Abstract:
There are two necessary conditions on rock burst to occur which are its strong ability of storing strain energy and the environment that gathered with high strain energy for surrounding rocks.The paper relies on the deep mining of Sanshandao gold mine as the research background,based on the indoor physical mechanical test in the room,and uses three judgement indices which are brittleness coefficient, linear elastic energy,and impact properties to do some qualitative analyses to rock burst's shock tendency of Sanshandao gold mine's deep mining;it calculates the elastic strain energy accumulation and the characteristics of distribution on the basis of FLAC
3D numerical simulation and the total energy within the scope which maximum linear elastic can be framed of surrounding rock in the stope;it does the quantitative prediction to earthquake magnitude of rock burst based on the theory of seismology.The research results has the important guiding significance to the design optimization of deep mining,the control of rock burst and ensure efficient safety mining.
