Abstract

The mine support system with floor (11) and roof (14) elements mounted behind a face conveyor, also has shield members (19, 20, 21) between them, used for packing debris (36) stowed at the rear. These members can be positioned to match the contour of this material (36). The floor and roof members are connected by telescopic supports (10) to match the height of the gallery, and the shield members can be folded or extended to adapt to this height. Thus they can form a nearly straight line for a high gallery, or the two members (20, 21) can fold together for low galleries. They are supported by a system of hinged swinging arms (24 to 33) for this adjustment.
