What is the difference between mine surveying and other surveying and mapping industry compared.

Mine surveying and other compared to the biggest difference or to go down the well, right, do is pit survey, to work in the well. There is no difference between the other, the mapping method is also measured with a total station, these are basically the same. Control points are usually made at the top of the roadway. Of course, there are also measurements on the ground, such as the control of the entire mine. Underground measurement is of course higher than the general measurement of wages, generally how much money a meter. This depends on what the market is in different places. The disadvantage is that there may be safety issues worth noting ah If my answer can help you, but also please trouble to adopt it
