ABSTRACT:
The rotor of a cutter for removal of material from a mine face has a large number of externally mounted bits each of which is adjacent to a discrete spray nozzle serving to discharge one or more streams of water at a pressure in the range of several thousand bars. The nozzles receive water from conduits which are installed in an annular chamber between the skirt of the substantially cup-shaped rotor and the adjacent end portion of the drive shaft for the rotor. Groups of conduits receive pressurized water from manifolds which are installed in the chamber and each such manifold receives pressurized water from a discrete conduit which, in turn, receives pressurized water from a distributor rotating at the discharge end of a stationary pipe in an axial bore of the shaft.
