Abstract
Longwall face equipment for use in extraction in underground mining, comprising electrohydraulically operated support units each having a support controller 6, with at least one power unit being provided that supplies at least two support controllers 6 of differing support units with power, and with a bi-directional coupler being connected between the power unit and the at least two support controllers 6 and providing galvanic isolation between the power unit and the support controllers 6 and/or groups I, II of support controllers 6. The couplers permit communication between the two support controllers 6 and/or groups I, II of support controllers. In order to simplify the arrangement of the face, the coupler 12 is integrated into the power unit 11 or is flanged directly onto the housing of the power unit.
