Performance profiling

The Atlas Copco Tunnel Profiler is a fully integrated 3D scanning system that tells the drill rig operator, following a five-minute scan, how the excavation conforms to the pre-planned design. Using this system under- and overbreak and shotcrete thickness can be checked and corrected at an early stage.

The objective is to drill and blast to an optimum contour at the lowest total cost, as any deviation from the specified profile can be costly and time consuming to correct later on. After setup at the face, the Atlas Copco Tunnel Profiler conducts 3D automatic scanning of a defined section. The resulting data is immediately available and displayed in the Rig Control System, RCS, with a coordinate accuracy of +/- 2cm.

An additional benefit of the Atlas Copco Tunnel Profiler is the possibility of using the laser as a convenient, new method of rig navigation.
