A water supply system for a mining machine (1) of the continuous miner type comprises at least one rotatable mineral cutting drum (5); at least one water supply arm (9) adapted, in use, to extend forwardly from the mining machine (1) and terminating in a ring (6), the internal periphery (10) of which ring (6) is in close proximity to a portion of the external or internal arcuate periphery (53, 52) of the cutting drum (5). A circumferential water supply chamber (44) is defined between the internal periphery (10) of the ring (6) and the portion of the drum; and water seating means (32) extends between the ring (6) and the portion of the drum (5) to minimise water leakage from the chamber (44). A water delivery port (45) is provided in the or each water delivery arm (9) for supplying pressurized water from a remote supply source to the chamber (44); and a water distribution network (38-41) of the drum (5) is in water flow communication with the chamber (44). The invention also includes a mining machine (1) provided with such a water supply system.
A water supply system (8) for a mining machine (1) of the continuous miner type, said system comprising:
A mining machine of the continuous mining type, comprising a crawler chassis (2) with a pair of spaced-apart, elevatable drive arms (4) pivotable about a common transverse axis, projecting from the front of the chassis (2) and carrying a mineral cutting means comprising a pair of end cutting drums (5) and a central cutting device, wherein at least one of said end cutting drums (5) is provided with a water supply system (8) comprising:
