This paper will address critical aspects for consideration when characterizing parameters related to geology, structural geology, hydrogeology and rock mass for definition of geotechnical domains for slope design. The types of deposits that will be presented: general porphyry rock masses (i.e. Read more... about Approach to Geotechnical Characterization and Slope Design Data Acquisition Programs in Different Deposit Types

El Teniente Division of CODELCO is conducting a pre-feasibility engineering evaluation of Rajo Sur project in Chile. This project involves construction of an open pit to mine a copper deposit near the southern border of the caving subsidence crater high in the mountains above El Teniente mine.

Kinross Gold Corporation has several porphyry/epithermal gold properties in Maricunga gold belt in northern Chile. The Maricunga site comprises the operating Verde pit and the Pancho deposit, currently under development. Currently active operations are all open pits mines of a medium scale, and Read more... about Slope Design for Maricunga Mine in Chile

The Cuajone porphyry copper deposit is located on the western slopes of Cordillera Occidental, the southern Andes of Peru. The current pit measures about 2.5 km east–west, 3.0 km north–south, and at the end of 2012, had a maximum depth of 950 m. Mining by open pit methods commenced in 1976 and Read more... about Slope Design at Cuajone Pit, Peru

Probabilistic methods combined with risk assessment are a better way to assess slope design in open pit mines compared to deterministic methods. These methods are suitable for use on evaluation of risk or when there is uncertainty in the input parameters.
