Discrete element method based on spherical and cylindrical particles is widely recognized as a suitable tool to model geomaterials, advantages of this method are clearly seen in modelling problems characterized with strong discontinuities like rock fracturing during excavation. The discrete element model assumes that material can be represented by an assembly of rigid particles interacting among themselves. The overall behaviour of the system is determined by the cohesive/frictional contact laws. The contact law can be seen as the formulation of the material model on the microscopic level. Cohesive bonds can be broken, which allows us to simulate fracture of material and its propagation.
