为确保采面回采安全，针对 32107 工作面瞬变电磁探测确定的底板异常区，布置 9 个探测钻孔对异常区进行探测及验证。钻探发现瞬变电磁确定的 3 个异常区均有一定的导水性。根据探测钻孔涌水情况进行统计并进行注浆实现底板导水裂隙封堵。底板注浆加固后，底板承压水突水系数最大为 0.0367MPa/m，采面后续回采过程中基本不会出现底板突水问题；同时在采面回采过程中通过在运输巷低洼处布置临时水仓以及排水泵，可将采面积水及时排出，确保采面回采安全。“,”in order to ensure the safety of mining face, nine detection boreholes are arranged to detect and verify the abnormal area of floor determined by transient electromagnetic detection in 32107 working face. Drilling found that the three abnormal areas determined by TEM have certain water conductivity. According to the detection of borehole water inrush statistics and grouting, to achieve the sealing of water flowing cracks in the floor. After floor grouting reinforcement, the maximum water inrush coefficient of floor confined water is 0.0367 MPa / m, and there is no floor water inrush problem in the subsequent mining process；At the same time, in the process of mining, the temporary water storage and drainage pump are arranged in the low-lying part of the transportation roadway to discharge the water in time and ensure the safety of mining.
