Mining Volumetric Measurement

Bureau Stephan is transforming Mining Volumetric Measurement

Offering proven, world-class solutions for the mining industry that are:
- Safe
- Efficient
- Accurate
- Cost-Effective

Accurate measurement of the volume and tonnage of extracted ore has always been complicated, time consuming, costly and unreliable.
Bureau Stephan UAV's are able to rapidly capture stereo imagery of open pit mines and their surroundings without the labor inefficiencies and safety issues normally associated with traditional volumetric surveys.
This imagery is processed into a dense point cloud using Bureau Stephan's alogorithms and photogrammetric software, generating a map with elevation values that may then be compared to previously existing elevation data. Efficient and cost-effective, this technology is being used by Bureau Stephan's customers around the world to accurately calculate tonnage extracted over a given time period.
