Underground surveying is quite different from surveying on the surface. In tunnelling or mining operations it may be hot, wet, dark, cramped, dusty, dirty and dangerous, and usually most of these. The essential problem in underground surveying is that of orientating the underground surveys to the surface surveys, the procedure involved being ...
Furthermore, mine surveying provides challenges in everyday tasks while also providing an enjoyable, rewarding career. There are also different types of mine surveyors, with options to work underground, open cut or both, and in the coal industry or various mineral mining industries.
Underground Mining Surveys. We can provide underground mining survey services for ongoing mining operations, but also for historic workings that may be re-opened or are in close but unknown proximity to new workings. Our expert underground team can also help avoid exploration boreholes striking extant underground workings.
Jan 12, 2018 Surveying in the mining industry, both in open-pit and underground mines, often goes hand in hand with terrestrial laser scanning TLS, which is deployed to verify the spatial changes of mining works. Thanks to its high point density and high accuracy, TLS is a very suitable surveying technique for monitoring movements and deformations.
