摘要 A wall supporting arrangement, especially for supporting mine gallery walls, comprises a supporting frame for a wall to be supported and including at least two frame elements located in a plane which is transverse to the elongation of the wall and are spaced from one another in this plane, and a plurality of shape-retaining shell-shaped connecting elements distributed along the frame elements and connecting the latter with one another in spacially fixed relationship. The supporting frame may include two such outer frame elements and two such inner frame elements connected with one another. In this case each of the connecting elements includes two shell portions connected with one another and including mounting formations for mounting the four frame elements with one another. The supporting frame may include a plurality of frame portions located laterally adjacent to one another in a circumferential direction of the supporting frame.
