Item Geophysical-geotechnical investigation of an old tailings dam from a mine in the Peruvian highland.(2020) Barriga Paria, Christ Jesus; Barriga Gamarra, Jorge Pantaleon; Pereira, Eleonardo LucasA 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 poledipole 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.
