应用FLAC^3D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.
