Conference Paper
Full-text available
In the world there are a large number of old mining sites, with abandoned tailings dams. They are generally relatively small volume deposits compared to those currently being built. However, with some frequency, some of these abandoned deposits fail, involving liquefaction of the tails, either static or under seismic action, turning the mass of flu...

Filtered tailings is the disposal technology that is most likely to yield an unsaturated state of the tailings. Such state has important benefits. A dam to contain the mine wastes is no longer needed, the risk of polluting seepage is minimized, and liquefaction of tailings is prevented. Filtering also allows most of the water mixed with the tailing...
Conference Paper
Mining manipulates a wide range of soil-like materials. However, mining materials undergo processes that make them different to natural soils. A major fraction of those materials ultimately becomes a waste, which must be stored in a permanent and safe way. On the other hand, an ample range of phenomena, currently being studied in the framework of u...
Conference Paper
This paper presents the results from of a set of in situ and laboratory tests performed in order to characterize the tailings of an abandoned tailings dam of the Castaño Viejo mine, which is located at the eastern foothills of the central Andes mountain range, an arid and seismically active area. The tailings dam has been abandoned since 1964, and...

The filtered tailings technology consists in reducing the water content of tailings ahead of their final disposal and later storing them in stacks with no containment structures. Since the stability of the waste storage facility (WSF) partly relies on the increase of strength due to suction, the unsaturated condition should be always preserved. The...
Conference Paper
Full-text available
Los relaves o colas, conjuntamente con los estériles de mina constituyen los residuos de mayor volumen generados por la actividad minera actual. Las colas están formadas por partículas de roca finamente molida que han sido sometidas al proceso de extracción del mineral y que convencionalmente presentan consistencia de lodo. Para el almacenamiento d...
Conference Paper
Full-text available
En este artículo se presenta la aplicación de una técnica de medición directa de la variación de las dimensiones de una probeta de suelo en ensayos triaxiales basada en procesamiento de imágenes digitales (IP). La aplicación de esta técnica permite medir el cambio volumétrico en muestras no saturadas, sin necesidad de modificar la cámara triaxial....
Conference Paper
Full-text available
The pressure difference attained both sides of the air - water interface (meniscus), at the pores of a non- saturated soil, is known as matric suction and gives rise to attractive forces between the solid grains. Such forces contribute to the effective stress, thus influencing the mechanical behavior of the soil. Matric suction is a fundamental var...
Conference Paper
Full-text available
El filtrado de las colas mineras es una tecnología relativamente nueva, cuya aplicación se va expandiendo gradualmente por el mundo. El objetivo es extraer de las colas, residuo del procesamiento del mineral, una parte del agua que contienen, antes de proceder a su disposición final en un depósito. Las ventajas que esto reporta son múltiples. Por u...
