Abstract: Rockbursts are an extremely common geological hazard in engineering construction. The predicting and controlling rockbursts is crucial during the construction of underground mines, hydropower caverns, and transportation tunnels. This paper aims to review the key scientific problems of how to accurately predict rockbursts proneness before investigation or excavation of deep engineering rocks. Firstly, the criterion and prediction of rockburst are comprehensively analyzed from the existing research and development on the dynamics mechanism. The nonlinear law of energy accumulation, dissipation and release is discussed in the process of rockburst occurrence. The importance of the evolution of rock-cutting properties for rockburst prediction is emphasized under different high geo-stress conditions and different rockburst propensity levels. The previous understanding of the rockburst mechanism is supplemented by an in-depth discussion of the nonlinear energy dissipation law during rockburst, which provides new theoretical support for the identification of rockburst precursors and the judgment of the possibility of occurrence. Through the establishment of field-measurable rockburst propensity evaluation indexes and prediction models, the safety of deep engineering construction will be significantly improved.
