the term coal quality is used to distinguish the range of different commercial steam coals that are produced directly by mining or are produced by coal cleaning. 3 generally, coal quality for steam coals (i.e., coal used for electricity generation) refers to differences in heating value and sulfur content , although other characteristics such as grindability or ash fusion characteristics are
the coal as a fuel and cause environmental problems in its use. the depth, thickness, and configuration of the coal seams determine the mode of extraction. shallow, flat coal deposits are mined by surface processes, which are generally less costly (per ton of coal) than underground mines of similar capacity. strip mining is one of the
