Continuous miners, used primarily in 'room and pillar' mining and also to prepare roadways in a 'longwall' systems, have incrementally improved over the last 20 years (Fig. 7.11).But they are not advancing in automation as quickly as longwall equipment, with the exception that they are more often remotely controlled by an operator, rather than by an operator sitting on the machine.
Room and pillar mining operations rely on many types of equipment to get work done quickly — this includes scoops, face haulers, feeder breakers, continuous haulage machines, roof bolters, continuous miners and more.
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 0.6–1.0 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 (1.9–2.5 mi) long and 250–400 m (820–1,310 ft) wide.
