The physical processes of rock burst are described from the viewpoint of crack propagation. The crack propagation is explained as the "intrinsic factor" of rockburst, the energy release during rockburst is considered as the "energy factor", and the fracture zone is considered as the "structural factors" for rockburst. The relationship between crack-related "three factors" and rock burst is established, in order to provide a theoretical basis to microseism and earth sound technology for predict rock burst.
