In auger mining, auger holes are bored horizontally into the coal seam from the last contour cut at the high wall. As the auger rotates and advances forward, coal is cut and pushed out of the hole by the rotating action of the auger. The action is similar to that of a carpenter boring a large hole in wood using an auger bit, and that is where ...

2. Coal winning • winning of coal by coal cutting machines, continuous miners or pneumatic picks produces a lot of dust. Dust produced by pneumatic picks can be reduced by about 50% by using wet pneumatic picks. Suppression of dust produced by coal cutting machines is usually done by water sprays incorporated in the machine.
