Cross Roof Supports
These supports are part of the longwall system and support the mine working mine roofs at the crossing of the face and the gateway – the most sensitive point of the longwall mining system, and the face ends.
They enable the mechanisation of the following works:
- gateway roof support maintaining a constant support resistance
- road heading building in the crossing area just before the face front to the outside of workings
- moving the conveyor drive as face progresses
- automatic advancing of roof supports
- adjustment of the canopy to fit the variable shape of the roof in the crossing area
