Abstract: This paper focuses on a numerical analysis of the hard rock (ore) disintegration process. The bit moves into the ore (i.e. mechanical contact with friction) and subsequently disintegrates it. The disintegration (i.e. stress-strain relationship, reaction forces and fracture of the ore etc.) is solved via the FEM in combination with SBRA Method. The ore is disintegrated by deactivating the finite elements which satisfy the fracture condition. Material of the ore is given by bounded histograms. The results are compared with experiments. Application of the SBRA method in this area is a new and innovative trend.
