Information de la recherche : Rockburst is a type of brittle rock failure occurring in deep underground excavations in an unstable and violent manner which could cause devastating consequences to the mine equipment and the site staff. To tackle this engineering problem, the rockburst failure mechanisms should be understood quite well. This project focuses on the metamorphic rock and aims to tackle the rockburst by precisely anticipating the rockburst occurrence using different approaches including the statistical, empirical, and numerical methods. For having a realistic prediction of rockburst, two key parameters (the geomechanical properties of metamorphic rocks and the state of in-situ stress) must be estimated. These findings will be applied to develop the most appropriate rockburst anticipation criteria based on empirical indices with a special focus on the nature of metamorphic rocks at the Westwood Mine.
