimized and grouting,water prevention and supporting cost for the fracture zone is reduced.

关 键 词：井建工程 注浆治水 安全施工
