In this research paper, smoothed particle hydrodynamics (SPH) with Johnson Holmquist damage model is adopted for modelling of the blast-induced fractures in Barre granite rock. The permeability of the blast-induced rock is then obtained using the implemented finite volume method code in OpenFOAM. It is found that the calculated permeability depends on the direction of fluid flow and with higher value in radial direction than the axial one. This is mainly due to the higher and larger connected pore network in the radial direction. This research work shows that the adopted SPH method along with finite volume method code can be effectively combined to qualitatively and quantitatively predict the fractured network, to analyse geometry of the fractured network, and to calculate the permeability of blast-induced rock.
