Abstract: In view of limiting the height of shearer structure in thin coal seam mining,this paper puts forward a kind of electrical control system design of split type shearer for thin seam,which solves the problem that the shearer electrical control system influenced by the height of shearer.The electrical control system has been applied in MG100/130-PLDK shearer,and the application results show that system can meet requirements of various functions of shearer,which has realized automatic reciprocating coal mining and greatly increased the coal mining efficiency.
