The subject of the research in this paper are correlated relations between seismic and geomechanical features of the medium. Special interest for analysis is made on carbonate rock complexes covering an extensive area in the Republic of Macedonia, especially in the western part. Terrain seismic investigations are made on specific locations defining Vp and Vs velocities. On the same locations are made geomechanical and engineering - geological explorations. In the paper is presented dependence between Vp and Vs velocities and geomechanical parameters of the medium: Е - Young’s modulus of elasticity, G - shearing modulus and ν - Poisson coefficient. Calculated are dependence of these paramform Vp and Vs velocities, or an attempt is made to assess the geomechanical parameters through analysis of seismic speeds. Qualitative assessment is made on the degree of dependence of seismic velocities Vp and Vs with RQD, RMR and Q parameters of carbonate massifs, as well as with φ - angle of internal friction and с - cohesion of material.

Keywords: correlation, seismic velocities, geomechanical parameters, assessment
