Abstract

The advancing mine support system for steep seams uses units with side by side floor members (2) with telescopic supports (5) carrying the roof members (1) with one set (14) connected at an angle to another set. This connection uses an arrangement of pistons and cylinders operated by a hydraulic control unit. On a base frame (8) mounted on the floor members (2) of the first set are attached two swinging cylinders (10, 11). One cylinder is attached by a holder to the roof member (16) of the adjacent set (12). The other cylinder (11) is connected to the adjacent floor member of the same set. The latter cylinder (11) is connected through a hydraulic lock and throttle to the supply line of the hydraulic control unit.
