Namen pričujočega prispevka je ugotoviti pogoje pri katerih pride do loma kamnitega kosa in s tem do zmanjšanja njegove mase in spremembe odbojnih karakteristik. Lom kamnitega kosa je odvisen od strukture in kvalitete kamnine, ki sta izraženi z modulom elastičnosti in enoosno tlačno trdnostjo kamnine.

Sekundarni naslov: ǂThe ǂimpact of mechanical properties of rock to the collision of rock piece
Sekundarni povzetek: The paper presents the analytical solution of the rock piece motion considering influences of geometrical and mechanical characteristics of rock mass on the arbitrary slope. The main objective of the paper is to determine the motion of the rock piece considering possibility of rock piece failure due to collision. Brief description of the analytical solution of the rock piece motion on a steep slope is given. The laboratory tests were performed to determine uniaxial compressive strength and elastic properties of the considered rock mass. Further, velocities that cause rock piece failure were determined. These maximum velocities indirectly belong to certain mass of rock piece and can be lower than velocities calculated in rock-fall analysis for certain slope geometry. Consequently, the energy magnitude is limited, because at certain velocity and mass of rock piece bigger pieces crash at collision.
