摘要
根据研究区的实际地质和开采条件,运用FLAC3D数值模拟软件,建立煤层采动过程中应力场及覆岩运移规律的三维数值模型,模拟在1232(3)工作面和1242(1)工作面采动影响下,开采1242(3)工作面时矿山压力显现规律,为1242(3)工作面安全生产提供理论依据。
Based on actual geological and mining conditions in the study area,by means of FLAC3Dnumerical simulation software,this paper establishes the three dimensional numerical model of stress field and overlying strata movement laws during coal seam mining,so that it can simulate the strata behavior laws on mining 1242(3) working face under the mining influence of 1232(3) and 1242(1) working face,which provides a theoretical basis for safety production at 1242(3) working face.
