Abstract
1502284 Goaf stowing GULLICK DOBSON Ltd 21 May 1975 [6 Nov 1974] 47942/74 Heading E1F Apparatus for packing debris in mines comprises a series of packing or ramming devices having pressure fluid-operated driving means and a control system, for said driving means, including pressure fluid-responsive valve devices and operating means therefor connected in the control system so as to provide for the selective or predetermined operation of any one or any one of at least one set of groups of the packing or ramming devices within the series. Preferably the control of the apparatus is obtained by incorporating in the control system means to provide for the transmission of bi-directional pressure fluid signals for operation of valves controlling the piston cylinder units of the devices whereby one or some of the devices are operated before numerically preceeding devices in a progressively numbered series of such devices. The system involves manually operable valves for sending pressure fluid signals to the valves controlling the piston-cylinder units and means for transmitting pressure fluid signals from a unit actuating device to the control valve of another unit-actuating device to operate said control valve due to pressure build up in the hydraulic circuitry of the first device when the unit has been fully actuated.
