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 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.
