The studies of the rock mass movements on considerable depths can be carried out based on the network of geodetic points, present in the mining excavations. Such a network is very unfavourable in a sense of geometry, because it is, in a large part, built of open traverses. Often the only way to raise the accuracy parameters of such a network is making the azimuth measurements on selected sides of the network with the use of gyrotheodolites. Applying the carried out gyroscopic observations in the levelling of the network gives base to select the regions, where the rock mass is not stable and the dislocation of stabilized there geodetic points occurred. In the article the stability of selected underground geodetic control line was assessed and basic rules of using gyroscopic instruments, the way of determining the accuracy of the measurement and the control of the correctness of their work were defined.
