Abstract

A fabricated rotary, mineral cutting head (1, 1A, 1B) comprises an outer, barrel element (4) supported from a central hub (3), the hub (3) being provided with a water supply bore (9) connectable to a source of high pressure water, a plurality of apertures (10) provided at circumferentially spaced locations around the barrel element (4), and a plurality of water conveying spokes (11, 11A, 11B) each penetrating an aperture (10) and extending radially, or generally so, from the central hub (3) to make fluid flow connection thereto at an inner spoke end with the source of pressurised water, and provided at an outer spoke end with a water discharge nozzle (22) to emit a water spray or jet of desired configuration. The invention also includes a rotary, mineral cutting head comprising a plurality of holders for mineral cutter picks, and an internal network (29) of water conveying piping, including at least one water inlet branch (30) connectable to a source of high pressure water, at least one distribution branch (31) in fluid flow communication with the inlet branch (30), and a plurality of spokes (11B) in fluid flow communication with the distribution branch (31) and associated with the individual pick holders.
