Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 0.6–6.0 m (2 ft 0 in – 19 ft 8 in) thick). The section of rock that is being mined, known as the longwall panel, is typically 3–4 km (1.9–2.5 mi) long, but can be up to 7.5 km (4.7 mi) long and 250–400 m (820–1,310 ft) wide.
It occupied over 265 buildings and 14,000 acres (57 km 2) of Redstone Arsenal, near Huntsville, Alabama. In October 2010, as part of the Base Reallocation and Closure (BRAC) process, RTTC was combined with the Aviation Technical Test Center from Fort Rucker to form the U.S. Army Redstone Test Center.
