Abstract
The invention relates to a drive station for an underground plough system, in particular a coal plough system, with a machine frame to which a plough box can be fastened, and with a wedge trough which is connected to the machine frame and is provided with a plough guide device, which has chain channels for a plough chain, and also a plough end stop on a runout section for a winning plough. In order to facilitate the repair of a winning plough, the plough end stop is formed on an attachment which can be dismantled, when the plough guide device is mounted, to produce a repair section in the longwall-gallery transition of the wedge trough. The invention also relates to a repair method in which the plough end stop is dismantled and the winning plough is moved into the repair section.
