Abstract
The drilling device is for creating bore-hole branches in unconsolidated rock. The device includes a fully-controllable pilot drill head with drill rods attached thereto. The pilot drill head has an opening on its periphery. The pilot drill head has further outlet openings through which a reinforcing-action drill suspension may be dispensed into a site where a bore-hole branch is to be created. An inner drill head is mounted for longitudinal movement within the pilot drill head and may be deflected out of the pilot drill head and its path by a deflection part within the pilot drill head. Upon its deflection, the inner drill head is directed through the opening on the periphery of the pilot drill head and into a bore-hole branch site.
