In this paper, the results of the finite elements method simulations of loosening of rock by special design ripping head [F. Eichbaum, Schneidend- brechende Gewinnung mit der Schneidscheibe. Experimentell und theoretische Untersuchungen. Gluckauf- Betriebsbucher, Band 22, Verlag Gluckauf GMBH Essen, 1980] have been presented. The influence of friction factor rock and ripping tool on trajectory of loosing of rock has been investigated. It is important to obtain wide range loosing of rock in mining technology. This makes getting a thick excavated material possible and guarantees more energy-saving excavating process.
