The disciplines of surveying and mining both date back to ancient times. The ancient Greeks not only developed the science of geometry, but they also developed the first surveying tool: the diopter, an astronomical and surveying instrument dating from the third century BCE. The diopter can be regarded as the ancient predecessor of the theodolite.

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the

Most underground coal mines in India employ an exhaust (i.e. 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 at nearly forty stations.
