Methods of assessing coal strength are compared on the basis of a literature review. The Hardgrove grindability index HGI is the most expedient. There is a close relation between HGI and the coal quality as well as the power consumed in grinding. Accordingly the HGI values of coal samples may be used to optimie the crushing of coal as a preliminary to coke production
