The invention relates to a drive station for an underground plough system (10), in particular a coal plough system, comprising a machine frame (2), on which a plough stock (30) can be fixed, and a wedge groove (3) that is connected to the machine i frame (2) and that is provided with a chain channel for a plough guide unit (5') that has a plough chain and comprising an end stop on the runout section of the recovery plough. To facilitate the repair of a recovery plough, the end stop (51) is formed on an attachment (50) which can be dismantled from the assembled plough guide unit (5'), creating a repair section in the longwall-gallery transition of the wedge groove (3). The invention also relates to a repair method, in which the end stop (51) is dismantled and the recovery plough is driven into the repair section. |
