Construction of a tunnel, its maintenance or reconstruction be it for coal or other mines, railways, dams and metro lines is a quite challenging task. The risks of soil erosion/crack development and alignment from two different ends are some of the important factors that are foremost on the minds of planners. This is the scenario where the 3D laser scanners play an important role by providing highly accurate scans to the planners to mitigate technological support to perform this difficult task of tunnel construction. Safety of man and machines in tunneling and mining processes is one of the most important factors. Occurrences or reoccurrence of any minor or major accidents at such prevented at all costs. As any such incident/s not only create delays but also impacts financially.
The 3D laser scanning technology is a boon in this regards and makes the tunnelling and mining work much more secure by mitigating any likely safety threats. Any fissures or cracks can be easily identified once the scans at various stages are compared with the previous scan results to identify any upcoming threats/concerns. The 3D laser scans immediately point out any kind of change in local rock strata or its variation. The 3D laser scanners provide highly accurate 3D documentation in only few minutes for geological comparing and structural assessment resulting in providing perfect solutions for mining tasks and mitigate security threats at its early stage.
The 3D laser scanners can be used in inverted position to measure any surface virtually even in inaccessible and complex situations and confined spaces which make it a perfect solution for tunneling and mining application.
