ABSTRACT: Deep mines and underground operations with a high extraction ratio are sensitive to ground stresses. Increasing stresses in a mining area can cause the failure of rock masses around openings and convergence of rock towards the exposed surfaces of excavations. Under a combination of circumstances such as the presence of strong and brittle rock and high stresses, it is possible for the rock mass to fail violently thus causing a rockburst.
