摘　　要：棋盘井煤矿主采16#煤层,掘进期间遇DF1、DF3断层,受到煤层底板奥灰水突水威胁。井田范围内16#煤层与奥陶系灰岩的平均间距为38.72 m,最高带压1.9 MPa。以此为例,提出了断层探查、泄压引流及靶面帷幕注浆治理方案。通过探放水及治理工程的实施,确保了导水断层带的掘进安全。Qipanjing Coal Mine,which mainly mines the 16#coal seam,is threatened by ordovician limestone water hazard. During the roadway excavation,DF1 and DF3faults are founded. The average distance between 16#coal seam and ordovician limestone is about38. 72 m. After calculation,mining the 16#coal seam would be under 1. 9 MPa water pressure. Plans for faults detection,dewatering and target surface curtain grouting are presented and conducted to make sure that the roadways near fault zone are safely excavated.
