Bever 3D Profiles

Guidance and quality control of tunnel profiles

There is a general objective at tunneling to drill and blast a profile with optimal profile at the lowest cost. That is : low overbreak and low risk for underbreak (which is costly to remove at a later stage in the project).

The Bever 3D Profiler is normally mounted on the jumbo rig and can be operated by the drill rig operator.

3D Profiler features

• check tunnel profile as a normal operation during round drilling/blasting
• scanned 3-dimensional profiles is measured and points on profile is displayed to operator
• operator is advised about underbreaks
• overbreak is calculated and presented to operator
• recorded profile can be displayed on PC and documented on paper
• underbreak may be drilled/blasted during next round
• profile can be drilled with less margin with less risk for costly underbreak removal
• reduced need for surveying work, later profiling
• scanning may be done while drilling next round

• operator on rig can operate the profiler without expert assistance

• Can also be delivered as a self contained unit
