Geotechnical Risk Analysis For The Closure Alternatives Of The Chuquicamata Open Pit
L‐F Contreras, E Hormazabal, R Ledezma, M Arellano

The development of the geotechnical risk model for the Chuquicamata mine started in 2005 and included the safety and economic impacts of slope failures at different scales (Tapia et al. 2007; Steffen et al. 2008).

Influence Of Hoek-Brown Linearization And Input Cross-Correlation In Slope Probability Of Failure Calculation
Cristóbal Valderrama, Felipe Sanz and Esteban Hormazábal

When Hoek-Brown failure-criterion (H-B) is selected, their parameters are determined as the ones that better fit data; therefore, depends on the method of fitting, the experimental error and statistical sufficiency of data.

Managing And Validating Limited Borehole Geotechnical Information For Rock Mass Characterization Purposes
Andrés Huaman, Joel Cabrera, Antonio Samaniego

The assessment of rock mass blockiness is fundamental for any geotechnical study, managing and validating geotechnical information is then critical for rock mass characterization purposes, especially when the borehole information is limited or the available cores are disturbed.
