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。
田興鐵礦大賈莊進風井－450 m 沿脈巷穿過 F10斷層破碎帶，探孔長探40 m，湧水量達到75 m3／h，且鑽進過程卡鑽嚴重。為防止掘進過程中齣現大湧水，採用工作麵預註漿技術，在巷道週邊形成帷幕，封堵湧水併加固圍巖。試掘後工作麵頂闆齣現冒落，採用超前管棚、鋼拱架、錨噴網3種方式聯閤支護，取得瞭較好的效果，順利通過斷層破碎帶。
전흥철광대가장진풍정－450 m 연맥항천과 F10단층파쇄대，탐공장탐40 m，용수량체도75 m3／h，차찬진과정잡찬엄중。위방지굴진과정중출현대용수，채용공작면예주장기술，재항도주변형성유막，봉도용수병가고위암。시굴후공작면정판출현모락，채용초전관붕、강공가、묘분망3충방식연합지호，취득료교호적효과，순리통과단층파쇄대。
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.
