This is very high quality bituminous coal rated at approximately 15,000 BTU (16,000 kJ).
Over 60 coal towns were once located there, supported by independent commercial districts at Beckley, Oak Hill, Mount Hope, and Fayetteville.
The mainline of the Chesapeake and Ohio Railway ran right through the center of this coalfield, with spurs branching off in many directions, and rail yards were maintained at Quinnimont, Raleigh, and Thurmond, WV.
The Virginian Railway's main line also passed through the western side of the field as well.
These companies recruited native born whites, immigrants from Southern and Eastern Europe, and African-Americans from the South to work in their coal mines and railroads.
