Özet

Landslides are one of the most common hazards in open pit mines. The occurrence of a landslide affects both the safety and economy of the pits. By understanding the movement mechanism of the slopes, preventative safety studies can be undertaken. The determination of the orientation of a landslide is the most important step to understand the movement mechanism in open pit mines. The dip and the dip direction of a slope give significant information about the orientation of a landslide, traditionally measured by compass. This study presents an approach to determine the landslide movement orientation and slope deformation rate by using a 3D terrestrial laser scanner. A landslide on the north-east of the Simav open pit where is located at the west region of Turkey, known as the Kucuk Hill landslide, was examined as a case study. The orientation of the slopes was found and contour graphs were drawn. Then, stereographic projection results showed the orientation of the landslide. On the other hand, a monitoring scenario was revealed and the deformations on the pit benches were determined.
