Anthracite Geologically, the largest most concentrated anthracite deposit in the world is found in the Lackawanna Coal Mine in northeastern Pennsylvania, United States in and around Scranton, Pennsylvania. Locally called the Coal Region, the deposit contains 480 square miles of coal bearing rock which originally held 22.8 billion short tons (20.68 billion tonnes) of anthracite. (The geographic region is roughly 100 miles (161 km) in length and 30 miles (48 km) in width.) Because of historical mining and development of the lands overlying the coal, it is estimated that 7 billion short tons (6.3 billion tonnes) of minable reserves remain. The
