基于层次分析法的黄金行业绿色矿山评价体系研究

Research on the evaluation system of green mines in gold industry based on the analytic hierarchy process

针对不同矿种矿山建立差异化的绿色矿山评价体系具有重要现实意义。基于层次分析法构建了黄金行业绿色矿山评价体系,以黄金行业绿色矿山评价体系为目标层,矿区环境、资源开发方式、资源综合利用等6个指标作为准则层,功能分区、矿容矿貌、矿区绿化等22个指标作为指标层,采用AHP层次分析法确定不同指标权重排序,确定较重要的准则层分别为资源开发方式、节能减排、资源综合利用,指标层分别为共伴生资源利用、绿色开发、节能降耗、开采回采率、选矿(冶)回收率、边开采边治理。本次评价结果可为黄金行业绿色矿山建设提供参考。

Establishing a differentiated green mine evaluation system for different types of mines is of significant practical importance.This study constructs a green mine evaluation system for the gold industry based on the analytic hierarchy process(AHP).The evaluation system sets the green mine evaluation index system for the gold industry as the target level,with 6 indicators as the criteria level such as mining area environment,resource development methods,and comprehensive resource utilization,22 indicators as the index level such as functional zoning,mine landscape,and mining area greening.The AHP method was employed to determine the weight ranking of different indicators,identifying important criteria levels such as resource development methods,energy conservation and emission reduction,and comprehensive resource utilization.As for the index level,key indicators include associated mineral resource utilization,green development,energy conservation and consumption reduction,mining recovery rate,beneficiation(metallurgy)recovery rate,and simultaneous mining and reclamation.The evaluation results provide a reference for the construction of green mines in the gold industry.
