Method and device for working rock

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...

description 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.
