摘　　要：根据某矿业公司201、203工作面复杂地质及生产技术条件,对2号煤层进行综合机械化开采,采用FLAC^(3D)对201、203工作面回采时采场围岩的应力分布及其变形破坏规律进行数值模拟研究,取201、203工作面不同阶段的数值计算模拟结果为研究对象,分析其位移场、应力场和塑性区分布特征,揭示不同阶段下工作面受采动影响的矿压显现规律。According to the complex geology and production technical conditions of the 201 and 203 working faces of a mining company,the No.2 coal seam is mined by the comprehensive machinery.FLAC3D is used to numerically simulate the stress distribution and the deformation and damage of the surrounding rock in the mining area during the mining of the 201 and 203 working faces.The numerical simulation results of the 201 and 203 working faces at different stages are taken as the research object.The distribution characteristics of the displacement field,stress field and plastic zone are analyzed,and the appearance rule of the mine pressure in different stages of the working face is revealed.
