摘要
为了研究相邻平行巷道围岩应力分布,应用ANSYS有限元软件,模拟不同开采深度,不同岩柱宽度时的巷道围岩应力分布特点,通过分析拱顶、拱基、墙中、墙底这些关键点的水平及垂直应力,概括总结影响相邻巷道稳定性主要应力因素,为煤矿安全、经济生产提供参考。
In order to study the distribution of numerical stress of surrounding rocks, with the ANSYS finite element software, simulates different mining depth, different rock pillar width of the roadway surrounding rock stress distribution characteristics. Through the analysis of the arch, chaptrel, wall and the horizontal and vertical stress at the bottom of the key points, this paper summarizes the main stress factors influencing adjacent tunnel stability, provides a reference for coal mine safety and economic production.
