A device for guying a drift advancing machine within a drift has props which can be guyed between the drift roof and the drift floor and having articulated caps, connected to it. There are arranged at both sides of the longitudinal center plane of the machine at least one hydraulic cylinder-piston-aggregate between a supporting block fixed on the machine frame and the drift floor as well as between the supporting block and the drift roof in a guyable manner. The cylinder-piston-aggregates are articulatedly connected to floor supporting plates adapted to be pressed against the floor and to roof caps and are articulatedly connected to the supporting block, and the floor supporting plates and the roof caps are connected with the machine frame (1) via thrust supports.
