Abstract:

Coordinate and bearing transferring into undergrounds is the important task of mine surveying. Depending on the shafts system, the orientation can be carried out by different ways. The orientation through two shafts is one of the best methods. It is necessary to analyse the accuracy and forecast the technical standards for every measurement in surface and underground as well. The paper deals with the way of errors analysis of the orientation through two shafts. The results should be used in Vietnamese mine surveying practice
