Abstract: A modified energy criterion of the rock burst is proposed, by accounting for the brittleness index and the rock burst energy criteria comprehensively. The energy accumulation in the rock burst incubation process was tracked and analyzed quantitatively, and the intensity and the position of the rock burst in the excavation process of the underground engineering under the high stress were predicted reasonably based on the numerical simulations. The evolution of the rock burst incubation was explored. The rationality and effectiveness of the modified energy criterion were verified by comparing the original prediction index applied to the typical rock burst case.

Key words: Rock Burst, Energy, Tendentiousness Judgment
