摘　　要：以云冈矿极近距离采空区下81005工作面开采为工程背景,采用理论分析、数值模拟的方法对比分析了下煤层不同布置方式下的煤柱应力与塑性区分布规律,得到了下煤层回采巷道布置与煤柱宽度的对应关系。研究结果为云冈矿81005工作面安全高效开采提供了指导,同时为相似条件下煤层群开采提供了借鉴。81005 working face of Yungang Mine was taken as example,the method of theoretical analysis,numerical simulation were adopted to analyze the coal pillar under different arrangement of the stress and the plastic zone distribution,the arrangement and the width of coal pillar under coal seam mining.The results provided guidance for the safe and efficient mining of the 81005 working face of Yungang mine,and also provided a reference for the mining of coal seams under similar conditions.
