In the late 1980s and early 1990s, the Electric Power Research Institute (EPRI) sponsored research on coal handleability to assist its member utilities when purehasing coal fur power plants. This research evaluated a wide variety of coals and their properties, and It resulted in the development of an index, a simplified tester, and a classification system for coal buyers to use in developing coal specifications. Investigators selected the ratio of the unconfined yield strength to the bulk density of a coal sample as the coal handleability index, and a simplified tester was developed to determine the handleability index of coals at power station locations. The classification system included a combination of the amount of fines (-0.5 mm) present in the coal and the moisture content, the most important parameters influencing a coal's handling properties.
