The application of Energy Analysis during the course of pressure bump generation

Abstract：The major factors of pressure bump generation are natural factors and mining factors. The classification of pressure bump is determined by the energy theory, and the energy release mechanism is explained from the viewpoint of the mechanics principle. To reduce energy accumulation of coal-rock mass, some reasonable methods have been put forward to prevent the occurrence of pressure bump. The conclusions have a directive function for the coal mines with pressure bump.
