Abstract

1394675 Advancing mine roof supports GULLICK DOBSON Ltd 5 July 1972 [16 July 1971] 53424/71 Heading E1P In an advancing mine roof support system comprising at least two supports arranged side by side and each having advancing means 28, 29 operable to selectively advance a forward part relative to a rearward part, each forward part includes a spill plate structure 34 extending transversely of the support and having at at least one side edge thereof a device adapted to co-operate with the adjacent side edge of the said plate structure 34 of the adjacent support whereby said structures may be coupled together so that one support can serve as an anchorage for the other during advance. The spill plate structures are coupled by pin and slot means 34a allowing a degree of vertical movement. The roof member 23 of the forward support is guided by wire ropes 24 moving through slots in guide lugs 26, 27, the ropes being anchored as at 25, 25a to the cantilever roof members such as 17 of the rearward support. For a modification involving single unit supports which operate in pairs, Fig. 9 (not shown), should be referred to.
