NAVIGATION SYSTEM FOR LHD MACHINES
Load, haul and dump (LHD) machines are used in mines to carry ore from loading point to dumping point. This paper presents techniques developed to automatize the work of LHD machines. The work concentrates on navigation of the .machines using dead reckoning, artificial beacons and distance measurement from vehicle to tunnel walls.
