dc.description.abstractTailings are a waste product that must be dealt with during any mining operation. Tailings are most commonly deposited into embankments in layers as the mining project progresses. The prospect of using the tailings as a building material is of interest as it provides a use for what is currently a waste material. This provides a solution to what can be done with the tailings resulting from a mining operation. In order to use the tailings as a building material, its properties must be understood. The dynamic properties of the tailings are critically important for seismic events and are required for design.
dc.description.abstractIt was found that the parameters with the greatest influence on shear wave velocity, Vs, and shear modulus, G, measurements were confining pressure, overconsolidation, method of sample preparation and freezing. The normalized modulus reduction curves demonstrated that the parameters investigated had little to no impact on these curves. A comparison with empirical curves developed for sand and silt soils demonstrated that there is fair agreement between results. The empirical curves considered tended to predict a slightly more linear response than what was measured. The results of RC testing are also compared to centrifuge testing. Centrifuge modeling was conducted to measure the cyclic behavior of tailing impoundments. Higher shear wave velocity values were observed at equal effective stresses for the centrifuge model than from the resonant column tests.
dc.description.abstractIn this study, resonant column testing was conducted to measure dynamic properties of mine tailings. Sample preparation methods and equipment were developed for testing the tailing from a slurry state. A parametric study was conducted to investigate factors affecting the dynamic response of the tailings as measured using the resonant column device. Parameters investigated in this study include confining pressure, consolidation time, effects of layering, effects of freezing samples, and the effects of overconsolidation. Several different sample preparation methods were explored in order to develop a testing procedure for the tailings. These methods include slurry consolidation, dry pluviation, and wet tamping.
