摘　　要：田兴铁矿大贾庄进风井-450 m沿脉巷穿过F10断层破碎带,探孔长探40 m,涌水量达到75 m3/h,且钻进过程卡钻严重。为防止掘进过程中出现大涌水,采用工作面预注浆技术,在巷道周边形成帷幕,封堵涌水并加固围岩。试掘后工作面顶板出现冒落,采用超前管棚、钢拱架、锚喷网3种方式联合支护,取得了较好的效果,顺利通过断层破碎带。The -450 m strike drift of Dajiazhuang shaft in Tianxin iron mine gets through the F10 fault fracture zone,the drilling hole depth is 40 m,the quantity of water gushing is 75 m3 /h,the sticking phenomenon is serious in the process of drilling.In order to deal with the water gushing in the process of tunneling,the working face pre-grouting technology is adopted to form the curtain around the roadway so as to seal the water gushing and reinforce the surrounding rock.The phenomenon of roof caving of work-ing face is appeared after pre-tunneling,the combined supporting scheme based on the advance tubing shield,steel arch shelf and rock bolt-net-shotcreting is adopted to get through the fault fracture zone suc-cessfully,and the good effect is obtained.
