Abstract (en)
A gathering head (117) for a mining machine (100) positionable at a forward end of the machine. The gathering head comprises a base (119), a back plate (124) and sidewalls (120). The sidewalls are both tapered inwardly in the widthwise direction of the head from a forward end (301) to a rearward end (205) and outwardly relative to the base (119) from a lowermost region (323) to an uppermost region (322). Accordingly the requirement for additional gathering arms at a base region of the head is avoided.
