摘　　要：近距离煤层上部煤层开采所形成的应力集中,影响下部煤层布置回采巷道。该文运用FLAC^(3D)数值模拟软件对煤柱内应力分布及传递规律进行数值模拟计算,得出煤柱的宽度对下方底板应力传递及分布规律的影响,对近距离煤层回采巷道布置方式与支护有一定的指导作用。The stress concentration formed by the upper coal seam mining in the close distance, will influence on the lower coal seam arrangement and extraction roadway. In this paper, the FLAC3D numerical simulation software is used to simulate the internal stress distribution and transfer law of coal pillar. Get the influencing range and the distribution law of the floor, which has certain guiding and supporting role To close distance coal seam mining arrangement.

关 键 词：FLAC3D模拟近距离煤层 煤柱 集中应力 回采巷道
