This paper presents numerical simulation for predicting fracture and failure growth of geomaterial using smoothed particle hydrodynamics (SPH). The first example deals with slope stability analysis of a chromite mine having friable chromite as ore body. The ultimate pit may reach upto 144 m below the surface having an ultimate pit angle 30° for 19 benches. It is required to forecast the stability of the ultimate pit slope for the given materials and pit geometry. The paper analyzes the stability of this slope considering Drucker-Prager rock mass medium in SPH procedure. The second example comprises of fracture growth of a circular rock specimen under diametrically opposite concentrated angle loads. In order to determine the plastic regime of the specimen for a given tensile strength, Rankine maximum tensile failure criterion has been implemented in the SPH framework.
