Production machines are essential in Room Pillar operations cutting coal and moving it out of the mine for processing. But it's the Roof Bolter that makes it possible for these machines to perform. Using a series of powerful bolts, these machines create selfsupporting roofs for Room Pillar mining operations. Highwall Miner
· 'Longwall' mining uses three basic system components: a cutting machine, usually a drum shearer but occasionally a plow, which moves back and forth across the coal face; an armored face conveyor (AFC), which moves the coal to the belt conveyor in the gate road for removal from the mine; and moveable roof supports that both support the roof behind the .

In machines which covered the full face, steering in the vertical plane could also be a major difficulty. The term "continuous" as applied to development machines has been one of the biggest misnomers used for mining equipment because, on development, they are usually anything but continuously cutting. The main delays mostly occur while roof ...

Currently, friction steel props and wooden props are still being used in most of the working faces in our coal mines, and at many of these faces, coal is won by drilling and blasting, and hand loading. Hydraulic props which can provide good support are being developed and are cheaper than power supports.
Here is a picture of a coal miner from 1814, when the Industrial Revolution was gathering pace. In the background, there is a steampowered locomotive, used to transport the coal in waggons along rails, and steampowered mine machinery, designed to help the miners bring the coal to the surface and to pump out water from the mine.
