Abstract

1438796 Advancing mine roof supports K M GROETSCHEL 14 June 1973 [14 June 1972] 28419/73 Heading E1P In an advancing mine roof support assembly comprising a pair of interconnected outer frames A adapted to be selectively advanced relative to an inner frame B by jack means 18, a forward cross-beam 3 and a rearward crossbeam 4 respectively interconnects the two forward and rearward sockets of the outer frame, the rearward cross-beam 4 extends over the floor beam 7 of the inner frame B with the rearward prop socket 9 of said inner frame B positioned rearwardly of the rearward cross-beam 4 and the forward prop socket 8 of the inner frame positioned forwardly of the said rearward cross-,beam 4-the distance between the cross-beams and the distance between the sockets 8, 9 being equal to the length of two complete forepoling steps. The assembly is provided with alignment jacks 25, shield means 13 and stabilising means incorporated in the roof superstructure for details of which, Fig. 6 (not shown), should be referred to.
