Sažetak
In most cases, once the slope stability analyses of future quarry cuts are completed and mine management accepts results and designs, the geotechnical consulting is outsourced from further activities such as excavation plan design, excavation and mining and necessary activities on engineering geological mapping of excavated cuts, geotechnical supervising and active geotechnical design are not carrying out. This approach often leads to occurrences of local or global instabilities of quarry cuts. This paper presents a case study of global instability of open pit slopes in the Torine open pit that is situated in the Pannonian Basin, near the city of Gradac Našički in Croatia. Exploitation zone of basalt rock mass is underlain by chlorite schist rock mass. Sliding of basalt rock mass was developed along the slip surface at the geological contact with chlorite schist. Exploitation has been continuing even after sliding occurrence, without any previous remediation. On the basis of engineering geological mapping results, three separate landslide phenomena were determined. Despite its fact, the exploitation in the Torine open pit is continued till nowadays.
