摘　　要：采用FLAC^(3D) 模拟软件,对比研究使用全部垮落法和条带法处理采空区时上覆岩层的变形量和垂直应力。模拟结果表明:条带法能有效地限制覆岩大幅度变形,控制地表下沉,尤其对"三下"下采煤有重大的作用;另外,条带法相比直接垮落法能有效降低空区垂直应力,从而减小工作面支架上的压力。Uses the FLAC3D simulation software, and compares overlying strata deformation and verticalstress mining method with strip method when they are studied of all collapse empty zone. Thesimulation results show that the strip method can effectively limit the deformation of overburden largeamplitude,and control the subsidence of surface, especially plays a major role in ＂three under＂ mining;in addition, compared with the caving method of dealing goals,strip mining can effectively reduce thevertical stress, thereby reducing the work on the support surface the pressure.
