A guide assembly is provided for guiding the scraper assembly around the curved conveyor section. A guide is fixed to the face side of the first straight conveyor portion, and a winning machine is reciprocable along the guide. A drive station is mounted on the goaf side of the first straight conveyor portion in the region of the curved conveyor section. A drive sprocket is rotatably mounted on the face side of the first straight conveyor portion in said region. The drive sprocket drives the winning machine via a drive chain. A drive shaft drivably connects the drive station and the drive sprocket. The drive station includes a drive motor whose axis of rotation is substantially parallel to the longitudinal axis of the first straight conveyor portion, and the guide is angled away from the first straight conveyor portion in said region.
