Paper presented at the ISRM 2nd International Conference on Rock Dynamics, May 18–19, 2016
Paper Number: ISRM-ROCDYN-2016-01
... system. In seismically active mines, this essential task is more difficult as high rates of deformation and dynamic loading are still comparatively infrequent events and the simulation of support and reinforcement for dynamic loading is more complex. Empirical methods of estimating excavation capacity...

Paper presented at the ISRM 2nd International Conference on Rock Dynamics, May 18–19, 2016
Paper Number: ISRM-ROCDYN-2016-40
... 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...

Paper Number: ISRM-ROCDYN-2016-36
... ABSTRACT: This work presents a new approach in simulation of rock blasting process by coupling the Finite Element Method (FEM) and the Smooth Particle Hydrodynamics (SPH) method. The rock is initially modelled with FEM whereas the explosive is modeled with SPH. Interaction is achieved...

Paper Number: ISRM-ROCDYN-2016-47
... ABSTRACT: A three dimensional (3D) Voronoi tessellations based on Distinct Element Method (DEM) is proposed for simulation of crack initiation and propagation in polycrystalline-based brittle rocks. Damage evolution equations for brittle rocks have been extensively studied in the past. However...

Paper Number: ISRM-ROCDYN-2016-53
.... In order to investigate fracture behaviour of sandy mudstone subjected to dynamic loading, both experiments and numerical simulations are performed at different impact velocities, respectively. Experiments are carried out with the Split Hopkinson Pressure Bar (SHPB), and numerical simulation is conducted...
