Abstract: Whit the further deep vertical shaft being excavated, the geological and mechanical conditions of vertical shaft become more complicated compared with those in shallow roadway.. The horizontal crustal stress is the main reason resulting in the surrounding rocks’ deformation and failure. Under the condition of different side pressure coefficient ? and horizontal stress ratio k, selecting the section shape of vertical shafts that have different axial ratio (b/a) to research the surrounding rock’s stress distribution and deformation features. The result shows that the equal stress axial ratio of deep vertical shaft surrounding rocks is different from that of deep buried elliptic roadway. The equal stress axial ratio of deep vertical shaft surrounding rocks is related to the horizontal stress ratio k. When side pressure coefficient and horizontal stress ratio are both constant, stress concentration areas of different shaft cross-section axial ratio mainly distribute in both ends of the x-axis of the shaft. The maximum deformation is in both ends of the y-axis. From the stress distribution and deformation analysis, under the same conditions, when using circular section to excavate the shaft, the disturbance of the surrounding rock affects the minimum. On the basis of analyzing shaft wall rock stress and deformation characteristics, the concept of shaft surrounding rocks double shell compound support was proposed, and its reinforcement mechanism was analyzed.
