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/m2,水泥路 108.5 元/m2,面层改性路 62.9 元/m2,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 costs are: gravel roads 98.6 yuan/m?, cement roads 108.5 yuan/m , surface-modified roads 62.9 yuan/m2,and overall modified roads 67.7 yuan/m2. 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 %.
