摘　　要：在分析地质力学特征的基础上,采用数值模拟的方法,对潞阳瑞龙煤业15#下煤层150202下工作面两顺槽合理布置方式进行了研究。分析了不同布置方式的优缺点,确定采用外错布置;对不同煤柱尺寸时,煤柱垂直应力分布和巷道周边应力分布进行了分析,最终确定了合理煤柱尺寸。On the basis of analyzing the characteristics of geomechanics and using the method of numerical simulation,studies the reasonable layout of two roadways of the lower working face 150202 in the 15#closed distance coal seam of Luyang-ruilong coal mine.Analyzes the advantages and disadvantages of different layout,and decides to adopt the external dislocation arrangement;the vertical stress distribution of coal pillar and the stress distribution around roadway are analyzed for different coal pillar sizes,and the reasonable coal pillar sizes are finally determined.

关 键 词：布置方式 近距离煤层 数值模拟 应力分布
