ABSTRACT:
A transfer station from a longwall chain conveyor to a drift chain conveyor have upper and lower reaches which cross alternately. The upper belt section of the longwall conveyor comprises a scraper over the upper belt section of the drift conveyor. The working face side of the longwall conveyor has a plane guide for a coal plane and a plane chain which at least at the drift-side end of the longwall conveyor is guided via guide wheels to a gob-side drive unit. These two drift-side guide wheels are arranged with a vertical spacing from each other in the lower belt section of the longwall conveyor such that they form between them a passage for the chain belt and for the tappets of the longwall conveyor attached thereto. The drift-side guide wheels are arranged so close to the drift conveyor that in its drift-side and position the coal plane can transfer the won coal directly into the drift conveyor. In all, an especially compact plane chain deflection integrated into the longwall conveyor is realized.
