ABSTRACT:
A coal plough has an elongate plough body which is provided with cutters at each end. The plough body is supported at each of its two ends, by a flat narrow skid on a plate of a plough guide. The skids constitute wear-resistant members and are connected to the plough body in a readily replaceable manner. The skids are so shaped that they guide the plough in the lower zone of the plough guide, and establish connection between the plough and the plough drive chain.
