摘要
陕西省地处黄河上游地带,煤炭资源丰富,然而煤矿在采掘过程中产生大量的煤矸石固体废弃物,煤矸石的堆积不仅造成土地资源的浪费,而且产生了各种生态环境污染。因此,煤矸石固废的资源化利用是实现煤炭产业可持续发展的必经之路。不同地区的煤矸石由于成岩地质作用及次生风化作用的不同,导致其物化性质有所不同,如矿物结构、外貌特征及化学组成有所差异。采集陕西省五个典型矿区的煤矸石样品,系统研究了煤矸石的物理学结构、化学组成和矿物成分基础理化性质,进而为陕西地区煤矸石资源化利用提供科学依据。
Shaanxi Province is located in the upper reaches of the Yellow River,which is rich in coal resources.However,the mining process generates a significant amount of coal gangue solid waste.The accumulation of this waste not only wastes land resources but also causes various environmental issues.Therefore,the resourceful utilization of coal gangue solid waste is essential for the sustainable development of the coal industry.Due to differences in lithological and secondary weathering processes,the physical and chemical properties of coal gangue vary across different regions,including differences in mineral structure,appearance,and chemical composition.Therefore,coal gangue samples from five typical mining areas in Shaanxi Province are collected,and the physical structure,chemical composition and basic physical and chemical properties of coal gangue are systematically studied,so as to provide a scientific basis for the resource utilization of coal gangue in Shaanxi Province.
