Mobile Convergence Monitoring, Australia

Enhance underground mine safety with the right choice of scanner.

Mobile Convergence Monitoring in AustraliaAs the underground mining industry in Australia continues to grow and develop, driven by traditional demand (coal, gold and other minerals etc.) as well as more recent demand driven by technological growth (rare earth elements), there will be an increasing requirement for mines to go deeper and wider and produce more tonnage to stay profitable and meet rising demand.

As tunnels are constructed at ever greater depths or bored through less-stable material to reach new ore deposits and increase the scope and production of the mine, they are subjected to ever-increasing stresses. Under these conditions, there is a very real risk of convergence that, if not monitored and appropriately addressed, could lead to rock fall or total collapse.

Convergence monitoring can be performed by one of two means, or a combination of both:

  • Geotechnical instruments mounted directly into the rock walls or roofs of tunnels (e.g. contractometers, extensometers, instrumented cable bolts etc.)
  • Surveying scanners, usually laser-based (LiDAR)

Laser scanners used for convergence monitoring in Australian underground mines can be either of a fixed (often tripod-mounted) type or a mobile type.

The uGPS Rapid Mapper™ 3D mobile mine scanner is the industry leader when it comes to on-the-fly, point cloud data scanning that provides an accurate, efficient way to practice mobile convergence monitoring.

The uGPS Rapid Mapper™ mobile mine scanner can be used to provide an additional layer of convergence monitoring, validating results obtained from installed geotechnical instruments, or it can be used in areas where the use of geotechnical instrumentation is not required or impractical – e.g. new development or sensitive areas where rapidly available, accurate convergence data is required.

This easy-to-use, versatile scanner is rugged, low-maintenance, and purpose-built for use in underground mines, and can generate accurate, dense 3D point cloud data on the move (e.g. while attached to a vehicle that is driven through the mine), making it the ideal choice of equipment for performing mobile convergence monitoring.
