Abstract
A smoothed particle hydrodynamics (SPH) model has been developed in LS-DYNA for the simulation of the movement of the rock burden. The model is validated with experimental full-scale quarry tests performed within the EU project SLIM. The explosive employed in the tests, an emulsion, has been modelled with the JWL equation of state. The rock was modelled with the RHT constitutive material model. The interaction between explosive and rock is modelled with a node-to-node penalty-based contact. The fracture in the burden and the movement of the rock were monitored by high-speed video recording, with which the initial velocity of the rock face, and the time from the detonation to the onset of the face movement were obtained. These data have been used to calibrate the SPH model. A thorough comparison of the results of tests and simulation are shown.
