Abstract
A continuous mining machine has a drum assembly rotatably supported thereon generally transversely to the axis of the mining machine frame. The drum member has a cylindrical outer surface supporting cutter bits for sumping into the mine face. Between the cutter bits are radially extending vanes for moving the mined material around the cutter drum assembly and for dissipating gases from the area adjacent to the cutter drum assembly.
