Abstract

1,201,150. Advancing mine roof supports. GULLICK DOBSON Ltd. 22 Nov., 1967 [16 Dec., 1966], No. 56569/66. Heading E1P. In an advancing mine roof support assembly each prop unit has a forwardly projecting member 21 carrying guide rails 23 for a winning machine and a ramp plate 25 forming part of a conveyor for transferring the coal to a road-head conveyor. The member 21 is in the form of a cantilever which is pivoted to a bracket 19 and supported by a hydraulic ram 22. Coal on the ramp 25 is fed by an endless chain carrying paddles into a trough 26 communicating with the road-head conveyor, see Fig. 1 (not shown).
