[en] The Pribram uranium deposit belongs among the hydrothermal vein type deposits and is located in solid rock formations. Indirect concentration reducing processes over the past twenty years have in a number of deposits resulted in the deformation of the surface. A brief analysis is presented of the problem of underground cavities and reactions of the massif and the mechanism is discussed of indirect concentration reducing processes and the usual procedures given in the calculation of the magnitude of surface deformations. On the basis of experiences and own geomechanical surveys in the Pribram deposit the method was developed of computing the effect of mining on the surface. The procedure of the computation consists in the distribution of vein nodes into groups of veins, the preparation and processing of input data, identification of coefficients of rock softening and actual computation. The computation proceeds in four stages; the computation of the volume deficit, the computation of the volume reduction, the computation of the size and range of deformations; the computation of this surface deformation will serve as the basis for physical planning after the mine has been excavated.
