Abstract

1424276 Advancing mine roof support systems BOCHUMER EISENHUTTE HEINTZMANN & CO 10 May 1973 [19 May 1972] 22439/73 Heading E1P In an advancing mine roof support system for a longwall face comprising a plurality of support units each having a sleeper resting on the floor, an arcuate casing shield 9, a cantilever roof bar 10, at least one prop 12 and one or more advancing rams 20 for coupling each of the sleepers to a rigid face conveyor 5, the conveyor is provided with one or more guide bars 19 per sleeper and the configuration of the guide bars and sleepers is such that relative sliding movement therebetween is exclusively confined to the direction of their common longitudinal axis. The advancing ram may be disposed within the guide bar 19 or mounted centrally of two sleepers each associated with an individual guide bar, see Fig. 4 (not shown).
