摘要
司马矿1208运输顺槽掘进至560 m处位于1207采空区巷帮及出现渗水现象,导致巷帮煤体片帮严重,巷帮支护难度大。针对这一问题,决定对邻近1207采空区采取合理有效的探放水施工技术。对1207采空区采取探放水技术后,巷道在后期掘进过程中共计探放采空区积水量7455 m3,消除了采空区积水水害隐患,保证巷道后期安全快速掘进,取得了显著应用成效。
Sima Mine 1208 transportation roadway mining with 560 m,where the roadway with water phenomenon in 1207 goaf area,resulting in serious coal flakes on the roadway side and great difficulty in supporting.In response to this problem,it was decided to adopt reasonable and effective water exploration and release construction technology for the adjacent 1207 goaf area.After adopting the water exploration and release technology for 1207 mining area,a total of 7,455 m3 of water in the mining area was explored and released during the later mining process,which eliminated the hidden danger of water damage in the mining area and ensured the safe and rapid mining,with remarkable application results.
