Abstract：The engineering background is construction of 1 500‐meter‐deep Auxiliary Shaft in Sishan‐ling Iron Ore ,an overview of the wall’s structure features. According to the conditions of the scene of the shaft wall rock stress and groundwater ,calculate the surrounding rock stress of wellbore wall after excavation by theory ,then judge the stability of borehole wall.On the basis of this ,analyzing the same excavation process of in‐situ stress conditions by FLAC3D ,concluding shaft wall rock and supporting structure after excavation of the size of the displacement and stress distribution and change rule ,for practical engineering guidance and provide a reference for similar projects.
