FIELD: mining.
SUBSTANCE: in one of the longwall coal-cutting machine embodiment it contains the first section of the carrier with mounted thereon the first cutting arm and the second section with mounted thereon the second cutting arm. The first and the second sections of the carrier are connected by the hinged joint. The longwall coal-cutting machine device is mounted on the rail. The retaining shoe extends from the hinged joint and contains at least one retaining element, which engages with the rail. Thus longwall coal-cutting machine forms the transverse axis, extending generally from the first cutting arm to the second cutting arm, the retaining shoe is made with ability to move perpendicularly to the transverse axis.
EFFECT: improved longwall coal-cutting machine guidance according to the operating horizon.
