Wall and stability monitoring

Maptek solutions help improve safety by early detection of surface movements and moisture leakage in highwalls and tailings dams.

Maptek laser-based monitoring solutions allow operations to safely survey pit highwalls and dam walls from remote standoff. Stability analysis can be conducted on high resolution Maptek laser scans and accompanying digital imagery for monitoring risk.

Laser scanning and modelling tools provide a safe and reliable solution for mapping tailings dams to manage risk. Repeated mapping allows close management of the integrity of tailings dams and shows regulatory bodies that safety issues are being considered.

The Sentry wall monitoring system allows operations to identify surface movements and analyse deformation trends. Maptek laser scan data is combined with sophisticated Sentry software to track, analyse and monitoring movement over time.
Wall monitoring data enables operations to gain a better understanding of how materials behave during excavation. Maptek spatial imaging solutions can be applied to all survey, monitoring and conformance reporting tasks.

Sentry is compatible with Maptek XR3, Maptek LR3, Maptek SR3, I-Site 8820 and I-Site 8200ER/SR laser scanners
