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