Performing and comparing regular 3D scans of the same areas is a highly efficient way to practice convergence monitoring in your underground mine. Doing this correctly means following a process that consists of two broad elements:
- Performing the actual scans with a mobile scanner that can rapidly generate accurate 3D point cloud data.
- Comparing scans of the same areas taken on different days with each other to determine if and where convergence is occurring, so appropriate action can be taken.
As is the case with so many aspects of modern mining, using the right equipment is key to the success of both of these activities.
Over the last few years, the uGPS Rapid Mapper™ has positioned itself as the scanning equipment of choice in mines all over the world due to its ability to generate dense, accurate data on the move. Robustness, low maintenance requirements, and ease of use add to the appeal.
As efficient as the uGPS Rapid Mapper™ is, any scanner is only as good as the data it produces, and that data is only as good as its ability to be quickly and easily processed in such a way that it leads to better management and decision making in the mine.
The software used with the uGPS Rapid Mapper™ scanner has always provided underground miners with top-class data for convergence monitoring and other purposes, but the recently released automated workflow for mobile convergence monitoring, which allows for the simple comparison of two or more uGPS Rapid Mapper™ scans, has raised the bar even further by allowing automated comparison of two or more uGPS Rapid Mapper™ scans to be made with only a few mouse clicks.
