Continuous mining machines are self-propelled behemoths that rip coal, ores, rock, or sand from the mine face and load it onto conveyors or into shuttle cars. Mine cutting and channeling machines cut or channel along the face or seams of coal mines and stone quarries to enable materials to be removed from the Earth's surface.
