摘要： 以矿井孤岛工作面5110 运输大巷为研究背景，通过FLAC3D 数值模拟软件分析了巷道垂直应力变化规律，利
用数值模拟中的支护参数进行工程应用。工程应用结果显示，加强支护方案在控制煤层离层量、煤层顶板夹层离层量、
巷道两帮位移量和煤层顶板位移量方面有良好的效果，保证了巷道断面的完整性，可以在矿井推广应用。

Abstract: Taking 5110 transportation main roadway in the isolated working face of the mine as the research background, this
paper analyzed the vertical stress change law of the roadway is by FLAC3D numerical simulation software. And the support
parameters in the numerical simulation were used for engineering application. The engineering application results show that the
strengthening support plan was of good application effects in controlling the amount of separation of the coal seam, the amount of
separation of the interlayer of the coal seam roof, the displacement of the two sides of the roadway and the displacement of the
coal roof, which can ensure the integrity of the roadway section, and can be promoted and applied in the mine.

Key words: isolated island working face; FLAC3D numerical simulation; strengthening support plan
