Simulation-Optimization Investigate Into Resist Dynamical Pressure Shaft Wall

Based on the construction of a shaft wall in mining influence area, the different structure types of the shaft wall are numerical simulated by FLAC^3D numerical simulation soft. The structure types, includes pure concrete, reinforced concrete, complex shaft wall with added gasket to outside shaft wall and complex shaft wall with added stow-wood to inside shaft wall, are compared with each other. And the influences of stow-woods in different positions and its stiffness are analyzed. The simulation indicates that added stow-wood to inside of shaft wall is better and gasket thickness positions(stiffness) have little effect to shaft wall loaded.
