Abstract

1,219,908. Advancing mine roof supports. GULLICK DOBSON Ltd. 14 June, 1968 [13 Sept., 1967], No. 41868/67. Heading E1P. In an advancing mine roof support assembly comprising a front unit 9, 10, 11 connected to a rear unit 12, 13, 14 by a pivotal connection 15 and a pivoted ram 16, a roll of flexible decking 4 is supported by the front unit for paying out beneath the rear unit in a system of extraction for thick seams worked stage by stage in slices or webs, see Fig. 1 (not shown). In a modification the rear unit is supported from the front unit by a rigid cantilever like extension secured to the base of the latter or the rear unit may have an auxiliary, ram positioned between the rearmost props of the assembly for sliding movement relative thereto, see Figs. 3, (not shown), and Figs. 4, 5, 6 (not shown), respectively.
