Void Scanner applications and deployment

Void Scanner is the most reliable, cost-effective way to carry out the regular mapping of underground voids, stopes, shafts and ore passes.

Carlson Software Inc has acquired the Quarryman, Boretrak, C-ALS, Void Scanner, Merlin and ILM laser module product lines previously owned by Renishaw plc. Please visit our Carlson webpage for details.

A range of applications for mining and civil engineering

While primarily a high-speed, low-cost cavity monitoring system, used in the ‘routine' measurement of underground mining and excavation progress and 3D mapping, Void Scanner applications also include:

  • Gallery, void and stope surveying
  • Project profitability / feasibility planning
  • Ore pass monitoring
  • Mine design management
  • Waste and ore stockpile management
  • End-of-shift extraction volume scanning
  • Compliance, environmental and safety management
  • Storage silo volume measurement
  • Underground blast planning
  • Drive surveys
  • Face modelling
  • Pre- and post-excavation mapping
