Abstract: A transfer station in the face end region between a face conveyor and a gate conveyor in the region of a drive for the face conveyor, the gate conveyor being attached to the face conveyor such that it can be moved pivotably to a limited extent relative to the latter. The transfer station being provided with a receiving plate that is arranged on a subframe of the drive for the face conveyor, which receiving plate is provided with a bearing seat, in which a specific connection pan element of the gate conveyor is mounted such that it can be moved pivotably relative to the face conveyor or its drive about a pivot axis which is defined by the bearing seat. The construction has the particular advantage that the pivoting bearing is readily accessible and has to transmit only low forces which result substantially from the loading of the gate conveyor.

Abstract: A traction carriage for an underground mining plow, comprising a traction carriage body which can be inserted into a cavity in a plow body and which on the rear side of a guide recess has a front part whose ends pointing in the direction of travel form stop surfaces for interacting with counterstop surfaces in the cavity of the plow body. According to the invention, a damping device having a damping action in both directions of travel is integrated into the front part of the traction carriage. In order to provide a low-maintenance damping device which allows a more favorable transmission of force between the stop surface on the traction carriage and the counterstop surface on the plow body, the coupling piece can be moved relative to the stop surfaces counter to the restoring force of a damping system of the damping device that is arranged between the stop surfaces.

Abstract: A chain guide for a driving chain of a winning plow or the like, the chain guide being provided with a chain guide element which is arranged in spatial proximity to the sprockets at a driving or return station and is against the chain transversely to the direction of movement of the latter, provision is made according to the invention for the chain guide element to have at least one pressure roller which can be adjusted against the chain links of the driving chain, as a result of which the wear on the chain guide element is considerably reduced.

Abstract: A plough guide trough for plough guides of chain-drawn coal ploughs, comprising two superposed chain guide ducts separated by an integrally cast sliding spacer member, with a top guide strip, a bottom guide beam and a bottom slideway for guiding the plough. The top chain guide duct is covered by a front wall comprising the guide strip and merging into the guide beam and a slot lead-through for a plough guiding hook or plough knife is formed between the guide beam and the slideway. Pockets in the front wall receive a toggle coupling for neighboring plough guide troughs, wherein the front wall, the guide strips, the guide beam, the pockets and a back wall comprising the slideway form a one-piece casting extending over the length of the plough guide trough.

Abstract: The invention relates to a highwall mining system comprising: a cutterhead (2), a train of conveyor segments (6) connecting to the cutterhead (2), a base structure (5), and a gas guide (P1-P4) running from the base structure (5) to the cutterhead (2) for guiding inert gas to the environment of the cutterhead (2). The invention also relates to a conveyor segment (6) for use in a such a highwall mining system, and to a method for providing this highwall mining system.

Abstract: A baseplate plow guide section for guiding a baseplate plow. The baseplate plow guide section includes a guide element arranged on a packing side of a conveyor trough delimited by lateral profiles and a return trough delimited by trough profiles of a conveyor. The guide element has an upper chain channel and a lower chain channel provided with a guide slot for the plow baseplate. Reception pockets for toggle heads of connecting toggles for connection of adjacent baseplate plow guide sections are formed on the guide element. The guide element includes a casting which extends over a length of the baseplate plow guide section and on which the reception pockets and/or the packing-side trough profile of the return trough and/or a guide part for the plow baseplate of the baseplate plow are cast as integral components.

Abstract: A coal plough for underground mining has a plough body that is guided along a plough guide. The plough body has at least one foot piece which receives a sliding skid. The sliding skid has at least one contact surface formed on its underside, which surface slides on a rail of the plough guide when the sliding skid is in its operating position. The sliding skid has first and second wear inlays on an underside which is arranged in the area of the highest load. The sliding skid can withstand high mechanical loads for a longer period of use.

Abstract: A plough guide for underground mining ploughs, with angle plates (5), whose extended arm (8) is fastened on the working face side to the conveyor pan (3) of a chain scraper conveyor and whose base arm (7) towards the face, supported on the ground (6), forms a sliding track for the plough, with upper and lower chain channel slides (11, 12) for the plough chains separated by distance pieces (9) fastened preferably at a distance from each other on extended arms of the angle plates, with a cover (15) closing the chain channels (12, 11) to the working face side and which can be pivoted towards the face, having at least one abutment part (21), which can be fixed on the plough guide and released, and with a guide rail (18) arranged on the plough guide at a distance from the sliding plough track. The abutment part (21) of the cover (15) is clamped between the angle plate (5) and a securing part (30) at a distance from the cover (15) screwed onto the angle plate (5).
