Geophysical-Geotechnical Investigation of an Old Tailings Dam from a Mine in the Peruvian Highland
Bibliographic record
Abstract
A tailings dam is designed to operate under steady state flow conditions. An unconventional flow regime can be a threat to the integrity of its structure. In this sense, a correct geological-geotechnical investigation becomes a constant necessity, either by conventional mechanisms or even with the use of geophysical techniques. Geophysical methods play an important role in a geological description, in the mapping of flows and in monitoring changes over time. This paper presents the results of an investigation of the pole- dipole arrangements in Peru in lead, zinc, silver, and copper polymetallic ore mine with a height of 4,700 meters with the principal goal of to know the thickness of the anthropic sediment of the tailings deposit. The mine has an old tailings dam, where the electrical method was used by tomography to delineate possible areas of infiltration, to allow the mine closure plan required by the competent authorities, aiming, in the long term, the lowest risk to safety and health of the population, in addition to mitigating the associated environmental impacts. Keywords: dam, tailings, electrical tomography, mining geophysics. Investigação Geofísica-Geotécnica de uma Antiga Barragem de Rejeitos de uma Mina na Serra Peruana RESUMO. Uma barragem de rejeitos é projetada para operar sob condições de fluxo em estado estacionário. Um regime de fluxo não convencional pode ser uma ameaça à integridade de sua estrutura. Nesse sentido, uma correta investigação geológico-geotécnica torna- se uma necessidade constante, seja por mecanismos convencionais ou mesmo com o uso de técnicas geofísicas. Os métodos geofísicos desempenham um papel importante em uma descrição geológica, no mapeamento de fluxos e no monitoramento de mudanças ao longo do tempo. Este artigo apresenta os resultados de uma investigação dos arranjos polo-dipolo no Peru em uma mina de minério polimetálico de chumbo, zinco, prata e cobre, com uma altura de 4.700 metros, com o objetivo principal de conhecer a espessura do sedimento antrópico de uma antiga barragem de rejeitos. Esta barragem, onde o método elétrico foi utilizado pela tomografia elétrica para delinear possíveis áreas de infiltração, para permitir o plano de fechamento da mina exigido pelas autoridades competentes, visando, a longo prazo, o menor risco à segurança e saúde da população, além de mitigar os impactos ambientais associados. Palavras-chave: barragem, rejeitos, tomografia elétrica, geofísica de mineração.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
