- We have developed a system that can profile through drilling mud
- Survey down 3,000’ (900 m) depth or more
- The system can be shipped by air cargo
The image above is the start of an air shaft.
- An in house designed system that can be deployed through 6” boreholes
- Depths of 1,000’ attainable
- Better than 0.5" accuracy, depending on range
This image shows the top of a 6” borehole used to ensonify a flooded mine stope.
BOREHOLE DELIVERABLES
- Survey 4 to 5 boreholes per day
- Tie multiple surveys together
- 2,500’ system tether lengths available
- Useful sonar range of 100 m
- Sound footprint, approx. 3% of range
- We use Total Stations and GPS units.
This image shows sonar XYZ data of a flooded 200 by 300 meter mine stope. Five different boreholes where used.
- Hardware and software was developed in house
- Produces an underwater 3D point cloud (XYZ data)
- Approximately 2 cm accuracy
This image is part of the deliverables of a deep excavated bridge pile sonar survey, note the angled soft stratum.
