Abstract
The relationship between Hardgrove grindability and coal microlithotype composition was studied for three coals from two eastern Kentucky mines. The purpose of the study was to further investigate the use of petrographic data as a predictor of mechanical properties important in mining and utilization. Samples were collected according to lithotype divisions. In general, monomaceral microlithotypes increased the grindability while the complex trimaceral microlithotypes decreased grindability. The bimaceral microlithotypes exhibited a varied influence depending upon their maceral composition.
