CA 2132785

ABSTRACT The prop headboard is used to support an inflatable grout bag on the head of an elongate prop. The headboard has a timber frame which presents a planar support surface suitable for supporting the inflatable grout bag. Bag-retaining flaps made of flexible fabric material extend from opposite edges of the headboard. These flaps are folded over the grout bag and serve to centralise it on the headboard and to restrain it from rolling out sideways during inflation and thereafter. The invention also concerns a prop system in which the headboard is used, and a method of supporting a hanging wall in a mine working.
