Abstract: 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.

Abstract: In the arrangement in accordance with the invention for extracting extraction products in caving in which the extraction product is extracted downwards through an extraction funnel (10) into an extraction path (11) 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 (13) and an auxiliary path (12) parallel to this, a loading ramp (16) is arranged in the extraction path (11) which essentially forms a ramp surface orientated transversely to the conveying direction of the extraction conveyor and inclined towards it.

Abstract: An entry conveyor including a conveyor pan formed by a plurality of pan sections that are hingeably connected to each other, at the two ends of which conveyor pan drive stations and/or return stations for a scraper chain are provided. Each pan section includes a top strand delimited by lateral profiles and the conveyor base and a bottom strand for the scraper chain as well as receiving elements for a pan section connecting mechanism, which elements are disposed outside of the lateral profiles. A pan strand including a plurality of pan sections that are disposed behind each other is provided in the conveyor pan, which sections are hingeably coupled via a center swivel bearing disposed on the center longitudinal axis of the conveyor pan or the pan sections. The invention also relates to the pan sections with the center swivel bearings.

Abstract: In the method according to the invention and the arrangement or according to the invention for extracting extraction products in underground mining operations using the caving method, the extraction products (20) collapsing in an upper gate area (10) are extracted via at least one extraction funnel (13) or the like into an extraction path (14) driven below the gate and are transported away therein by means of an extraction conveyor (15). According to the invention the extraction funnels (13) are arranged laterally beside the extraction conveyor (15) and lead at their lower end into a ramp surface (17) inclined towards the extraction conveyor, the extraction products extracted from the gate through the extraction funnels being transported slidingly over the inclined ramp surface to the extraction conveyor.
