Previously, surveyors manually marked anchor drilling points, incurring both time and personnel costs, as well as machine downtimes and workflow delays. This manual process also posed safety risks in unsecured rock conditions. An automated solution enhances safety and efficiency by eliminating these challenges.

The TUnIS Navigation Rockbolter uses a total station on the tunnel wall, incorporating a 2-axis inclinometer to measure the drill rig carriage’s absolute position. Real-time drill rod position is calculated with sensors, displayed on the interface along with deviations from the planned anchor. The fully integrated system handles anchor pattern generation and the navigation of the drill rod as well as the evaluation and documentation of set anchors.
