Non-Newtonian Tailings Dam Break Analysis and Released Volume Estimation Using Site-Specific Parameters

A series of major tailings dam break events have been recorded across the world in recent years. A breach in the impounding structure of a Tailings Storage Facilities (TSF) can lead to catastrophic environmental, social and economic impacts and potentially result in the loss of human lives.

Comparison of Linear and Central Distribution Systems for Thickened Tailings Stacking

One of the key parameters in successful implementation of thickened tailings schemes for tailings management is the achievable tailings beach slope. Study of geomorphology and hydrodynamics of tailings beaches has shown that the achievable beach slope is directly proportional to tailings solids concentration (i.e. rheology) and inversely proportional to discharge flowrate.

Paste and Thickened Tailings Transportation: Design Aspects Overview

Tailings transport is an integrated element in any wet tailings storage facility (TSF). Tailings from the process plant are often thickened to a moderate or relatively high (but still pumpable) solids concentration, depending on several parameters mainly the TSF deposition requirements and strategies, process plant water security status and the dewatering technology utilised.

Integrated Project Risk Management for Residential Recycled-Water Schemes in Australia

In recent years, the Australian water sector has been criticized for in adequate project risk management and over investment in inefﬁcient water services, such as large desalination plants and recycled-water schemes.

Smoothed Particle Hydrodynamics modelling of fresh and salt water dynamics in porous media

Seawater intrusion modelling is often used to assist with groundwater management in coastal areas and islands. Although Smoothed Particle Hydrodynamics (SPH) schemes are able to simulate multi-fluid flows in porous media, they have not been widely tested against experimental observations yet

Exact solutions of the Navier-Stokes equations generalised for ﬂow in porous media

Flow of Newtonian ﬂuids in porous media is often modelled using a generalized version of the full non-linear Navier-Stokes equations that include additional terms describing the resistance to ﬂow due to the porous matrix. Because this formulation is becoming increasingly popular in numerical models, exact solutions are required as a benchmark of numerical codes.

Stochastic modelling of beach profiles including the influence of thickener performance

It is generally well accepted that in the design and operation of thickened tailings storages, ‘better’ thickener performance will improve the beach profile, and thereby enhance the overall performance of the stack.

Expert opinion on risks to the long-term viability of residential recycled water schemes: An Australian study

The water sector needs to make efﬁcient and prudent investment decisions by carefully considering the long-term viability of water infrastructure projects. To support the assessment and planning of residential recycled water schemes in Australia, we have sought to clarify scheme objectives and to further deﬁne the array of critical risks that can impact the long-term viability of schemes.

An Innovative Approach to Determine Particle Size Distribution for Rockfill Material

Particle characterisation like size distribution and shape can greatly affect the mechanical behaviour of granular materials, and is closely related to the economics for engineering projects. For rockfill material in embankment dam construction, the particle size distribution (PSD) is fundamental to the design, quality control and numerical modelling.

SPH modelling of multi-ﬂuid lock-exchange over and within porous media

Multi-ﬂuid ﬂow over and within porous media occurs frequently in nature and plays an important role in engineering applications. The modeling of these ﬂows and validation against experimental or ﬁeld observations have not been largely conducted in literature. An explicit numerical scheme for incompressible ﬂuid using Smoothed Particle Hydrodynamics (EISPH) was employed and solved using two integration algorithms.
