摘要
煤矸石是煤炭工业产生的大量废弃物,其大量堆放不仅占用土地,而且会造成严重的环境污染。本文从煤矸石的化学成分及矿物组成入手,详细讨论了煤矸石活性的来源;煤矸石的活化方式,包括热激活、物理激活、化学激活、辐射激活的机理及目前研究状况;煤矸石活化的评价方法;最后提出了目前煤矸石活化研究中存在的问题,如何更好激活煤矸石的潜在活性是研究者面临的一个难题。
The coal gangue is the massive solid waste which is the emissions of coal industry produces; the coal gangue stacks not only wasted the precious lands, they also cause the serious environ- mental pollution. This article contents the following aspects: The chemical composition and the mineral constituent of the coal gangue; the activation way of coal gangue which include the thermal activation, physics activation, chemical activation; the assess method of activation; in the last the, the authors point out how to improve the gangue's latent activeness is a difficult problem faced by the researchers.
