Rock burst is a common geological disaster in the process of deep mining. The occurrence of rock burst is sudden, instantaneous and destructive. In order to predict the occurrence of rockburst, this paper calculates the elastic strain energy based on the uniaxial compressive strength test results, and identifies the rockburst tendency according to the maximum storage elastic strain energy index and the improved brittleness index. The results show that the rock burst tendency of core samples is either no rock burst tendency or no rock burst tendency. This method provides a scientific theoretical basis for predicting rockburst tendency from the perspective of energy index.
