Laser scanning-based true condition of mine shaft and its lining

The article presents SLAM CHCNAV RS10 scanner data obtained in 2025 in an operating mine shaft. The list and execution speed of operations are reported, and the data interpretation is given. The processing order of the point cloud and the condition analysis of the test mine shaft are described. It is for the first time found that laser scanning determines many required parameters and characteristics which ensure safety, efficiency and facilitation of mining operations, namely: true condition and serviceability of operating mine openings; damage spots in support and lining, including visually unobservable areas; solid mineral output capacity both in open pit and underground mining; parameters of support and reinforcement in mine openings; rock mass stability, alignment of stopes and pillars; excessive volume of rock haulage per 1 m of stoping in case of increased design section of stopes, etc. Laser scanning with SLAM CHCNAV RS10 simplifies survey measurements and enhances efficiency of deformation monitoring. Periodic scanning of stopes exhibits deformation trends, high stress–strain areas in support and reinforcement system of stopes, as well as potential damage spots in support systems.
