For over five years, Itasca Chile SpA (Itasca) has developed and continuously updated, the 3D numerical groundwater flow model for this open pit mine in Chile. The model is primarily used to estimate pore pressure distributions for past, present, and predictive stages of the pit excavation. These are subsequently used for 3D slope stability analysis. With the new and updated model, new predictions for future stages were made, and new mining and drainage plans were evaluated from a hydrogeological point of view.
Isidora Arriagada has a Geologist degree from the Universidad de Concepción, with an M.Sc. degree in hydrogeology and environment from the Technical University of Darmstadt, Germany. She has worked as a hydrogeologist specializing in arid and semi-arid zones and as a consultant in environmental, sustainability, health and safety, legal compliance and engineering. Throughout her career in consulting for the Chilean state and various industries, including mining, she has acquired experience in soil and groundwater studies, hydrogeological modeling, environmental impact studies, design, coordination and execution of field campaigns and remediation projects.
