Langford and Rowe have introduced Terrestrial Laser Scanning to our list of professional surveying services that we have been supplying to the mining and exploration industry over the last 50 years.

The main advantages of laser scanning are:

Safety
As the scanner has a maximum range of 1000 metres it removes the surveyor from a potentially hazardous location e.g. the base of a pit face or the top of a steep stockpile. In most instances the surveyor operates the scanner from within a vehicle with the scanner mounted on the roof.

Accuracy
The scanner captures up to 11,000 unique points per second and the 3D surface generated from the scan data results in an extremely accurate volume calculation.

Langford and Rowe specialises in the following mine specific services:

Laser Scanning

• Laser scanning surveys of open cut pits and stockpiles
• Volume reports including rendered images of scanned surfaces giving a snapshot picture of the stockpile
• Supply 3D point cloud data and contours compatible with all software packages
• Subsidence monitoring
• As built surveys on earthworks, concrete and hard stand areas and portal entrances

GPS Surveys

• Control surveys using Static GPS techniques to transfer MGA co-ordinates and A.H.D levels onto new control stations to enable them to be included in the S.C.I.M.S database as an established survey mark
• 7 GPS receivers available for simultaneous use increasing accuracy and reducing field time

Our reputation is built around delivering professional surveying solutions using the latest technology in conjunction with appropriately trained Registered Surveyors.

We are currently supplying laser scanning services to coal mines between Mudgee and Singleton in the Hunter Region of NSW every month.
