Consolidation behavior of various types of slurry tailings co-disposed with waste rock inclusions: a numerical study

The co-disposition of mine tailings and waste rock in storage facilities (TSFs) could contribute to increase the consolidation rate decrease long-term settlement tailings. Non-linear change properties during filling process interaction between inclusion (WRI) are critical mechanical analysis but can, however, be complicated simulate. question net volume gains or losses was also raised. In this study, fully coupled which considered continuous variation hydraulic conductivity stiffness were performed assess evolution various types presence WRI. Effects ratio over WRI on investigated. Finally, effect several practical aspects such as rates, instantaneous assumption considered. Results indicated that by 3.3 times zone influence varied for each Using updated showed significant differences compared models with constant values. application can reduce available volumetric due without estimated explicitly. Equations predicting changes accordingly proposed. effects more pronounced rate. had little simulated consolidation.
