Evaluation Model of Rockburst Emergency Management Capability Based on PPRR Theory
In view of the complexity,fuzziness and uncertainty of the evaluation of rockburst emergency management ability in deep mines,a comprehensive evaluation model based on improved extension cloud was established to further improve the reliability of the evaluation.Firstly,according to the PPRR(Prevention,Preparation,Response,Recovery)crisis management theory,combined with the characteristics of rockburst accidents,a multi-level evaluation index system for rockburst emergency management capability was constructed.Secondly,the order relation analysis method(G1 method)-anti entropy weight method(A-EWM method)and combination weighting method(CW method)were used to determine the comprehensive weight of the index.The blind number theory was introduced,and the blind number matrix was established to process the qualitative index data,which improved the weighting mode of the traditional extension cloud model that experts intuitive scoring.Based on the principle of extension cloud model,the comprehensive cloud correlation degree under different levels was calculated,and the emergency management ability level was comprehensively analyzed and evaluated according to the requirement of maximum membership degree discrimination.Finally,the established evaluation model was used to analyze the rockburst emergency management capacity of three mines,and the results were compared with those of fuzzy mathematics and stochastic Petri net(SPN)evaluation models.The results show that the emergency capacity of the three mines is grade Ⅳ,which is consistent with the field investigation conclusions of experts,and the evaluation results of the three evaluation models are basically the same,which verifies the adaptability and effectiveness of the model in the evaluation of rockburst emergency management capacity.The evaluation model can provide a practical,reasonable and effective method for the quantitative evaluation of crisis management capability.
