Abstract Under the complex and water-rich geological conditions, aiming at the influence of the coupling of groundwater pressure and in-situ stress on the shaft stable state, the fluid-solid coupling numerical simulation was used to analyze the deformation of the wellbore and the evolution characteristics of the plastic zone of the surrounding rock behind the wall under the action of groundwater seepage. The results showed that there were obvious stress concentration areas at the bottom of the sand section and the bottom of the bedrock section of the Zhiluo Formation, and the maximum stress in the stress concentration area increased to about 9.69 MPa. The displacement of the sand section of the shaft did not change significantly, and the sinking amount of the shaft wall of the Zhiluo Formation tended to be stable, and the maximum displacement tended to 11 mm ; the development of the plastic zone of the surrounding rock behind the wall was not obvious, and only the outer wall of the wellbore was damaged. Therefore, the stress concentration of the return air shaft was within the safe range, and the shaft had no obvious deformation, and the shaft was in a stable state.

Key words： shaft instability water pressure fluid-solid coupling seepage
