To establish a clear correlation between the coking quality of coals and blends and their microlithotype constitution, typical Kuzbas coals were examined under a reflected light ore microscope and a complex descriptive parameter was sought. Distinctions were made between the following microlithotypes: vitrite, clarite, duroclarite, clarodurite, durite, fusite, semivitrinite, mineralized coal, and dirt. Multiple regression equations were developed which adequately describe the correlations between the visco-plastic property indices of coal blends, the quality of the coke, the x-ray structural parameters, and the petrographic parameters of the coals. With the help of these equations the behavior of microlithotypes during carbonization of coal was discussed.
