Advanced monitoring of tailings dam performance using seismic noise and stress models

چکیده
Abstract Tailings dams retain the waste by-products of mining operations and are among world’s largest engineered structures. Recent tailings dam failures highlight important gaps in current monitoring methods. Here we demonstrate how ambient noise interferometry can be applied to monitor performance at an active using a geophone array. Seismic velocity changes less than 1% correlate strongly with water level adjacent pond. We implement power-law relationship between effective stress shear wave velocity, pond recordings profiles obtained from cone penetration tests model velocities. The resulting one-dimensional shows good agreement seismic changes. As provides direct measure soil stiffness used infer numerous other geotechnical design parameters, this method advances understanding over time.

Monitoring Volcanoes using Seismic Noise Correlations*
In this paper, we summarize some recent results of measurements of temporal changes of active volcanoes using seismic noise cross-correlations. We first present a novel approach to estimate volcano interior temporal seismic velocity changes. The proposed method allows to measure very small velocity changes (≈ 0.1%) with a time resolution as small as one day. The application of that method to Pi...
متن کاملFloods from tailings dam failures.
This paper compiles the available information on historic tailings dam failures with the purpose to establish simple correlations between tailings ponds geometric parameters (e.g., dam height, tailings volume) and the hydraulic characteristics of floods resulting from released tailings. Following the collapse of a mining waste dam, only a part of tailings and polluted water stored at the dam is...

Earth-fill dams stability in steady state seepage condition is very important, especially during earthquakes. Numerical software analyses require accurate and realistic modeling of construction stages. Since earth-fill dams are constructed in different layers, so these conditions should be considered in software modeling to achieve a reasonable design. In this study, an earth-fill dam is modele...
