The Appalachian region is most associated with coal mining, particularly in states like West Virginia, Kentucky, and Pennsylvania.

The Appalachian region, stretching through parts of the eastern United States, is historically and economically linked to coal mining. This area, which includes states such as West Virginia, Kentucky, and parts of Pennsylvania, has some of the richest coal reserves in the country. Coal mining has been a vital industry in Appalachia for centuries, providing jobs and energy resources. However, this reliance on coal has also raised environmental and health concerns, with practices like mountaintop removal mining causing significant ecological damage. Despite the decline in coal demand, Appalachia remains an iconic region for U.S. coal production.
