摘要
2006年曹窑东井27080工作面突然发生大型奥灰滞后突水,最大涌水量达到1 693m3/h,通过矿井水文地质条件分析,曹窑东井及相邻西部四矿大部分区域已处于"突水危险区"。为避免奥灰突水灾害再次发生,提出了"以防为主"的预防奥灰突水的技术手段和方法步骤,以探索深部煤炭开采的防治水工作。
A large Ordovician limestone lagged water bursting happened after 2006 No.27080 working face water bursting in the Caoyao East Coalmine, maximum outflow rate was 1693m^3/h. Through mine hydrogeological condition analysis, showing that most part of the Caoyao East Coalmine and adjacent western No.4 Coalmine have already situated in the ＂water bursting hazardous zone＂. To avoid another Ordovician limestone water bursting disaster, a ＂prevention first＂ technical means and methodic approaches have put forward to probe into water controlling works during deep part coal mining.
