摘要

The northern and central Appalachian coal basin is a major source of coal for the nation and the export market. The basin continues to be an important source of coal, currently producing about 40 percent of US coal output, almost entirely high-Btu bituminous coal. The basin still contains an estimated 46 Gt (51 billion st) of recoverable coal reserves, including 4.5 Gt (5 billion st) at active mines. However, some of this tonnage has limited commercial value because of its high-sulfur content.
