Bever Win 3D Profiler

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 in most cases 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 adviced 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

• Measure thickness between layers, like shot crete
