摘　　要：结合回坡底煤矿东区10#和11#近距离煤层开采地质条件,分析了10#煤层开采对下位11#煤层的影响,运用FLAC3D软件分析比较了下位煤层回采巷道外错式布置、重叠式布置、内错式布置方式的应力分布和塑性区情况。模拟结果和现场应用观测结果表明,采用重叠式布置方式是合理的,技术上可行。Combined with the close coal seams mining geological condition of No.10 and No.11 coal seams in Huipodi coal mine,analyze the floor damage after the No.10 coal seam mined.By FLAC3 D software the stress distribution and plastic zone in different layouts such as inner stagger layout,overlapping layout and lateral layout were simulated.The simulate result and the the engineering practices show that the overlapping layout is practical.

关 键 词：近距离煤层 采空区下 FLAC3D 回采巷道布置 重叠式布置
