Tunnel rockbursts induced by dynamic disturbances: mechanism and mitigation

IOP Conference Series: Earth and Environmental Science
Abstract Rockbursts are characterized by violent rock fractures and pose a significant threat to hard-rock tunnels, potentially resulting in casualties and damage to excavation spaces. Globally recognized as one of the least understood and most feared challenges in underground excavations, rockbursts are often triggered by dynamic ...
