Abstract
Taking MuGua mine geological and hydrogeological conditions as the basis in this paper, by FLAC3D numerical simulation software, the overburden failure law were studied during mining lower coal seam, the overburden failure height of near distance coal seam are calculated using the theoretical formula. According to the failure height of overlying rock developmental, the roof containing water inlfuence on the lower coal seam mining were analyzed, and to the corresponding measures for prevention and control water were developed, to, which has important practical signiifcance for the mine safety.关键词
