Abstract

The invention relates to so-called block bracing of a shiftable conveying and/or winning installation, in which the hydraulic bracing cylinders are supported in an articulated manner on prop abutments on the goaf side behind the conveying and/or winning installation. In this arrangement, the prop abutments are coupled to support assemblies of the hydraulic self-advancing support system of the winning operation, preferably in such a way that they form with these support assemblies a self-advancing unit. The support assemblies preferably consist of support groups of known type in which two support units (support frames) are connected via a self-advancing mechanism. In this arrangement, the prop abutments are in each case coupled to only one of the support units of the support group.
