An advancing support frame is connected to the face conveyor (9) via an advancing rod (7) engaging with the advancing cylinder (5). A lifting cylinder (10) is supported on the advancing rod (7), with which the base shoes (1) are lifted during the advancing process. The lifting cylinder (10) is guided so as to be able to move in height in longitudinal guides (15) on the inner sides of the base shoes (1). A U-shaped tension stirrup (18), whose shanks (19) directed towards the ground have elongated holes (20), is supported centrally by the lifting cylinder (10) and joined to the base shoes (1) via carrying bolts (21) fastened to them.
