The factors influencing the stability of surrounding rock of roadway such as rock structure characteristics, surrounding rock stress, support form has been briefly analyzed. Software of FLAC3D has been briefly introduced, and it has been used to build up numerical model of surrounding rock depending on the actual case, the distribution of vertical stress of roadway surrounding rock during the roadway extraction and recovery is obtained by calculation, the stress variation characteristics of surrounding rock in roadway has been revealed by analyzing the different vertical distribution in order to guide the production practice of surrounding rock support in deep roadway .
