The TILT Ranger was commissioned to scan three inaccessible stopes in an underground gold mine in the Mali. BVLOS (Beyond Visual Line of Sight) flights were conducted for some stopes.

The TILT Ranger was commissioned to scan three inaccessible stopes in an underground gold mine in the Mali. BVLOS (Beyond Visual Line of Sight) flights were conducted for some stopes.

Current solutions they use (boom-mounted CMS) can’t scan certain spots, creating blind zones. Such data is critical to mine operators and surveyors.

For two stopes, a 3D model was generated using the application of SLAM to the laser scan acquired. For the third stope, intense smoke prevented the scan from completion.
