摘　　要：根据石圪台煤矿开采的实际条件,运用FLAC3D数值模拟软件,建立了在过上煤层遗留煤柱中的应力场及覆岩运移规律模型。模拟了石圪台煤矿31201工作面在过2-2煤遗留煤柱时的矿压显现规律,分析了出煤柱时的失稳机理,为31201工作面安全生产提供理论依据。According to the actual conditions of mining in Shigetai coal mine, by means of FLAC3 D numerical simulation software,the stress field and the law of the overlying strata movement in the coal pillar of coal seam in coal seam are established. Simulation of Shigetai coal mine 31201 working face2-2coal by coal pillar when the behavior law of mine pressure in. The mechanism of instability of coal pillar is analyzed, which provides a theoretical basis for safety production at 31201 working face.
