The assembly is arranged parallel to a shortwall mineral face, and a cutter is hauled along a guide on the assembly to cut the face. As the face is cut the assembly is moved towards the face by use of rams connected between the assembly and stay units located in roadways adjacent the face. The cutter may be a scraper bucket or a plough, and is hauled across the face by either one motor in one of the roadways, or by two motors, one located in each roadway. The cutter may be steered by use of jacks on the assembly located in the roadways.
