Read the full article
The paper describes the structure of the mobile directional survey station, algorithms and software used for continuous directional survey of the relative position of shaft trajectories of the underground opening blasting borehole group. New engineering solutions obtained at the station design are presented and analyzed. The results of the station field tests in ore excavation environment are presented.
