More Information
Summary:A cutting head assembly for excavating rock fragments from a mine wall is disclosed. In an embodiment, the cutting head assembly comprises a primary breakage mechanism actuable to apply, to the mine wall, a breakage force for breaking rock fragments from the mine wall. A surface of the cutting head assembly catches the rock fragments broken from the mine wall and has one or more ports associated therewith. A secondary breakage mechanism is operatively associated with the surface and actuable to apply a force for reducing the size of at least some of the rock fragments caught by the surface so as to allow at least the reduced size rock fragments to pass through a respective port for transportation to downstream processing.
