摘要(Abstract)：

煤矸石是伴生煤炭开采和分选的副产品,堆积的煤矸石得不到适当利用,会带来环境污染和资源浪费。近年来我国愈加严格的环境法规和煤矸石潜在的利用价值促进了煤矸石利用研究,但忽略了由于中国煤炭分布面广,不同地域分布的煤矸石的物理化学成分会有所差异。以煤矸石的物化成分为基点,从煤矸石在能源行业、建筑行业、土壤应用行业和高值应用行业4个方面详细阐述了煤矸石物化性质对其利用途径的重要影响及应用过程中不同成分带来的环境二次污染风险,并指出了煤矸石综合利用领域的潜在问题和未来研究趋势。建议在选择煤矸石利用途径时,考虑利用途径对其基本物理化学成分要求的基础上,增加对煤矸石中可能产生环境二次污染风险的物化成分的要求,提高煤矸石的利用率和经济效益的同时,降低环境污染风险,两者相互权衡的基础上选择最佳利用方案,并建立对于后续环境二次污染的风险评估与追踪调查。
Coal gangue is a by-product of associated coal mining and sorting. The accumulated gangue cannot be properly used,which will cause serious environmental pollution and waste of resources. In recent years,the study of coal gangue utilization has been promoted due to the stricter environmental regulations and the potential use value of coal gangue in China. However,many studies have overlooked that due to the wide distribution of coal in China,the physical and chemical composition of coal gangue in different regions will be different. Based on the physicochemical composition of coal gangue,the importance of the physical and chemical properties of coal gangue on its utilization ways was elaborated from four aspects of the energy industry,construction industry,soil application industry and high-value application industry. The risk of secondary environmental pollution caused by different components was analyzed,and the potential problems and future research trends in the field of comprehensive utilization of coal gangue were pointed out. It is recommended that when choosing a way to use coal gangue,the requirements of the basic physical and chemical composition of the way should be considered,and increase the requirements for the physical and chemical components in the gangue that may cause secondary environmental pollution risks should be increased.In order to improve the utilization rate and economic benefits of the gangue,and reduce the risk of environmental pollution,the best use plan is selected based on the balance of the two,and the follow-up environmental secondary pollution risk assessment and follow-up investigation are established.
