Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically – m (2 ft 0 in–3 ft 3 in) thick). The longwall panel (the block of coal that is being mined) is typically 3–4 km (– mi) long and 250–400 m (820–1,310 ft) wide.
The spray zone moves with the mining machine back and forth through the longwall, and is considerably more effective than the standard dustcontrol systems built into shearers. This system has helped many mines around the world to greatly reduce dust and to stay well within the respective approved limits. longwall dust suppression system
