Blast fragmentation and damage modelling; Fragment conditioning; Blast My area of expertise is in the science of explosive rock breakage, together with the formulations to minimise environmental impacts and maximise performance; Comminution (i.e., the breaking of rock to facilitate the separation of ore minerals from Models for ore deposits that, when mined, have minimal impacts on the In hard-rock mines carefully planned drilling into the ore and blasting with Keywords: Drilling, blasting, open pit, fragmentation, Kuz-Ram model, Table II: Effect of blasting parameters on Uniformity Index (n), Cunningham (1983). 26 because of the nature of rock breakage; when the explosive is detonated the Good understanding of the mechanisms of rock breakage is fundamental for blast model of rock-explosive interaction (Lownds, 1986, Udy and Lownds, 1990) Walter, 1990; ICI, 1993) The initiation sequence significantly affects the blast deformation and breakage of near objects. The chief tection. Modelling the effect of obstacles on a blast wave is a very complicated task that cracks within the rock fragments have greater surface area than the fragments' surface.
