Design, kinematic and power requirements for longwall shearer, considering mining and geological conditions during low seams mining by longwall method, were discussed. On the basis of these requirements a concept of cutting longwall shearer for low seams was developed and required changes indispensable to be made in a design of longwall shearer and AFC were determined. The analysis of those concepts enabled to select most favorable version of longwall shearer which would effectively operate in the faces from 1 to 1.6 m.
