Surveying in the Mining Sector | GIM InternationalJan 12, 2018 · Mine Surveying Today. Mining surveying can be summarised as 'the digging of mine shafts and galleries and the calculation of volume of rock', although it entails much more than this in practice. Geometric constraints – vertical shafts and narrow passages – demand the use of specific survey techniques.
