Available in PDF, EPUB and Kindle. Book excerpt: Minerals and their products play a vital role in humans life after the 19th Century. In 2015, the value of coal, metals, and industrial minerals mined in the United States was over $100 billion according to the report of U.S Geological Survey (USGS). Tailings dams that are usually used to store these wastes encountered several structural failures in the past century. These catastrophes not only affect humans life but also pollute the environment. Recently, an iron tailings dam failure in Brazil on Feb 1, 2019 caused more than 60 deaths and significant economic loss. This study synthesizes the data that were presented in the previous publications in last 40 years along with the coal tailings data that were obtained by the Penn State (PSU) research team. This thesis compared the basic geotechnical properties of different mineral tailings and derived correlations of these properties. The results indicate that fine and coarse coal tailings tend to have lower specific gravity than other minerals. Most of the classifications of fine coal tailings belong to CL and ML. Copper tailings generally have higher hydraulic conductivity than gold tailings. Compared with other mineral tailings, fine coal tailings have the lowest hydraulic conductivity. This study also found that for fine coal tailings the percentage of clay size particles has higher impact on PI than fine content. The percentage of clay size particle and fine content, on the other hand, have very similar impact on LL. A relationship equation between fine content and coefficient of consolidation of fine coal tailings that are classified as SM or ML was derived in this study. The collected database showed that most of the mineral tailings still lack information in both basic properties (i.e. liquid limit and plastic index) and advanced laboratory testing. Even the existing data showed high variability. Compared to the large amount of usage in minerals, the information of mineral tailings is still very limited.

Available in PDF, EPUB and Kindle. Book excerpt: Liquefaction assessment of mine tailings is currently done using empirical correlations that were developed using data mostly collected in natural soils; their applicability to tailings is yet to be proven. In-situ density represented by the state parameter is the key link between liquefaction susceptibility and the Cone Penetration Test (CPT) measurements that are commonly used to characterize tailings. Quantifying the interdependence of gradation, in-situ state parameter, and CPT measurements is a first step towards developing tailings-specific liquefaction assessment methods. The effect of fines content and gradation on the soil properties and the interpretation of the CPT tip resistance was assessed for Base Metal Tailings. Five gradations with fines contents ranging from 0% to 100% were tested. A series of tests were conducted to evaluate the critical state parameters, shear modulus (G), coefficient of lateral earth pressure at rest (K0), particle shape, and mineralogy.

Download or read book Geotechnical Characteristics of Soils and Rocks of India written by Sanjay Kumar Shukla and published by CRC Press. This book was released on 2021-12-31 with total page 872 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents mainly the geotechnical details of geomaterials (soils and rocks) found in all the 36 states and union territories of India. There are 37 chapters in this book. Chapter 1 provides an overview of geomaterials, focusing on their engineering properties as determined based on the project site investigations and laboratory/field tests; this will help readers understand the technical details explained throughout the book, with each chapter dealing with geomaterials of one state/union territory only. Each chapter, contributed by a team of authors, follows a common template with the following sections: introduction, major types of soils and rocks, properties of soils and rocks, use of soils and rocks as construction materials, foundation and other geotechnical structures, other geomaterials, natural hazards, case studies and field tests, geoenvironmental impact on soils and rocks, concluding remarks and references. All the chapters cover highly practical information and technical data for application in ground infrastructure projects, including foundations of structures (buildings, towers, tanks, machines and so on), highway, railway and airport pavements, embankments, retaining structures/walls, dams, reservoirs, canals and ponds, and landfills and tunnels. These details are also highly useful for professionals dealing with mining, oil and gas projects and agricultural and aquacultural engineering projects. Although this book covers the Indian ground characteristics, the information provided can be helpful in some suitable forms to the professionals of other countries having similar ground conditions and applications.

Download or read book Correlations of Soil and Rock Properties in Geotechnical Engineering written by Jay Ameratunga and published by Springer. This book was released on 2015-12-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.
Download or read book Tailings Dam Design Conception des Barrages de St riles Miniers written by Cigb Icold and published by CRC Press. This book was released on 2023-04-03 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tailings are produced from the processing of mineral ores and are commonly stored within embankment dams. The design of the dams requires application of sound engineering principles and an understanding of the properties of the tailings. This Bulletin provides a framework for classifying different types of tailings, ranging from ultra-fine to coarse, based on their geotechnical properties and provides typical geotechnical parameters for the different tailings types. Technologies for dewatering tailings to reduce the risk of storage continue to be developed and the different technologies, from thickening to filtration, and re-application of old technologies are presented to illustrate the options available and, where appropriate, typical in situ properties. This bulletin is directed towards a wide audience of stakeholders: designers, owners, regulators, communities and various organizations and provides a reference for communicating tailings properties and the benefits and limitations of technologies. All mining operations, and thereby tailings operations, are unique. There is no one-solution-fits-all. Tailings dam designs need to account for site-specific conditions, such as climate, physiography, geochemistry, geomorphology, seismology, mining processes, environment, and community setting, with the application of technologies playing an important role in developing safe, sustainable tailings facilities. Les stériles miniers sont produits à partir du traitement des minerais et sont généralement stockés derrière des barrages en remblai. La conception des barrages nécessite l'application de principes d'ingénierie solides et une compréhension des propriétés des résidus. Ce bulletin fournit un cadre pour classer différents types de résidus, allant de l'ultra-fin au grossier, en fonction de leurs propriétés géotechniques et propose des paramètres géotechniques typiques pour les différentes sortes de résidus. Les technologies d'assèchement des résidus pour réduire le risque de stockage continuent à être développées ; les différentes technologies, de l'épaississement à la filtration, en passant par l’application des anciennes technologies, sont présentées pour illustrer les options disponibles et, le cas échéant, les propriétés in situ typiques. Ce bulletin s'adresse à un large public d'intervenants : concepteurs, propriétaires, régulateurs, communautés et organisations diverses et fournit une référence pour communiquer les propriétés des résidus et les avantages et les limites des technologies. Toutes les opérations minières et, par conséquent, les traitements des résidus, sont uniques. Il n'y a pas de solution unique pour tous. La conception des barrages de résidus doit tenir compte des conditions propres au site, telles que le climat, la physiographie, la géochimie, la géomorphologie, la sismologie, les processus miniers, l'environnement et le milieu communautaire, l'application de technologies jouant un rôle important dans le développement de parcs à résidus sûrs et durables.
