Integration of geophysical methods in the study of acid drainage in uranium mining waste
(2018-01-01)
Among the potential environmental impacts in mining activities, acid mine drainage (AMD) is a relevant problem caused by reactive minerals, such as sulfides, due to their exposure to the surface conditions. This is the ...
Identification of Flow Zones Inside and at the Base of a Uranium Mine Tailings Dam Using GeophysicsIdentificación Mediante Geofísica de Zonas de Flujo en el Interior y en el Basamento de una Presa de Colas de una Mina de Uranio
(2021-03-01)
Potential problems related to a tailings dam’s stability are a matter of concern, especially where structural failure might endanger nearby communities and the environment. The Osamu Utsumi mine, located in the State of ...
Analytical ray tracing system: Introducing art, a C-library designed for seismic applications

Structural analysis and geophysical survey for hydrogeological diagnosis in uranium mine, Pocos de Caldas (Brazil)
(Springer, 2019-04-01)
The implementation of open pit mines promotes alterations on geological and hydrogeological processes, mainly on natural streannflow patterns. Drainage system tries to reach its equilibrium due to modification on slope ...
Integration of Geoelectric and Geochemical Data in the Evaluation of Natural Attenuation in a Diesel Contaminated Site in São Manuel (brazil)
(2017-01-01)
Geophysics is a very relevant investigation tool in conjunction with chemical analysis, during the diagnosis and monitoring of contamination in the geological environment. This paper presents the results of DCdefine ...
Decimeter-scale in situ mapping of modern cross-bedded dune deposits using parametric echo sounding : a new method for linking river processes and their deposits
(American Geophysical Union, 2013-08)
Collecting high-resolution data to quantify the sedimentary architecture within contemporary alluvial channels remains one of the outstanding challenges in fluvial sedimentology. Here, we present data collected using a ...
