Research and Application of Green Mine Construction Evaluation Model
In order to further improve the scientificity and reliability of green mine construction evalu-ation,aiming at the complexity of green mine construction evaluation and the difficulty of accurate quantita-tive evaluation,a comprehensive evaluation method based on improved variable weight extension is pro-posed.By comprehensively considering the main influencing factors of green mine construction evaluation,6 first-level indicators such as mining area environment and the corresponding 26 second-level indicators are selected to construct a multi-level green mine construction evaluation system.Then the blind number theory is used to improve the traditional qualitative index assignment method.Based on the variable weight theory,the constant weight of the index is modified.According to the extension principle,the construction level of the green mine is determined by calculating the comprehensive membership degree.The evaluation results of green mine construction in a gold mine engineering application example show that the green mine construc-tion grade of the gold mine is 'good'.Compared with the evaluation results of fuzzy comprehensive and grey clustering models,the conclusions of the three evaluation models are consistent and consistent with the actu-al situation.It is verified that the model has adaptability in the evaluation of green mine construction,which can provide new ideas for the evaluation of green mine construction.
