Review of published rockburst events and their contributing factors

Through a review of selected published case study data from around the world, in situ conditions that contribute to rockburst events have been identified. This review was carried out to assist research associated with developing numerical modelling techniques to reproduce rockbursting within a large-scale (mine models) for predictive purposes. Contributing factors identified through the case study review include unfavourable stress states, excavation geometry (size and orientation in relation to the principal stresses) and rate and direction of advance. Factors also incorporated unfavourable rock mass characteristics that included mineralogy, contrasts in geomechanical properties, and geological intensifiers (dykes, faults, etc.).
