摘　　要：随着“双碳”目标的实施及投资者对矿山企业ESG指标的要求,在分析露天矿山道路综合成本时需要考虑环境成本。研究基于CRITIC法构建涉及材料、人力、机械、维护、碳排放、降尘、环境毒性、运输效率、构件寿命和轮胎损耗等10种因素的露天矿山道路综合成本分析模型。以紫金山金铜矿为例,通过信息承载量分析法,得到各指标的客观权重,降低指标间的相互影响。经计算,道路量化综合成本为:碎石路98.6元/m^(2),水泥路108.5元/m^(2),面层改性路62.9元/m^(2),整体改性路67.7元/m2。相对于碎石路和传统水泥路,改性道路在综合成本上具备显著优势,其中,面层改性路的综合成本优势超36%。With the implementation of China's"dual-carbon"target and increasing investor focus on ESG metrics,environmental costs must be integrated into the comprehensive cost analysis of open-pit mine roads.This study constructs a cost analysis model for the comprehensive cost of open-pit mine roads using the CRITIC method,incorporating 10 factors:material,labor,machinery,maintenance,carbon emissions,dust suppression,environmental toxicity,transport efficiency,component lifespan,and tire wear.Taking the Zijinshan Gold-Copper Mine as a case study,objective weights for each indicator were derived through information load analysis to mitigate inter-indicator correlations.Calculated quantitative comprehensive road costsare:gravelroads 98.6 yuan/m^(3),cementroads 108.5 yuan/mm^(3),surface-modified roads 62.9 yuan/m^(3),and overall modified roads 67.7 yuan/mm^(3).Compared to gravel and conventional cement roads,modified roads exhibit significant cost advantages,with surface-modified roads achieving a reduction in comprehensive costs of over 36%.
