煤矸石资源化利用研究进展

Research progress on coal gangue resource utilization

煤矸石是采煤和洗煤过程中排放的固体废弃物,是一种在成煤过程中与煤层伴生的一种含碳量较低、比煤坚硬的黑灰色岩石。结合煤矸石组成成分,对煤矸石进行资源化利用,在充分利用资源的同时能有效避免其对生态环境造成污染。本文主要对煤矸石资源化利用研究进展进行分析,以期对煤矸石资源化利用起到指导性作用。

Coal gangue is a solid waste discharged during the process of coal mining and coal washing. It is a black-gray rock with low carbon content and harder than coal in the process of coal formation. Combined with the composition of coal gangue, resource utilization of coal gangue can effectively avoid pollution to the ecological environment while making full use of resources. This paper mainly analyzed the research progress of coal gangue resource utilization, in order to play a guiding role in the utilization of coal gangue resources.
