Abstract Rockburst is a common engineering-geological problem in deep underground engineering. In-situ stress measurement is an important premise for prediction of rockburst. According to the requirement of deep measurement and burying condition of rockmass in Sanshandao gold mine，overcoring technique is improved and in-situ measurement is carried out in deep mining area. Rock with capacity of storing strong strain energy and stress environment to cause high energy accumulation，as two necessary conditions for rockburst，are proposed. Based on the results of in-situ stress measurement and rock mechanical test，qualitative analysis of rockburst prediction is accomplished using the multiple criteria. The distribution and variation law of rockmass energy accumulation caused by deep mining are revealed by FLAC3D simulation. With the help of seismology method，location and intensity of rockburst during future mining process in Sanshandao gold mine are predicted. The study results provide a new approach for rockburst prediction in deep underground engineering.
