煤矸石资源化利用途径及进展

Resource Utilization Ways of Coal Gangue and its Development

概述了目前国内外煤矸石的产生、危害及利用。总结了煤矸石利用的技术和方法,从不同的角度对其进行了分类,可以按资源回收利用分类,也可以按工程利用方法分类。根据煤矸石利用的深度层次可分为直接利用型、提质加工型和综合利用型三大类。据此细致全面剖析煤矸石资源化综合利用途径,并对我国煤矸石深度开发前景进行了展望。

Overviewing on the current domestic and abroad source, harm, use of gangue, the different classification methods from different perspective in the techniques and methods of gangue use are summarized. It could be classi- fied according to resource recycling, or according to the method of the project use. Focusing on the use of coal gangue according to the depth level classification, it can be divided into direct use of type, quality and processing and comprehensive utilization of three categories. Accordingly comprehensive and detailed analysis on available ways of comprehensive utilization of resources of coal gangue were roundly dissected, and prospected the depth of development of domestic coal gangue.
