To introduce various technologies of surveying on the surface and underground
mining situations including distance measurements, leveling, contouring, traversing etc along with descriptions of associated instruments.
Students will get the benefit of fundamentals of surveying knowledge being used for preparation of mine plans. This course gives an opportunity to understand all the techniques of surveying. Students can also get sufficient knowledge on conducting mine surveys using latest instruments and this also provides elementary excursuses using total station, GPS, GIS, data generation, preparation of mine plans in the mining industry.
