Abstract The basis of rock burst prevention is the identification of burst tendency. So it is very important that the identified indices are concise and rational. Based on the current analysis of burst energy indices，the time effect of both molding energy release and effectively utilized elastic energy release before coal rock peak was taken into an overall consideration. And a calculating model was set up to calculate the release speed of effectively utilized elastic energy. Also，based on the AE characteristic indices and molding energy release before the presentation of peak of recycled and unloading load，by using TYJ–500KN to control electro-hydraulic servo rock shear rheology test system recycled loading AE experiment for coal，the Section Function Calculation Formula was combined. The burst energy indexes identification experiment was carried out to confirm the reliability of the presented formula. The result shows that there is only 5.27% difference between the presentation of peak value unloading and the presentation of AE characters indices，and the two presentations prove each other. The release speed of effective elastic energy is in positive correlation with burst energy index，the uniaxial compression strength，and the effective elastic energy，but in negative correlation with time. Therefore，it is rational to identify the burst tendency by the effective elastic energy release speed.

Key words： mining engineering impact energy index plastic deformation energy effective elastic energy AE characteristic parameters
