...M. E. Karim; M. M. Rahman; M. R. Karim; H. B. K. Nguyen; A. B. Fourie; D. Reid Tailings dams are often constructed using tailings themselves. Every year, 2–5 catastrophic tailings dam failures are reported globally, highlighting the need for improved understanding of tailings behaviour. This study...

...David Solans; Stavroula Kontoe; Lidija Zdravkovic This article examines the construction, operation and seismic performance of the El Torito tailings storage facility, Chile, under the 2015 Illapel earthquake. A two-dimensional plane strain finite-element model, employing coupled hydro-mechanical...

...Riccardo Fanni; David Reid; Andy Fourie A laboratory study was carried out on a sandy silt gold tailings to investigate the effect of the Lode angle (θ) on the critical state line (CSL) in the compression (e–p′) and effective stress (q–p′) planes, and to study...

...Ali Lashkari; Saeed Khademian; Ahmad Feilinejad; Piltan Tabatabaie Shourijeh; Aliyeh Afzali-Nejad To investigate the potential for flow instability in the interfaces between iron ore tailings and woven geotextile (GTX), direct simple shear (DSS) tests covering a wide domain of initial states...

...Abouzar Sadrekarimi; Grytan Sarkar Lateral stress relief and effective stress reduction have been recognised as the culprits in flow failures of several mine tailings dams. This research examines the instability of coarse oil sand tailings (CSTs) subjected to such a stress path through a series...

...Yanzhi Wang; Thanh Vo; Adrian R. Russell The potential for static liquefaction of tailings is a major focus in the design and operation of tailings storage facilities. This research models the behaviour of unsaturated tailings, with a variety of degrees of saturation, addressing the propensity...

...Alexia Cindy Wagner; João Vítor de Azambuja Carvalho; Hugo Carlos Scheuermann Filho; Nilo Cesar Consoli The inherent variability of tailings is the main challenge in compacted filtered tailings stacks (CFTS) operation. Despite the advances in dewatering technologies, the filtration efficiency...

...G. D. Lu; A. P. S. Selvadurai; M. A. Meguid Recycling cement-amended tailings into subsurface cavities has delivered competitive socioeconomic revenue for underground mining. However, recent instances of anomalous thermal pressure in consolidating backfill have raised growing concerns over...

...Abigail Cartwright; Matthew Coop; Li Wei; Andy Fourie Tailings have previously been identified as having the types of mixed mineralogies and gradings that can make them susceptible to having non-unique critical states and normally compressed states in laboratory element tests. This paper addresses...

...Rodrigo Zorzal Velten; Nilo Cesar Consoli; Hugo Carlos Scheuermann Filho; Alexia Cindy Wagner; Fernando Schnaid; João Paulo Rodrigues Da Costa Tailings dams constructed using the upstream method are generally less stable, because of its operational and constructive approach; this presents increased...

...Maral Bayaraa; Brian Sheil; Cristian Rossi In this paper, ground deformation measurements from synthetic aperture radar interferometry (InSAR) and ground-based prism monitoring are compared to finite-element (FE) simulation results for a recent tailings dam collapse. The InSAR monitoring...

...Adrian R. Russell; Thanh Vo; Juan Ayala; Yanzhi Wang; David Reid; Andy B. Fourie Laboratory-controlled cone penetration test results for two silty tailings in a variety of saturated and unsaturated states, obtained using two calibration chambers, are presented then interpreted using a state...

...Amirreza Fotovvat; Abouzar Sadrekarimi; Michael Etezad The drained instability of two gold mine tailings under lateral stress relief is investigated in this study. Constant deviator stress (CDS) unloading tests were performed using a triaxial apparatus to examine instability imposed by unloading...

...J. BEDIN; F. SCHNAID; A.V. DA FONSECA; L.DE M. COSTA FILHO The results from a laboratory testing programme designed to evaluate the behaviour of gold tailings are presented, and interpreted in the critical state framework. Drained and undrained triaxial tests sheared under monotonic loading allowed...
