摘要
煤炭资源的不断开发导致了煤质逐渐恶化,煤炭“细而杂”的特点正在日益凸显,提出如何保证这部分资源的高效回收是煤炭资源利用面临的重要问题;梳理了国内外微细粒煤分选技术的瓶颈问题;概述了重力分选、电选、浮选等方法在微细粒煤分选中的应用情况和研究进展;展望了未来微细粒煤技术与工艺的发展趋势和重点研究方向。
The continuous development of coal resources has led to the gradual deterioration of coal quality.The“fine and miscellaneous”characteristics of coal are becoming increasingly prominent.How to ensure the efficient recovery of this part of resources is an important issue facing the utilization of coal resources.The bottleneck problems of fine coal separation technology were summarized,the application and research progress of gravity separation,electric separation,flotation and other methods in fine coal separation were reviewed,and the development trend and key research direction of fine coal technology and process in the future were prospected.
