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 em

This paper investigates fragmentation in an aggregate quarry in the light of the fragmentation-energy fan concept. Six blasts were monitored, located one behind the other in the same quarry area. The rock structure was blocky, the water level and the

The general ranges of validity of some distribution functions are assessed from their behaviour with 119 sets of fragmentation data from bench blasting obtained by sieving. The emphasis is on determining the lower size/passing limit that the size-sca

Este trabajo analiza algunos métodos de medida de vibraciones producidas en voladuras. Se han ensayado dos geófonos triaxiales de diferente tipo, tamaño y masa en un excitador de vibraciones. Los sensores se han acoplado a una losa de granito usan
