SUPPORTING STRUCTURE OF FRAMING FOR APPLICATION IN HIGH AND MEDIUM DIPS

摘要

The excavation frame (1) according to the invention for use in inclined and semi-inclined stratification with a tilted working face, is constructed in the manner of a narrow extraction frame to whose footwall threshold (8) a vertically adjustable supporting bracket (21) is connected on the stowing side, which supporting bracket (21) bears the inclined stowing wall (3) which is also vertically adjustable. Preferably, the stowing wall is arranged centrally with respect to the extraction axis. The downward side wall (49) of the supporting bracket can form a sliding track for a laterally extendable support skid (45) of an adjacent extraction frame. In order to stabilise the extraction frame consisting of a two-plunger frame, a connecting arm system (32) is used which is expediently connected via a universal joint (34) to the roof bar of the hanging roof.
