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 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: FLAC^3D, Spray anchor note support, Numerical simulation
