Services
Infrastructure Surveys
Our infrastructure surveys support mine planning by mapping access roads, rail networks, and power infrastructure. Using LiDAR and UAV drones, we generate precise digital terrain models to guide development. These surveys ensure efficient integration of mining operations with surrounding infrastructure.
Opencast Mining Surveys
We conduct opencast mining surveys to measure mined areas, volumes, and surface changes. Mobile laser scanning and drone photogrammetry provide rapid, accurate data for optimising extraction processes and compliance reporting in large-scale operations.
Underground Mining Surveys
Using SLAM handheld scanners and traditional methods, we create detailed underground mine models. These surveys monitor ground movement, assess pillar stability, and ensure equipment fit in tunnels, enhancing safety and operational efficiency.
LiDAR Scanning
LiDAR technology captures high-resolution topographic data for exploration and mine planning. It penetrates vegetation to map terrain, supports volumetric calculations, and integrates with BIM for precise 3D visualisations of mining sites.
UAV Drone Surveys
Drones enable rapid surveying of large or hazardous areas, producing georeferenced imagery and orthomosaics. This technology reduces risks and costs while providing real-time data for monitoring mine progress and environmental compliance.
