| Abstract: | This paper, with the aid of the finite element method, carries out a stability analysis about the height of the construction zone in a vertical shaft's combined operation, finds out the regularity of stress distribution in surrounded rock mass, and therefore decides on the different depths of the shaft as well as the heights of the construction zone under different rock stratum conditions. Finally, the paper suggests an increase in the present height of the construction zone in order to increase the speed of the shaft construction. |
