CONTRIBUTION TO DETERMINATION OF COAL

in coal increases the HGI value, whereas the micronite and liptinite macerals decrease the grindability (Hsieh, 1976; Hower, 1987). On the basis of research of black coal from Kentucky Hower and Wild (1988) have derived that part of the HGI change can be explained by maceral composition, mainly by liptinite contents, which is the most
