Abstract

1335630 Mining minerals ENVIRONMENT/ ONE CORP 19 Oct 1971 [20 Oct 1970] 48476/ 71 Heading E1F [Also in Division F1] In apparatus for producing a high energy liquid jet, which comprises a chamber 11, Fig. 1, and an outlet nozzle 12, a shock wave is electrically created in the liquid to eject the latter through the outlet 12. Liquid is supplied to the chamber 11 through a line 13 and one way valve 14 and electrodes 16, 17 are energised from a capacitance 23 via a switch 22 which is also linked via a sensor 26 to a shutter 24. The electrodes 16, 17 are provided with sleeves 20, 21 and insulation 18, 19. In a second embodiment, Fig. 2 (not shown) liquid is supplied to the chamber 11 through a port (31) and under the action of a piston (30). The jet apparatus shown in Fig. 7 is an embodiment suitable for mining purposes in which case a plurality thereof are mounted in a vertical array on a movable strand (40) together with metal cutting tools (41) and/or infra-red heating units (53) to assist break-up of the surface to be mined, Figs. 3, 4 (not shown). The apparatus comprises plates 31, 32 between which is bolted a plate 33 defining the chamber 11 with its outlet nozzle 12 and inlet 14 for liquid. The electrodes 16, 17 are housed in respective insulating sleeves 18, 19. The jet apparatus may be arranged in a circle to act as a drill. The outlet nozzle 12 in a modification may be controlled by an eleotromagnetically actuated solenoid valve. The jets from the apparatus may be used to drive water soluble resin into the bedding planes of a mine wall, the resin causing creaking of the wall along the balding planes to facilitate mining of the wall by following cutter means.
