Face conveyor for extraction plants and trough element for said face conveyor

A face conveyor for extraction plants for the extraction of minerals by an extracting machine, the face conveyor comprising:

• a continuous conveyor, which is formed by a conveyor chain with entrainment plates that are connected to chain links and which, when conveying, circulates in two runs that travel in opposite directions, one run of which forms the outward run and the other run forms the return run, each of which are guided in trough portions by trough elements, which are arranged in a row connected so as to be inextensible and angularly displaceable in a restricted manner;
• guides on each trough element for the extracting machine, the guides comprising at least one first guide on a working face side and one second guide at a spacing from a goaf side;
• wherein the first guide on the working face side is secured on the trough element between the outward run and the return run, and wherein 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, wherein the entrainment plates comprise transport plates, which form a plate conveyor conveying belt for removing minerals extracted by the extracting machine.
