The course does not provide prerequisites with other courses of the Master's Degree Program. However, knowledge of the geological concepts acquired in the Degree in Geological Sciences is required. The frequency of the course in Structural Geology is recommended.

Ability to describe quantitatively the physical-mechanical properties of rocks, discontinuities and rock masses.
Competence in field geomechanical surveys and geomechanical data processing in order to create thematic maps.
Knowledge of the methods of investigation and classification of rock masses.
Application of geomechanics to practical problems (choice and determination of parameters).
