摘　　要：山西寿阳潞阳瑞龙煤业有限公司150103轨道顺槽位于井田中部,受南侧150102轨道顺槽及采空区影响,需确定合理的煤柱留设宽度。针对这一情况,本文通过理论计算与数值模拟相结合的方法,分析了不同煤柱宽度下巷道围岩的塑性区分布和应力环境,确定了最优的煤柱留设宽度为8 m。实践表明,该煤柱对巷道围岩变形起到了很好的控制作用,为研究类似条件下的煤柱留设提供了经验参考。Shanxi Shouyang Luyang Ruilong Coal Industry Co.,Ltd.150103 track crossheading is located in the middle of the mine field,affected by the 150102 track crossheading and goaf on the south side,it is necessary to determine the reasonable coal pillar width.In view of this situation,this paper analyzes the plastic zone distribution and stress environment of roadway surrounding rock under different coal pillar widths by combining theoretical calculation and numerical simulation,and determines that the optimal coal pillar width is 8 m.The practical production shows that the coal pillar has a good control effect on the deformation of roadway surrounding rock,which provides an empirical reference for the study of coal pillar retention under similar conditions.
