摘要
以山西沁水煤田寺河矿区为工程背景,依托水文地质补充勘探数据,从研究奥陶系峰峰组顶部岩层的阻水能力出发,论证了矿区内相对隔水层的存在性,最后通过流固耦合数值模拟研究证明了相对隔水层存在时,下组煤带压开采条件得到明显改善。因此研究下组煤带压开采条件的关键因素之一是确定奥陶系顶部岩组本身是否具备较好的阻水能力。
Taking Sihe Mine for background,according to additional hydrogeological exploration,the water resistance properties study about Fengfeng Group was done to prove the existence of relative aquifuge.At last,numerical simulation by FLAC3D was done when relative aquifuge exists to prove that the mining condition in deep part resource with water pressure gets clear improvement.So one of the key factors to do research in this condition is to find out whether the top part of Ordovician gets enough water resistance.
