Intense rockburst impacts in deep underground construction and their prevention

Canadian Geotechnical Journal, 2015
In the last few decades, in both mining and civil engineering projects, deeper excavations have been carried out than in the past. With this increase in depth, rocks may overstress and rock failures can occur during excavation. When competent rock strata are encountered under high stress conditions, these failures can vary from superficial spalling to
