Abstract: Dahongshan iron mine is oversize and deep-buried deposit，and a technical problem that must be faced in deep mining is rockburst.To evaluate the intensity of rockburst proneness，indoor rockburst pronenss experiments of five kinds of rock samples from deep mine are recorded，and acoustic emission is used to control the unloading point near to peak strength of rock；According to the ground stress measured in field and result of three-dimensional finite element numerical analog，maximum primary stress in deep mine and tangential stress values after tunnel excavation are obtained.Five judging methods of maximum primary stress criterion，tangential stress criterion，strength brittleness coefficient method，deformation brittleness coefficient method and elastic strain energy storage index method are used to make an estimation of one index about rockburst proneness，and rockburst proneness intensity of rocks in Dahongshan iron mine is obtained；Then，the method of fuzzy mathematics is used to make an integrated evaluation.The result shows that there is medium and strong rockburst proneness of main rocks in deep mining.At last，distribution map of rockburst proneness in typical level is plotted according to the evaluation result，which provides reference for mining and rockburst control in deep mining.
