Abstract
The statistical analysis of relationships between the composition, structure, and property characteristics of 63 test samples of coal from Ukraine, the Russian Federation, and countries outside the former Soviet Union was carried out. It was found that it is reasonable to separately predict the gross calorific value on a moist ash-free basis for the coals from Ukraine, the Russian Federation, and countries outside the former Soviet Union because of the different degrees of petrographic homogeneity of the test coals. Quantitative relationships were developed in order to forecast the gross calorific values on a moist ash-free basis with a required accuracy based on volatile matter, middle random vitrinite reflectance coefficient, and total fusainized components separately for Ukraine, the Russian Federation and countries outside the former Soviet Union.
