Abstract

A walking roof-support for a mine gallery comprises two sets of arches each including plurality of interconnected segments 1 on which are mounted outwardly extendable plate segments 6. One set of arches I, III, IV complete by overlaps the other set II, II and the arches of each set are connected together by flexible tie bars 8 and telescopic guides 5. The set I, III, IV are also connected by two I section rails 9 by pins 19 extending between slotted plates 11, 13, 14 at the arch crowns. The set II, II have rollers 7 mounted above and below the rails 9 between plates 12. When the arches of one set have been contracted by the operation of rams 2, 4 they can be moved on the rollers 7 by two advancing rams 10. To the back of the roof support is pivoted a jib 21 for lifting fixed frames into position. This is operated by a ram 16 acting on a rope 20 which passes over a pulley 25. <IMAGE>
