Rockburst mechanism research and its control
International Journal of Mining Science and Technology, 2018 A new rockburst classification, innovative works in developing a “strainburst test machine” and an “impact-induced rockburst test machine” that can reproduce rockbursts in laboratory were researched. New concepts were proposed regarding the stress paths that take into account both the static and dynamic stresses analogous to that at excavation ...
