Paper Title:
The Rockburst Experiment Usage of Similar Material and the Mechanism of the Energy Releasing
  Abstract

As 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 studied, whose peak velocity and acting time are analyzed. The results indicate that the formula for calculating peak velocity and the kinetic energy is proper and the kinetic energy is little portion of the recovery strain energy, most of which is dissipation in different ways; the unloading time at different positions apart from the free surface is nearly the same and more larger than the unloading wave’s disturbance time.
