The dynamics deformations of the Bear Cave rock mass

The paper presents the geodetic measurement results of vertical displacements of benchmarks inside and outside the Bear Cave in the period 1984 - 1999. The results of benchmark displacements and the comparative analysis results of measured height differences between benchmarks in relation to their position at the detected and expected tectonic faults are presented. The geodetic results have been analysed in relation to stability of rock masses after finishing of excavation in neighbouring stone mine.
