The practical use of UAV systems in mine excavations and inspection works at LW “Bogdanka” S.A.

Abstract

This publication presents the application of the Elios 3 caged drone in underground geodetic measurements at the LW “Bogdanka” coal mine. Traditional surveying methods are increasingly being replaced by modern technologies such as laser scanners and unmanned aerial vehicles (UAV). LW “Bogdanka” mine has wide experience in the use of drones in surface surveys, which has enabled the implementation of these devices also in underground mine excavations. The Elios 3 aircraft, equipped with a 4K camera, thermal imaging camera, distance sensor and LiDAR technology, provides precise scanning of the environment and creating high-density point clouds. The SLAM stabilization system ensures the accuracy of measurements even in difficult conditions. This article focuses on the practical applications of the Elios 3 drone in the mine, such as inspections of coal storage tanks, assessment of the technical condition of dewatering roadways and measurements in hard-to-reach areas. The use of UAV significantly improves operational efficiency, reduces survey time and minimizes risks to employees. Thanks to LiDAR technology, Elios 3 accurately represents the details of the object being measured, which is crucial for maintaining and improving the mine’s infrastructure. The introduction of a drone for surveying at the LW “Bogdanka” mine brings numerous benefits, including increased workplace safety and advanced measurement capabilities in hard-to-reach and dangerous areas.
