A method for driving tunnels, galleries, shafts or the like with a driving device (1; 2; 15), including: that a cutting head (4) rotating around a general axis of rotation (R) and having cutting elements directed essentially radially outwardly is applied against a rock surface to be worked. The rock cutting elements (13), are formed on cutting rolls (7) are brought to roll against the rock side during pressing against the rock and rotation of the cutting head (4), and the rock cutting elements during rolling are brought to cut sidewardly arranged grooves in the rock surface at a distance from each other. The invention also concerns a rotatable cutting head and a device and a rig for driving tunnels, galleries, shafts or the like.

Les éléments de coupe (13) de roche sont formés sur des tambours de coupe (7) amenés à tourner contre le côté de la roche pendant quils sont pressés contre ladite roche et que la tête de coupe tourne (4). Pendant leur rotation, les éléments de coupe de roche sont amenés à découper latéralement des saignées dans la surface rocheuse distantes les unes des autres. Linvention concerne également une tête de coupe rotative et un dispositif et un appareil de forage pour creuser des tunnels, des galeries, des puits ou analogues.
