ABSTRACT:
A mineral mining installation comprises a mechanical mining machine (such as a plough or a shearer) and a hydraulic winning machine. The hydraulic winning machine has a plurality of high-pressure nozzles and a high-pressure pump for supplying the nozzles with high-pressure water (or other hydraulic fluid). Means are provided for driving each of the two winning machines independently of the other along a mineral face. This permits the mechanical winning machine to operate at its optimum, high speed rate without interference from the slower moving hydraulic winning machine. The pump is preferably a multiple radial-piston pump powered by an electric motor. Both electric power and water may be supplied to the hydraulic winning machine via pick-up arms on the machine and supply channels extending along the face.
