Through the analysis of industrial indicators,coal and rock,Oya expansion,base fluidity,ash composition,and optical structure of coke of Ukrainian coking coal,and compared with the quality indicators of domestic coking coal,the results show that the degree of metamorphism of Ukrainian coking coal is between 1/3 of coking coal and coking coal,with general cohesiveness,small number of colloids,high softening temperature,narrow plastic interval temperature,low expansion and fluidity,high inertia ratio,high ash composition MBI,and low ash and low sulfur coal.The coking optical structure is mainly fine-grained mosaic structure,coarse-grained mosaic structure and inert structure,which is quite different from that of domestic coking coal.
