Abstract
A face conveyor includes a continuous conveyor formed by a conveyor chain with entrainment plates that are connected to chain links and which, when conveying, circulates in an outward run and a return run, each of which are guided in trough portions by trough elements, which are arranged in a row. Guides provided on each trough element include a first guide on a working face side and a second guide at a spacing from a goaf side. The first guide on the working face side is secured on the trough element between the outward run and the return run. The outward run and the return run extend in a laterally offset manner with respect to each other, and the trough portion guiding the entrainment plates in the outward run is open on the working face side.
