Mine Surveying Technology: Modern Approaches

Mine surveying has undergone a technological revolution. Traditional total station and GNSS surveys are now complemented by drone photogrammetry, 3D laser scanning and automated monitoring systems.

Drone surveys enable rapid pit mapping and stockpile volume calculations without putting surveyors at risk on active mining faces. A single drone flight can capture an entire open-pit mine in minutes, delivering accurate 3D models and volumetric data within hours.

3D laser scanning provides detailed point clouds of underground workings and surface infrastructure, enabling precise as-built documentation and deformation monitoring.

GNSS RTK systems deliver real-time centimetre-level positioning for machine control, drill positioning and grade checking, improving efficiency and reducing rework.

At EN Geomatics, we integrate these technologies to provide mining clients with comprehensive surveying solutions — from pit mapping to stockpile volumes, deformation monitoring to mine development support.
