A reactive-track type propulsion system for a mineral winning machine comprises a sprocket chain located along the path of intended movement and a sprocket wheel with teeth meshing with the chain. The wheel is mounted on the machine and driven to propel the machine along the chain. The chain has horizontal oval links and vertical links which have planar end faces which make driving and rolling contact with the flanks of the teeth of the sprocket wheel.
