Appalachian Coal: An Overview

Appalachian coalfields have been the predominant source of quality coals since the inception of commercial mining in the United States. In a broad sense, Appalachian coalfields can be considered those east of the Mississippi River, representing about 55% of total US coal production. In this special feature on Appalachia in MINING ENGINEERING, emphasis is given to the four coal-producing states of Pennsylvania, West Virginia, Virginia and (eastern) Kentucky. These four states produce more than 90% of the coal from the total Appalachian region, or about 40% of the total US coal production. Historically, Appalachia has been the principal source of coal for domestic industries and for export. There have been numerous fluctuations in the Appalachian coal industry during the past 20 years. Appalachia was affected by cyclical and structural changes in various industries, particularly the US steel industry, and changing world coal markets. It was also the region of more mine worker labor stoppages than other parts of the country. In general, the factors that affected Appalachian coal production over time are identical to those that determined changes in coal production nationally.
