Geotechnical Design of Cut Slopes for Box-Cut “Soto-Norte” Mining Project – Colombia (August, 2017)

The study contains the analyzes and geotechnical recommendations for the formation of the cutting slopes where the Box-Cut of the”Soto-Norte” mining project will be located. Based on reference information from the explorations carried out for the Soto-Norte pre-feasibility study and the support design of the twin plant-mine access tunnels, a geological-geotechnical model was elaborated for the area of ​​interest with which performed stability analysis and the geometry of the cut was established according to the minimum safety factors required by regulations (NSR-10).
Geotechnical design developed for the company Worley Parsons.
