摘　　要：铁尾矿综合利用是矿山环境恢复治理与绿色发展的重要部分。为了实现铁尾矿综合利用效益的最大化,对铁尾矿综合利用效益进行评价。基于层次分析法和模糊数学模型,以定性分析和定量分析相结合的方式,构建铁尾矿综合利用评价指标体系。选取了经济效益、社会效益和生态环境效益3类因素以及潜在资源价值、综合利用率、投资回报率、尾矿利用方向产值、行业政策形势条件、增加就业程度、财政收入贡献量、矿山环境改善程度、减少区域水土污染、降低尾矿库安全隐患和二次污染程度11个指标,建立了较为系统的铁尾矿综合利用效益评价体系。根据构建的效益评价模型,攀西某矿区铁尾矿综合利用效益等级属中等(Ⅲ级),隶属度为0.56;经济效益和社会效益为中等(Ⅲ级),隶属度分别为0.75和0.60,环境效益等级为较差(Ⅱ级),隶属度为0.58。本文研究为矿区尾矿综合利用向矿山环境改善和可持续发展提供了合理和科学的依据。Comprehensive utilization of iron tailings is an important part of mine environmental restoration and sustainable development.In order to maximize the comprehensive utilization benefit of iron tailings,the comprehensive utilization benefit of iron tailings is evaluated.Based on analytic hierarchy process(AHP)and fuzzy mathematical model,the evaluation index system of comprehensive utilization of iron tailings is established by combining qualitative analysis and quantitative analysis.The authors select the economic,social and ecological environment benefits for three first-level indicators,three first-level indicators include potential resource value,comprehensive utilization efficiency,return on investment,the output value of tailings utilization direction,the industry policy situation,increase employment and revenue contribution amount,mine environment improvement,reduce the area of water and soil pollution,the reduction of the tailings safety hidden trouble and degree of secondary pollution,establish a system of iron tailings comprehensive utilization benefit evaluation system.Based on benefit evaluation model of the building,a mining iron tailings in Panxi comprehensive utilization benefit level is medium level(Ⅲ),membership degree is 0.56;economic and social benefits for the medium(Ⅲ),membership degree is 0.75 and 0.60 respectively,level of environmental benefits for the poor(Ⅱ),the membership degree of 0.58.It is a reasonable and scientific basis for the comprehensive utilization of tailings to improve the mine environment and sustainable development.
