    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 (ie, coal used for electricity generation) refers to differences in heating value and sulfur content , although other characteristics such as grindability or ash fusion characteristics are25/03/2018· Both these techniques include different types of mining, but all f them use giant machines to remove coal from under the ground They are two most basic methods that miners use to quarry coal While surface mining is used for coal that can be found anywhere from the surface to 200 feet below, underground mining is used for coal that is located lower In surface mining, the top layer is removedCoal Mining –The 2 Most Basic Techniques Of ExtractionThe thickness of the coal seam, the depth and inclination of the coal seam, the nature of roof and floor strata, and the amount of gas contained both in the coal seam and the roof and floor strata are all important for selection of the mining method Mining difficulties are greatly increased if seams are extremely thick or thin or are steeply inclined Longwall mining additionally requiresAppendix E: Coal Mining and Processing Methods | Coal
