MINERÍA la mejor puerta de acceso al sector minero EDICIÓN 580 / ENERO 2026 62 Geología Abstract Remining old tailings deposits presents significant geotechnical challenges, mainly due to the heterogeneity of tailings and the lack of comprehensive construction records. Thorough geotechnical characterization is essential and should include integrated field and laboratory campaigns—such as CPTU tests, electrical resistivity, and triaxial testing—to inform extraction strategies and enable zoning based on the physical, chemical, and hydraulic behavior of the tailings. Old tailings typically exhibit high degrees of saturation and contractive DESAFÍOS GEOTÉCNICOS EN LA REMOCIÓN DE DEPÓSITOS DE RELAVES ANTIGUOS
