摘　　要：为了解厚煤层采准巷道布置形式对围岩稳定性的影响,文章通过数值模拟,分析了巷道沿顶掘进、布置在煤层中间和沿底掘进三种不同布置形式下围岩的变形情况,并监测巷道围岩的变形数据。研究发现,巷道沿底掘进时,整体变形较为均匀,顶板、帮部和底板位移梯度均较小,有利于增强围岩的稳定性。In order to understand the influence of developing roadway layout on the stability of surrounding rock in thick coal seam,this paper analyzes the deformation of surrounding rock under three different layout forms of roadway excavation along the roof,arrangement in the middle of coal seam and excavation along the bottom through numerical simulation,and monitors the deformation data of roadway surrounding rock.It is found that when the roadway is excavated along the bottom,the overall deformation is relatively uniform,and the displacement gradients of the roof,side and floor are small,which is conducive to enhancing the stability of the surrounding rock.
