摘　　要：基于生命周期评价(LCA)方法,考虑全球变暖、颗粒物质形成、陆地酸化、人体毒性、矿产资源耗竭、化石能源耗竭等6类环境影响指标,分别量化利用干基与湿基煤矸石替代原燃料生产水泥熟料的环境影响,评估相对于完全利用化石燃料生产硅酸盐水泥熟料的减污降碳潜力,选取“处置/利用1t煤矸石”为功能单位,对比煤矸石资源化利用与传统处置的环境影响,量化煤矸石资源化利用带来的环境效益,为煤矸石在水泥行业的资源化利用决策提供数据与方法支撑。This paper uses the Life Cycle Assessment(LCA)method to consider six environmental impact indicators,including global warming,fine particulate matter formation,terrestrial acidification,human carcinogenic toxicity,mineral resource scarcity,and fossil resource scarcity,and quantifies the environmental impact of utilizing dry and wet coal gangue as a substitute for raw materials to produce cement clinker,evaluating the potential for reducing pollution and carbon emissions compared to fully utilizing fossil fuels to produce Portland cement clinker.The“disposal/utilization of 1 ton of coal gangue”is selected as the functional unit,and the environmental impact of coal gangue resource utilization and traditional disposal is compared,quantifying the environmental benefits of coal gangue resource utilization,providing data and methodological support for the decision-making on the resource utilization of coal gangue in the cement industry.
