... ABSTRACT: The P-wave propagation through fractured rock mass is simulated using UDEC with a cohesive fracture model. A series of laboratory tests from literature on P-wave propagation through rock mass containing single fracture and two parallel fractures are introduced and the numerical model...

... ABSTRACT: Over a number of years, the Fracture and Shock physics group has engaged with the blast mining industry to investigate the physics of geological materials. This has encompassed a wide variety of materials including a number of sandstones, gneiss, schist, granite and iron ore. Efforts...

... ABSTRACT: The Representative Elementary Volume (REV) of fractured rock masses plays an important role on determining the rock mechanical characteristics. Firstly studying the general methodology of rock REV are summarized, and the modelling of Discrete Fracture Networks (DFN) is proposed...

... ABSTRACT: Fractures with weakly and strongly correlated aperture distributions were used to explore a fundamental scaling relationship between fracture stiffness and fluid flow in a fracture. Computational models were used to analyze fluid flow through a fracture undergoing deformation...
