Abstract

This thesis report presents a concept methodology to quantify the energy release associated with strain bursting in underground excavations based on the size of the failed zone and the elastic strain energy stored in the rock mass prior to failure. A strain burst implies potential harm to people and machinery and may lead to economic loss. An increased understanding of the amount of released energy rock support systems are subjected to allows for more convenient excavation design and risk mitigation.
