文章根据马路坪矿深部软岩巷道表面位移的实测结果,分析了巷道围岩变形主要特征.通过数值模拟计算,探讨了巷道围岩破碎区、塑性区范围和应力位移分布规律,为巷道合理支护形式的选择提供了理论依据.

Based on the measured results of the displacement of deep soft rock roadway in MaLuPing mine, the deformation characteristic of the surrounding rock is analyzed. Through numerical simulation with FLAC3D, the ranges of the fragmentation area and the plastic area, the distribution of stresses and strains of the surrounding rock around roadway are discussed to put forward theoretica...
