大宗固体废弃物是资源综合循环利用的核心领域,煤矸石作为国内排放量最大的工业固体废弃物,其综合利用是新时期无废城市及生态文明建设的必然要求。采用资料查阅、调研实践及统计分析相结合的研究方法,在了解陕北侏罗纪煤田煤矸石的主要来源及危害以及煤矸石基本特性的基础上,系统剖析煤矸石的研究与应用现状。同时,立足陕北实际,基于产业生态化和生态产业化循环发展理念,结合调研,提出煤矸石掺烧协同工业发电,煤矸石回填协同地质环境治理,煤矸石破碎协同土壤生态修复,煤矸石制备协同建材应用,地上-地下生态修复利用的思路和路径,为煤矸石大宗固废的综合利用及产业绿色低碳发展提供参考。

Bulk solid waste is the core field of comprehensive recycling of resources. As the industrial solid waste with thelargest discharge in China, its comprehensive utilization is the inevitable requirement for waste-free city and ecological civilization construction in the new period. On the basis of combining data review, research practice and statistical analysis, theresearch and application status of coal gangue is systematically analyzed. At the same time, considering the reality of northern Shaanxi, based on cycle development concept of industrial ecological and ecological industrialization, and combined withpractice research, we put forward the proposals of the gangue blending collaborative industrial power generation, ganguebackfill collaborative geological environment management, gangue broken collaborative soil ecological restoration, ganguepreparation collaborative building materials application, and the ground-underground ecological restoration. Our study provides reference for the comprehensive utilization of coal gangue bulk solid waste and the green and low-carbon developmentof the industry.
