... simulation adopts the strength reduction method to evaluate the factor of safety (FOS). The baseline simulation results show a FOS of 1.94, which indicates no shear failure on the open pit mine slope. We also investigate the impact of rock mass geomechanical parameters. The proposed workflow permits us...

.... For remote coordinates, error values are less than one percent; for locations too close to the cavity, with a finer mesh, error values are reduced to one percent with the same simple integration scheme. Additionally, for such simulation, semi-discontinuous elements result in higher error values even...

... ABSTRACT: In conventional continuum numerical models, rock is typically simulated as a homogeneous material. However, these models fail to capture pre-peak tensile damage in hard rocks under compressive loading. The Discrete Fracture Network (DFN) is widely used to generate various types...
