Based on the basic theory of ideal point method, considering the mechanism of rock burst, a model for predicting and classifying rockbursts is established. Five factors are selected as the evaluation indexes, including the ratio of the maximum main stress of the surrounding cave wall to uniaxial compressive strength of rock, the ratio of the maximum tangential stress of the surrounding cave wall to uniaxial compressive strength of rock, the ratio of compressive to tensile strength of rock, the elastic energ...
