Convergence Analysis Made Easy

Using GeoSLAM Convergence Analysis provides rapid, regular, cost effective ways of understanding change.

Detecting velocity of change of rock movement is not only operationally important but can also be a critical indicator of potential slope / rockface instability. With GeoSLAM’s ZEB family of handheld laser scanners, you have the ability to get in and out of dangerous areas much faster than previously possible, as well as making it much easier to make repetitive scans. With a greater amount of information available due to the easier, cheaper and more frequent scanning, convergence analysis decisions can be made faster saving time, money and increasing safety. Exported data can also be used in existing mining software on site, meaning it can be analyzed using software that is already familiar to the team.

Being able to scan a heading or area of concern, every week or every day over a period of time gives us a good insight on how the surrounding rock is behaving. We can scan all of our headings before the main mining crew even get underground. The speed and simplicity of the scanner makes it our go to tool for all our monthly production mapping, surface stockpiles and other various survey missions on the mine.
– Simon Pollitt, Deputy Chief Surveyor at Boulby Mine.

Adjust to control

Adjust to control allows for the data to be georeferenced as part of the SLAM processing. This means all data exports will be in the right coordinates, and can be imported directly to the mine plan or for comparative analysis.

What makes GeoSLAM adjust to control different?

  • More accurate: GeoSLAM scanners are used with known control points and survey grade pins, rather than more traditional moveable targets. This reduces the margin of error within point clouds.
  • Save time: using known survey control points means there is no need to manually position individual targets before every scan. Data capture can then be repeated regularly, faster, easier and with no concerns that reference points are captured in different places each time.
  • Safer: in dangerous or inaccessible areas, targets are not required to be physically positioned on pre-defined control points prior to each scan. This reduces the time exposed to hazards and unsafe areas.

Third Party Software

GeoSLAM data is seamlessly used and integrated into 3rd party software such as MICROMINE, Deswik and other leading software packages. This means you can process it using the system you already have and are comfortable using.
