Abstract：

The petrographic analysis, coal size and coal quality analysis of different raw coal and coking coal were made. A comprehensive analysis result shown that the coal size distribution is similar the Gates-Gandin-Shuzman and Rossin-Rammer distribution. The change of maceral composition in different size grade coal has a regularity. It will be effect the cohesiveness, sulfur and ash yield of coking coal. This result can be use to improve the coal preparation process and rising coke quality.
