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 termed a correlation .
infrastructure for massmining. First underground production is planned for 2021. The need to include the survey discipline from the outset of the project has risen as key to the successful delivery of a quality project. Survey errors and delays can have significant safety, schedule and cost impacts. Survey
Surveying in the mining industry, both in openpit 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.
In surveying, a gyrotheodolite (also: surveying gyro) is an instrument composed of a gyroscope mounted to a is used to determine the orientation of true is the main instrument for orientation in mine surveying and in tunnel engineering, where astronomical star sights are not visible and GPS does not work.
Most underground coal mines in India employ an exhaust ( negative pressure) ventilation system. This project deals with the pressure and air quantity survey of an underground coal mine ventilation system at Nandira colliery, Talcher. The survey work has been carried out with the help of latest instruments .

Mining Surveyors are responsible for the calculated mathematical measurements that are involved in the safe creation and maintenance of mining sites. Topological measurements obtained aboveground and underground are used by the surveyor to produce detailed mappings of mining locations. The skill set required for a Mining Surveyor includes:
What is the role of a mine surveyor? Mine surveyors are involved in the accurate measurement and recording of mine workings. They are critical to the design, planning and safety of surface and underground mining activities, which must be accurately represented on mine plans.
Mine surveying is a composite science that is closely related to many scientific disciplines: mathematics, engineering, physics, astronomical geodesy, geology and mineralogy, geological exploration, the technology of exploitation of deposits, and construction. Mine surveying is an inseparable part of all stages of mining operations.
