Underground monitoring

Maptek Sentry helps improve safety underground.


Maptek laser-based Sentry system monitors underground operations to record and report on subsidence and convergence.

Operations can identify movement across multiple zones and set notification thresholds. The high resolution laser scan data is ideal for geotechnical applications, providing operations with a holistic safety and risk management system.

Underground operations can apply Maptek laser scan imaging solutions to rock bolt, development heading, tunnel and stope survey and mapping applications.

Sentry is compatible with the R3 series laser scanners

Underground monitoring applications

  • Monitor subsidence and convergence, including infrastructure
  • Safely monitor around crushers and conveyors
  • Pre- and post-surface scaling and shotcreting applications
  • Conduct geotechnical analysis for risk management
  • Operates in low light for underground and night time monitoring
