煤矸石综合利用与资源化处理研究进展

Research Progress on Comprehensive Utilization and Resourceful Treatment of Coal Gangue

煤矸石的资源化综合利用对于控制煤矸石污染、促进生态文明建设具有重要作用。由于煤矸石产量巨大,需要不断发掘新的利用途径。利用煤矸石制作填充材料,发电,生产砖、水泥等建筑材料是目前国内主要的无害化处理手段,从中获得高附加值产品是未来努力的方向。本文对不同类别、不同特性煤矸石的利用方式进行了综合分析,再结合现有的利用技术,在具有高附加值的农用肥料、微生物肥料和以分子筛及吸附性材料为代表的化工产品等方面提出煤矸石综合利用的发展建议,旨在为国内外煤矸石综合利用与资源化处理提供新的发展思路。

The resource-oriented and comprehensive utilization of coal gangue plays an important role in making coal gangue pollution under control and promoting the development of ecological civiliza-tion. It is necessary to continuously explore new ways of utilization of coal gangue due to its large products. In the present, the main innocuous disposals of coal gangue are electricity-generation and production of fill materials and building materials like bricks and cement. In the future, the upward trend is to make high value-added products out of it. In this paper, through a comprehensive analysis of the current utilization of different categories and characteristics of coal gangue, we give suggestions on the comprehensive utilization of coal gangue in the aspects of the products with high value-added, including agricultural fertilizer, microbial fertilizer and chemical products, such as sorptive materials. It is hoped to provide some new insight into comprehensive utilization and resource-oriented treatment of coal gangue in the world.
