Longwall mining - SourceWatch

Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single sl (typically 1-2 m thick). The longwall "panel" (the block of coal that is being mined) is typically 3-4 km long and 250-400 m wide. Longwall mining produced 176 million tons of coal in 2007, about 15 percent of total U.S. production.
