Longwall shearers cut away the face of a coal seam in longwall mining operations by mounting over an armored face conveyor (AFC). They are equipped with cutting drums positioned against the coal seam by ranging arms powered by hydraulic rams. They can weigh more than 100 tons, travel at speeds up to 30 m/min, and cut away slices of coal seams up to 100 cm thick.

The use of coal cutting machines, first introduced in the 1870s, accelerated in the early decades of the twentieth century. In 1915, percent of the total national coal was mechanically cut; the percentages were higher in the four main producing states (in 1900): Illinois, Ohio, Pennsylvania, and West Virginia (Dix 1977, p. 20).

Garforth invented a coal cutting machine and owned the Diamond Coal Cutter works at Wakefield. He took out patents in relation to parts of the Weg apparatus and sold over 100 units. Whereas Garforth the inventor of coalcutting machines sought profits, Garforth the inventor of breathing apparatus was guided seemingly by more altruistic motives.
