摘要
煤矸石是煤炭开采及加工过程中产生的一种大宗工业固体废弃物,长期露天堆积不仅占用宝贵的土地资源,还会造成严重的环境问题从而危害人类健康.随着生态文明建设的深入推进及环保要求的不断提高,煤矸石的减量化、无害化处理及资源化利用已成为煤炭行业的迫切需求.本文从煤矸石的资源化综合利用等方面综述了煤矸石处理和利用的研究进展,总结了煤矸石处理的现状和存在的问题,探讨了煤矸石处理和利用的高质量发展趋势,最后提出了煤矸石全元素精细化及高值化利用等建议.
Abstract
Coal gangue is a kind of bulk industrial solid waste produced in the process of coal mining and pro-cessing.Long-term open-air accumulation not only occupies precious land resources,but also causes serious envi-ronmental problems and thus endangers human health.With the deepening of ecological civilization construction and the continuous improvement of environmental protection requirements,the reduction,harmless treatment and re-source utilization of coal gangue have become an urgent demand of the coal industry.This review summarizes the re-search progress in the coal gangue treatment and utilization from the aspect of comprehensive utilization of coal gangue,highlights the current situation and existing problems of coal gangue treatment,discusses the development trend of coal gangue treatment and utilization,and finally puts forward suggestions on the refinement and high-value utilization of coal gangue.
