Longwall mining is a deep mining technique capable of fully extracting huge panels of coal, frequently up to 1,500 feet wide and two miles long. Coal shearing machines known as “continuous miners,” remove a long wall of coal in a single slice as hydraulic jacks hold up the roof above and in front of the machine.
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (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.
Longwall mining machines are about 800 feet (240 meters) in width and 5 to 10 feet (1.5 to 3 meters) tall. The miners extract "panels" -- rectangular blocks of coal as wide as the mining machinery and as long as 12,000 feet (3,650 meters). Massive shearers cut coal from a wall face, which falls onto a conveyor belt for removal. As the miner
