SPECIAL FOCUS: DRONES


Drones head


hree-dimensional (3D) laser scanning has become a de facto standard in underground mining operations for a variety of reasons, including accurate excavation


audits, ground support inspections, rock face condition assessments and general surveys. Also, with the new push towards implementation of Internet of T ings (IoT) principles and methods in the mining industry, 3D laser scanning and mapping are gaining widespread acceptance amongst technology developers and users.

UNDERGROUND T


Syed Naeem Ahmed discusses 3D laser scanning and mapping of underground mine cavities with aerial drones


T e Tilt Ranger drone is based on tilting


rotor technology. T e combination of tilting rotors and wheels allows the system to be rolled on the ground as well. T e scanner on the drone (V-Scan3D) weighs 930g and is capable of performing both stationary and mobile scans. T e mobile scan processing is accomplished through a simultaneous localisation and mapping (SLAM) algorithm. First tests were performed to see if multiple stationary scans can be done from the drone


fi rm Inkonova have jointly introduced an unmanned aerial vehicle (UAV), the Tilt Ranger, which is designed for underground mines with the capabilities of scanning and mapping mine cavities in three dimensions. Here, we discuss a case study to understand the eff ectiveness of this system in scanning drifts and stopes in diff erent underground mines.
