Which is better: mobile tunnel mapping or static tunnel mapping?
Using transportable 3D scanners to perform mobile tunnel mapping in underground mines has several advantages over using static scanners to perform this function, but by far, the factor that makes them the most valuable is their speed.
A scanner that is purpose-built for mobile tunnel mapping can be mounted on an RTV or other maneuverable mine vehicle, and then used to perform tunnel mapping while the vehicle is being driven through the mine at normal operating speed.
By comparison, static scanners are generally mounted on a tripod. Once they have scanned the part of the tunnel and surroundings that is within their range, these static scanners are usually removed from the tripod and then moved to the next location, where they have to be re-mounted on the tripod.
This activity can be very time-consuming, and often more time is spent on assembly, disassembly and moving of the static scanner and tripod than is actually spent on the core function of scanning.
Because there is so much movement and complexity related to using static scanners, their use can be quite labour-intensive and may even require special training for staff involved.
Mobile mine scanners, on the other hand, can be operated by a single person, usually an existing member of staff like a mine engineer or surveyor, with only minimal instruction.
Because they can scan on the move and are so easy to operate, 3D mobile mine scanners like the uGPS Rapid Mapper™ are the ideal solution for all the tunnel mapping requirements within a typical underground mine. Mobile tunnel mapping is definitely the way to go.
