The working area of the boom(s) of an underground drill is a dangerous areas. The risk of injury due to rock fall, collision with moving boom(s), or rotating drilling rod is major, and statistics show several fatalities registered every year due

In order to reduce this risk, Sandvik has developed the Access Detector system for Tunneling drills.
Access Detector is a systems enhancing safer drilling operations by decreasing risks caused by human actions and errors. The system detects access from both sides of the drill rig thanks to a laser scanner located at the back of the machine.

When Sandvik Access Detector is actuated by a person entering the hazard zone, it warns the operator with a visual warning. The operator may continue the drilling operation normally but he/she must ensure that no-one is in the hazard zone.
