Numerical Analysis of Induced Mechanism of Rockbursts in Tunnels
58th U.S. Rock Mechanics/Geomechanics SymposiumABSTRACT: Rockburst is a sudden and violent failure characterized by the breaking up and expulsion of rock from its surroundings. Tunnel rockbursts pose a significant threat to the safety of excavation operations, leading to property damage and tunneler casualties.

A Mechanism for High Wall-rock Velocities in Rockbursts
pure and applied geophysics, 1997Considerable evidence has been reported for wall-rock velocities during rockbursts in deep gold mines that are substantially greater than ground velocities associated with the primary seismic events. Whereas varied evidence suggests that slip across a fault at the source of an event generates nearby particle velocities of, at most, several m/s ...

The Rockburst Experiment Usage of Similar Material and the Mechanism of the Energy Releasing
Advanced Materials Research, 2011As one of the geological disasters, rockburst is often generated in underground engineering under excavation unloading conditions in high geostress areas. Taking advantage of the simulation test especially for the rock mass under high hydrostatic stress, the dynamic failure rockburst style resulted from instantaneous unloading in one direction was ...

The induced mechanism of pillar rockbursts in deep hard rock mines
Proceedings of the International Conference on Deep and High Stress Mining, 2014Rockbursts remain one of the most serious and least understood problems in deep hard rock mines. This study is motivated by the pervasiveness of rockbursts all around the world. It is found that rockbursts are often induced by dynamic fluctuations, which are generated by mining excavations or other sources of vibrations, such as blasting in adjacent ...
