Abstract: The rock burst often happens in the procedure of deep mining in the metal mine.Studies on the reasons for the rock burst mainly focus on the high in-situ stress field with some limitations.In this study,the energy index and the stress index of shock hazard were introduced with consideration of rock properties and the state of the rock,enriching the parameters of studying rock burst.With the use of FLAC3D numerical simulation method,the problem of rock burst in deep mining in Linglong gold mine was simulated.Then,the risk for rock burst,the volume of the released energy and the scope of rock burst were primarily determined,which was in accordance with the actual situation after comparison.Therefore,this method can provide the basis for safe production and the following stoping in Linglong gold mine.

Key words: Energy index, Rockburst hazard, Deep mining, Numerical modeling
