Beschreibung
Zusammenfassung:	An arrangement for extracting extraction products in caving in which the extraction product is extracted downwards through an extraction funnel into an extraction path and from this is transferred onto an extraction conveyor arranged in a conveyor path, in which arrangement the extraction path extends transversely between the conveyor path and an auxiliary path parallel to this, a loading ramp is arranged in the extraction path which forms a ramp surface orientated transversely to the conveying direction of the extraction conveyor and inclined towards it. The extraction path is provided with a rail guidance attached to the bottom and extending in the area between the auxiliary path and the conveying path, on which the loading ramp is guided and along which it can be moved by a displacement drive (20) in the direction of the conveyor path and in the opposite direction.
