Abstract: Beidou satellite navigation system provides a new technical means for mine surveying.The feasibility and accuracy of the Beidou satellite navigation system used in mining surveying is discussed by using theoretical analysis and experimental methods.And the development and positioning principles of Beidou satellite navigation system are introduced.The accuracy relations between Beidou satellite navigation system and GPS，RTK are figured out by analyzing the measured data.The conclusion is that the accuracy of Beidou RTK has reached the same level as that of GPS RTK.Beidou satellite navigation system applied into mine surveying can improve the efficiency and accuracy of mine surveying，and also is conductive for the promotion of sustainable development in the mining area.Finally，issues that should be paid attention to in application of Beidou RTK in mine surveying are analyzed.

Key words: Beidou satellite navigation system, RTK, Mine surveying, Accuracy analysis
