Abstract:Rockburst is a difficult geological disaster in mine production, which seriously threatens the safety of personnel and equipment. To reasonably predict rockburst, the stress coefficient σθ/σc brittleness coefficient σc/σt, and the elastic energy index of Wet are selected as grading evaluation indexes. The weights of the indexes are determined by the combination of subjective and objective weights. The subjective weighting method is an expert scoring method, the objective weighting method is an entropy weighting method, the combination weighting method is used to adjust the subjectivity of weight determination through combination weighting, and the extension is comprehensive evaluation rockburst prediction model of combination weighting is established. The established model is applied to the project, and the predicted result is consistent with the actual situation, which is a model that can be applied to the project.
