ABSTRACT:
A roadheader type mining machine (1) comprises a self-propelled chassis (6), an elongate boom (9) having a longitudinal axis (10), rotary cutting head (15) having a plurality of water spray nozzles (17). The boom (9) is of a two-part construction comprising an inner part (18) that is non-rotatable about the boom longitudinal axis (10), that is supported from one end (8) on the chassis (6), and that carries towards its other end (14) bearing means (19) for rotatably supporting an outer part (20) that axially extends from said inner part (18). Power means (59) is carried by the non-rotatable part (18) to rotate the rotatable part (20) about the boom longitudinal axis, while the rotatable part (20) is provided with pumping means (39) and a bearing ring (50) that is carried by the rotatable part (20) eccentrically with respect to the axis (10), whereby phased water supply to the nozzles (17) is controlled by suitable angular rotation of the rotatable part (20) about the axis (10) to cause consequent rotation of the ring (50).
