(1) extremely thin coal seam: thickness is less than 0.8m, the minimum cut-off height in 0.65-0.8m can only be used to climb the bottom.

(2) thin coal seam: when the thickness is 0.8-1.3m and the minimum cutting height is 0.75-0.90m, the riding trough type is selected.

(3) medium thick coal seam: the thickness is 1.3-3.5m, choose medium power or high power shearer.

(4) thick coal seam: the thickness is more than 3.5M, adapt to the large height of the shearer should have slant function, in order to adapt to the large height of the fully mechanized mining face geological relics mining conditions change. The shearer and the conveyor should have large block coal crushing device to ensure the normal work of the shearer and the conveyor.

Secondly, but also according to the nature of the roof and floor. The main influence roof management method and support equipment choice, unstable roof control top distance should be as small as possible, choose narrow fuselage shearer and can advance support support. The soft floor is supported and guided by the conveyor sliding planer, cantilever support type of floor climbing shearer, riding trough shearer and hydraulic support with lower contact pressure of the floor.
