A coal-mining machine is advanced along a face conveyor by providing a rack extending along the conveyor and a plurality of advancing units. Each advancing unit includes a hydraulic motor to rotate a drive wheel while meshing with the teeth of the gear rack. The advancing units arranged side-by-side along the mining machine have curved end faces to abut against one another. Runners are provided on the advancing units at the opposite ends of the mining machine which extend partially around the rack for guiding and maintaining the drive wheel engaged with the teeth of the rack.
