Open Pit Mine Waste Dump Area Design based on Stability Principles

The main purpose of this study is to design waste dump area for an open pit copper mine owned by Asya Maden Inc. located in Hanonu, Kastamonu. Design studies can be carried out based on slope stability principles as per the design works of open pit bench and overall slope angle. Therefore, geotechnical properties of dump material as well as ground must be primarily determined. Hydrogeology as well as seismicity which have important effect on the stability should be also part of stability works. The values of geotechnical parameters for dump material controlled the stability of dump site determined from the back analysis method from different designs, because of the unavailability of dump material since dumping is not initiated at present. This application iterated for the other designs having different overall slope angles. As a result of the stability analyses based on limit equilibrium methods, the values of geotechnical parameters making the design stabile are determined. After this stage, relations among geotechnical properties and overall slope angle of the dump site as well as dump site capacity are presented.
