No.4-1051 Face of Zhengli Coal Industry was under pressure. In order to effectively prevent water outburst accidents caused by exposing hidden faults, collapse columns and other water conducting structures in the working face, advanced seismic detection was carried out when the air intake roadway was excavated to a full-scale of 133 m. A total of three abnormal reflection interfaces were found. Finally, through drilling verification, faults were developed in these three locations and different degrees of water outburst occurred at the borehole exposure. The maximum water inflow occurred at the abnormal position of R3, and the water inflow reached 36 m3/h. Practice showed that the seismic method was scientific and effective in detecting abnormal water conducting structures including faults and collapse columns, which provided experience for geological structures detection of the mine.
