During servicing, the "continuous" miner moves to another face. Some continuous miners can bolt and rock dust the face, two major components of servicing, while cutting coal, while a trained crew may be able to advance ventilation, to truly earn the "continuous" label. However, very few mines are able to achieve it. Most continuous mining ...
The mining museum contains Australia's most comprehensive collection of coalmining artefacts, including coal cutters, coal loaders, continuous miners and underground transports.

Minimal manning at the face - particularly during the cutting of coal, only one man at a time was allowed at the face (the continuous miner driver) Armoured cabins were built on continuous mining machines - these cabins were thought to be able to protect the operator in the event of an outburst. (This was subsequently proven incorrect.)

Continuous miners – electric, self-propelled digging machines that cut material using carbide-tipped bits on a horizontal rotating drum. Longwall shearers – a material-cutting machine that moves back and forth on an armored face conveyor running parallel to the coal or other material being mined.
After the late 19th-century coal miners in many countries were a frequent presence in industrial disputes with both the management and government. Coal miners' politics, while complex, has occasionally been radical, with a frequent leaning towards far-left political views.
More modern room and pillar mines use a more "continuous" method, that uses machinery to simultaneously grind off rock and move it to the surface. [12] Other processes, such as backfill, where discarded tailings are unloaded into mined-out areas, [9] can be used, but are not required. Retreat mining (below) is an example of a process like this.
