摘要
煤矸石是采煤和洗煤过程中排出的固体废物 ,是一种在成煤过程中与煤层伴生的含碳量较低、比煤坚硬的黑灰色岩石。本文在阐述煤矸石对环境危害的同时 ,着重指出了煤矸石的综合利用途径。变废为宝 ,开展煤矸石资源化利用研究前景广阔。
The coal gangue is a kind of solid wastes from coal mining and separating, which is also a kind of grey-black rock harder than coal, characterized by low content of carbon and association with coal seams during coal accumulation. The impact of coal gangues on the environment has been expounded in the paper, and the comprehensive utilization purposes of coal gangues have been emphasized to point out as well. The foreground for the research on the resources utilizations of coal gangues is very great.
