Probing ahead of the face with percussive drilling

• Uncertainty regarding the nature of ground conditions can exist even after a well conducted site investigation. Fortunately, valuable information can be obtained by drilling horizontally from the face in the direction of the tunnel using microprocessor-based monitoring equipment. The equipment scans, measures, processes and store drill performance parameters. By establishing penetration rate, torque, trust, etc., an early evaluation of ground condition is possible. Probing ahead has been successful in several tunneling site investigations, among them was in Glodberget in Sweden
