摘要: 应用FLAC3D对东荣二矿深部巷道围岩变形进行数值模拟,在一定程度上起到理论指导作用,从分析结果可以看出喷锚注支护可以有效地控制围岩变形,改善巷道围岩应力分布,减小巷道位移量,提高围岩强度和自承能力,支护结构长期稳定,能够很好地解决深部破碎巷道围岩变形控制问题。

Abstract: Numerical simulation was done on deep laneway surrounding rock deformation of Dongrong No.2 mine by using FLAC3D with theory directive function at a certain degree, it could be observed from analysis result that spray anchor note support could control surrounding rock deformation effectively, improve laneway surrounding rock stress distribution, reduce displacement amount of laneway, enhance strength of surrounding rock and self-bearing ability, support structure long-time stable could solve deep crush roadway surrounding rock deformation controlling problem well.

Key words: FLAC3D, Spray anchor note support, Numerical simulation
