Weak rocks encountered in open pit mines cover a wide variety of materials, with properties ranging between soil and rock. As such, they can provide a significant challenge for the slope designer. For these materials, the mass strength can be the primary control in the design of the pit slopes, although structures can also play an important role. Because of the typically weak nature of the materials, groundwater and surface water can also have a controlling influence on stability.
Guidelines for Open Pit Slope Design in Weak Rocks is a companion to Guidelines for Open Pit Slope Design, which was published in 2009 and dealt primarily with strong rocks. Both books were commissioned under the Large Open Pit (LOP) project, which is sponsored by major mining companies. These books provide summaries of the current state of practice for the design, implementation and assessment of slopes in open pits, with a view to meeting the requirements of safety, as well as the recovery of anticipated ore reserves.
This book, which follows the general cycle of the slope design process for open pits, contains 12 chapters. These chapters were compiled and written by industry experts and contain a large number of case histories. The initial chapters address field data collection, the critical aspects of determining the strength of weak rocks, the role of groundwater in weak rock slope stability and slope design considerations, which can differ somewhat from those applied to strong rock. The subsequent chapters address the principal weak rock types that are encountered in open pit mines, including cemented colluvial sediments, weak sedimentary mudstone rocks, soft coals and chalk, weak limestone, saprolite, soft iron ores and other leached rocks, and hydrothermally altered rocks. A final chapter deals with design implementation aspects, including mine planning, design implementation, monitoring, surface water control and closure of weak rock slopes.
Key Features:
Illustration of the best practice in modern open pit mines
State of the art approaches for challenging designs
Use of numerous case histories written by large-open pit operators to illustrate state of practice
Individual chapters/sections written by leaders in the industry
As with the other books in this series, Guidelines for Open Pit Slope Design in Weak Rocks provides guidance to practitioners involved in the design and implementation of open pit slopes, particularly geotechnical engineers, mining engineers, geologists and other personnel working at operating mines.

Описание: This book described the current status and possible future changes of the thermokarst (thaw) lakes of western Siberia as dominant forms of landscape and regulators of greenhouse gas exchange within the atmosphere. Thawing permafrost and resulting microbial decomposition of previously frozen organic carbon is one of the most significant terrestrial ecosystem positive feedbacks to a warming climate. Ongoing processes of the permafrost thawing in Western Siberia are likely to increase the surface of water bodies via forming so-called thermokarst lakes, mobilising the organic carbon (OC) from the soil pool to the rivers and, finally, to the ocean, and thus modifying the fluxes of methane (CH4) and CO2 to the atmosphere. Despite their tremendous importance for green house gazes regulation and hydrological regime control, very little is known about hydrochemistry of western Siberia thaw lakes. This book assesses the variation of major and trace elements (TE) and organic carbon (OC) concentration along the chronosequence of lake development and the latitude profile of variable permafrost abundance; characterises the colloidal status of TE and distinguishes between the relative proportion of organic and organo-mineral colloids; describes the particularity of microbiological composition of thermokarst lake waters and production/mineralisation processes in the water column; and presents the perspective of water chemical composition evolution under the climate change scenario. Each of these aforementioned objectives present a scientific challenge given mainly the paucity of existing information on these important but still very poorly studied ecosystems. Taken together, understanding of these issues and identification and quantification of controlling environmental parameters should produce conceptually new knowledge of biogeochemical processes operating within the Western Siberia Plain with the possibility of extrapolation of generated knowledge to much larger territories of arctic and subarctic permafrost-affected areas.

This text details the plant-assisted remediation method, “phytoremediation”, which involves the interaction of plant roots and associated rhizospheric microorganisms for the remediation of soil contaminated with high levels of metals, metalloids, fuel and oil hydrocarbons, nano particles, pesticides, solvents, organic compounds and various other contaminants. Many chapters highlight and compare the efficiency and economic advantages of phytoremediation and nano-phytoremediation to currently practiced soil and water treatment practices.
Volume 6 of Phytoremediation: Management of Environmental Contaminants continues the series. Taken together, the six volumes provide a broad–based global synopsis of the current applications of phytoremediation using plants and the microbial communities associated with their roots to decontaminate terrestrial and aquatic ecosystems.

Описание: Soil biochemistry is the reference book available that covers the essentials of the topic plus provides information on the latest technological advances that represent the cutting edge of the science .soil plays a crucial role on numerous environmental processes. They interact with the air above them, and the biological activity in them. They supply nutrient to plants and filter our wastes. The book is a concise and authoritative introduction to the field of environmental soil biochemistry that is very suitable for a one semester course. The second edition is replete with crisp graphics and real world examples that lay out the foundations of soil biochemistry, while providing a firm basis for illustrating the emergence in our field of cutting-edge techniques in molecular spectroscopy and kinetics. Soil support life. Soils contain air, water, and minerals. Not surprisingly, soil biochemistry involves many environmental disciplines, such as atmospheric chemistry, aquatic chemistry, interface chemistry, inorganic chemistry, organic chemistry, biochemistry and mineralogy. The chemistry principles in this book are presented in a sequential manner, and many of them are covered in great depth. Often, the concepts in soil biochemistry cannot really be well understood unless you also understand them from a mathematical point of view. Sometimes, however, the mathematics behind the soil biochemistry principles can be a bit overwhelming.

Описание: As the world`s population continues to grow, it is vital to maintain and increase agricultural productivity, even in the midst of changing weather patterns. Focusing on arid regions, this book details soil classification inventories from a number of countries.
Structured in the form of a dichotomous key, comparable to those widely used in botany, the mineral key provides an efficient and systematic approach to identifying rock-forming minerals in thin-section. This unique approach covers 150+ of the most commonly encountered rock-forming minerals, plus a few rarer but noteworthy ones. Illustrated in full colour, with 330+ high quality mineral photomicrographs from a worldwide collection of igneous, metamorphic, and sedimentary rocks, it also provides a comprehensive atlas of rock-forming minerals in thin-section.
Commencing with a brief introduction to mineral systems, and the properties of minerals in plane-polarised and cross-polarised light, the mineral key also includes line drawings, tables of mineral properties and an interference colour chart, to further aid mineral identification. To minimise the chance of misidentification, and enable less experienced petrologists to use the key with confidence, the key has been arranged to prioritise those properties that are most easily recognised.
Designed for simplicity and ease of use, it is primarily aimed at undergraduate and postgraduate students of mineralogy and petrology, but should also provide a valuable source of reference for all practising geologists dealing with rock thin sections and their interpretation.
