This paper focuses on a numerical analysis of the hard rock (ore) disintegration process. The bit moves into the ore and subsequently disintegrates it. The disintegration (i.e. fracture of the ore) is solved via deterministic approach (FEM) and probabilistic approach (FEM in combination with the Simulation-Based Reliability Assessment method, i.e. Monte Carlo simulations, stochastic inputs). The ore is disintegrated by deactivating the FE which satisfy the fracture condition. The results are compared with experiments. Application of the SBRA method in this area is a new and innovative trend. Finally, the probabilistic reliability assessment is proposed.
