    Inspection and Control Technology for Mine Water Conductive Fault Mining Under Pressure

    • Qipanjing Coal Mine, which mainly mines the 16# coal seam, is threatened by ordovician limestone water hazard. During the roadway excavation, DF1 and DF3 faults are founded. The average distance between 16# coal seam and ordovician limestone is about 38.72 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.
