ABSTRACT:
A plough for winning material in a longwall working is formed with guide surfaces which co-operate with a guide provided at the face-side of a longwall conveyor. The plough is driven by means of a chain passing round a pair of sprockets positioned at the ends of the conveyor at the goaf-side thereof. The plough is provided with a sword plate which passes underneath the conveyor, and the sword plate is provided with a coupling member for engaging the plough drive chain. the plough includes a plough body provided with cutters at one end thereof. The coupling member is set back relative to said cutters by a sufficient distance to enable the plough to win material up to the appropriate end sprocket when the plough is moving in such a direction that said cutters are leading cutters.
