摘　　要：从煤的组成与结构角度简述了煤的变质程度、元素组成、含氧官能团类型、表面电性等因素对煤可浮性的影响,概括了煤的结构特征与可浮性的关系;指出煤的孔隙率、煤中矿物与有机质的结合状态等物理结构亦是影响其可浮性的重要因素,应在今后的研究中予以考虑。This paper gives a brief introduction about the influence of coal metamorphism,element composition,oxygen-containing functional group type,surface electricity behavior and other factors on coal floatability from the point of view of coal composition and structure,summarizes the relationship between coal structural characteristics and floatability,and points out that porosity of coal,the combination state of minerals and organic matter in coal and other physical structures are also important factors affecting its floatability,which should be considered in the future research.
