Simulation of Large Span Chamber Stability: Hoek Brown and Point Safety Factor Optimization

The design of rock stability analysis and initial support is critical in the construction of super large span (SLS) chambers. Firstly, the point safety factor under the unloading stress path is derived and established using the instantaneous linearization method, based on the nonlinear Hoek Brown (H...
