摘要：
In order to develop economical and effective support technology suitable to chinese conditions, the deformation and fracture mechanism and control principle of deep rock roadway need to be studied. In this paper, the deformation fracture mechanism and the stability evolution of surrounding rock is analyzed under the complex geological condition of high underground stress, high head pressure and high temperature gradient(THM). And the control theory for stability of deep roadway is proposed: recovery and improvement of stress, strength enhancement, consolidation and restoration of fracture damage zone, transformation of peak stress and enhancement of loading bearing zone.
