Abstract: The numerical simulation on the actual mining sequence of ore-body is made by FLAC3D program to analyze the regional variation of the surrounding rock stress,deformation and plasticity caused by the mining at the upper stage,thus obtaining its regional variation rule.The paper provides a theoretical basis for the roadway stability control.

Key words: Deep exploitation, Tunnel deformation, Stress, Influence
