Abstract

1409022 Mine roof support equipment COAL INDUSTRY (PATENTS) Ltd 25 Jan 1974 [1 Feb 1973] 5027/73 Heading E1E In mine roof support equipment comprising a canopy 1 mounted on at least one prop 2, the canopy is provided with at least one inflatable, deformable member 14 mounted thereon. The prop 2 may be mounted on a crawler /cutter machine 4, 5, 6 which is also provided with an adjustable platform 15, 16 for positioning mine arches 9b, 9c. In a modification, see Figs. 4, 5 and 6 of the Provisional drawings (not shown), the roof support equipment is mounted on the floor rather than on the cutting machine and is advanced by runners connected to the machine by pivotal links. During advance the members 14 are deflated and control thereof is effected by a common assembly.
