ABSTRACT:
In a mineral mining machine of the shearer drum cutter loader type, a system for supplying water at the required pressures includes an intensifier to which in use mine supply water is fed, the pressure being enhanced in the high pressure chambers and the high pressure water being fed to jets on the end of the cutting drum. Water exhausting from the low pressure chambers is fed to the dust and frictional sparking suppression sprays arrayed along the surface of the cutting drum. The method of the invention consists of generating in a simple and effective manner the requisite water pressures utilizing an existing main supply.
