Abstract

1,153,800. Advancing mine roof supports. GULLICK Ltd. 20 Nov., 1967 [16 Dec., 1966], No. 56568/66. Heading E1P. In an advancing mine roof support assembly comprising two frames 10, 11 arranged in tandem and interconnected by an advancing jack, (not shown), for selective advance, an intermediate roof-engaging beam 17 is attached to one frame for advancement therewith and projects into area supported by the other frame to give roof support during advance of said other frame. The beam 17 is pivotally attached to one frame and supported on yoke members 16, 25 which in turn are mounted on props associated with both frames, see Fig. 2, (not shown).
