| The green mine construction has been implemented in china for many years,as more and more green mine pilot units will face the problem of acceptance issue,however,the evaluation criteria are still in the exploratory stage and has not yet drawn up a unified and widely recognized evaluation index system and evaluation methods.Therefore,china's mineral resources industry urgently needs a comprehensive,scientific and targeted green mine construction evaluation indicators and evaluation methods to comprehensively evaluate the development of green mines construction condition.In view of the effect of green mine construction,through field investigation and expert consultation,based on AHP&entropy weight method,a comprehensive evaluation system of green mine construction combined with quantitative and qualitative indexes is constructed in metallurgical mines.And taking an open-pit mine as an example,an empirical study on the comprehensive evaluation of green mine construction were achieved.The main research results are as follows:(1)Through the field investigation and related expert consultation,combined with the 9 basic conditions of national green mine construction,a multi-objective and multi-level comprehensive evaluation index system for metallurgical mines is constructed based on quantitative indicators and qualitative indicators.(2)The combination of analytic hierarchy process and entropy weight method is used.The weight of comprehensive evaluation index of multi-objective and multi-level is studied,and the subjective and objective composite weight of green mine construction evaluation index is obtained,which improves the accuracy and credibility of evaluation.(3)Based on the established evaluation index system and evaluation method of green mine construction,the comprehensive evaluation of green mine construction in an opencast iron mine is empirically studied.The results show that the green mine construction in this mine is in good condition,but it should be further strengthened and perfected in terms of energy saving and emission reduction.At the same time,it verifies the feasibility of the index and the accuracy of the evaluation method.Through the research of green mine construction evaluation,the effective index system and accurate evaluation method for green mine construction in iron ore industry were constructed,and the relevant countermeasures and suggestions were put forward.This paper is expected to have a positive significance to promote theconstruction and evaluation of green mine. |
