【摘要】F8 water-conductive fault was disclosed during construction in taiyuan coal gasification Longquan Coal Mine North One air return roadway. According to reliable information ,F8 water-con-ductive fault has been broken No.4~ No.9 coal seam group and dow n to Ordovician. Based on the principle of safety first ,grouting and blocking on working face technology by combining with length and short holes was adopted according to actual situation .It is proved that the result of blocking water is better after practical excavation and the process of excavation is safe and smoothly through the wa-ter-conductive fault.%太原煤气化龙泉煤矿北一回风大巷施工过程中揭露F8导水断层，据可靠资料F8导水断层错断4～9号煤层组并且断至奥灰，本着安全第一的施工原则，结合实际情况采用长短孔相结合的工作面注浆工艺封堵涌水，后经实际开挖掘进，涌水封堵效果较好，安全顺利通过此导水断层。 【总页数】3页(105-107)
