基于FLAC^(3D)的深部巷道围岩变形数值模拟

Numerical Simulation on Deep Laneway Surrounding Rock Deformation based on FLAC^(3D)

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 FLAC^3D with theory directive function at a certain degree, it could be ob- served from analysis result that spray anchor note support could control surrounding rock deformation ef- fectively, 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.
