The models estimate all capital and operating costs typically associated with the preproduction and production phases of a coal mining project, and may be applied either to existing mines or to proposed mine openings. The models are an updated and computerized version of the original EPRI Coal Mining Cost Models (EA-437, Vols. 1 and 2).

Underground Coal Mining Underground mining involves opening one or more portals or shafts into the earth that follow or intercept coal seams that are too deep for surface mining methods. Two main methods of underground mining are practiced in Pennsylvania: Room-and-Pillar: Generally used for seams that are relatively flat or gently dipping.
