Tailings (mining waste) disposal is a significant consideration for the mining industry. It is of value for mine operators and tailings engineers to be able to predict the slope of the deposit (commonly referred to as a tailings beach), which forms from the hydraulic discharge of tailings slurry. In this thesis, existing methods for the prediction of tailings beach slopes are investigated. These methods are validated against relevant industrial and experimental data. Two separate phases of experimental work have taken place in an effort to investigate tailings deposition behaviour, one at mine sites and the other in a laboratory on a small scale. The methodology and results of this experimental work are presented here. Three new tailings beach slope prediction models are presented; a simple empirical model enabling quick approximate predictions; an a priori tailings beach slope prediction model based on existing theories of open channel flow, sediment transport and rheology; and a new semi-empirical model that shares some of the theoretical aspects of the a priori model but offers better predictions due to its empirical calibration to the experimental data.

Tailings beach slope is a key parameter in design of tailings storage facilities. It influences the deposition plan, facility footprint, storage capacity and staging

Tailings beach slope is a key parameter in design of tailings storage facilities. It influences the deposition plan, facility footprint, storage capacity and staging. This paper presents a method for applying existing analytical models to flume test and other rheological test results to allow the prediction of field-scale tailings beach slopes. Several authors have proposed analytical and testing methods for predicting tailings beach profiles. Flume tests are often used during design to provide an indication of how the tailings may beach.

The prediction of tailings beach slope is important to reduce operational risk and optimise the design of a storage facility. Today this is even more important as the trend in mine throughput and storage area footprints continue to increase due to advancements in mechanisation and processing technology. For this reason, beach slope prediction methods have become a focus of attention over the recent years to try and improve this important design parameter that greatly influences the design and operation of a tailings storage facility.

The concept of thickened tailings stacking as a means of surface disposal of mine tailings, first introduced by Eli .

The concept of thickened tailings stacking as a means of surface disposal of mine tailings, first introduced by Eli Robinsky in the mid 1970s as an alternative to storing tailings in impoundments behind embankments, has come a long way. The authors have identified a number of issues that confront the technique – beach slope prediction, pipeline design, seepage to groundwater, seismic stability and rehabilitation – and discuss each in turn.

A Philosophy of Walking book. Indeed, one of the most pervasive themes of this book is how little Gros respects social pleasures or the intellectual work done in scholarly communities; this book is frankly anti-intellectual and anti-populist in many places.

book means that while there is a strong overall structure, each chapter can be read, up to a point, independently. Thus, a reader interested in, say, personal identity, could read Chapter 28 in Part V (Philosophy of mind) without reading the whole of that part, or indeed the whole of the book.
