The invention relates to a shield support assembly for underground mining, comprising a shield canopy and at least one floor runner 20 as supporting surface elements which are connected in an articulated manner and which can be pressed against rock by means of at least one hydraulic cylinder which is supported in bearing pans 8 on the shield canopy and floor runner 20, wherein each surface supporting element consists of a welded construction of welded-together components. In order to be able to support higher forces without increasing the overall weight, according to the invention at least one of the supporting surface elements comprises at least one hollow metal box profile 22 filled with a solid as a component of the welded construction 30. The invention also relates to the configuration of the floor runner and/or the shield canopy with at least one hollow metal box profile filled with solid, preferably concrete. |
