Guidelines for Open Pit Slope Design is a comprehensive account of the open pit slope design process. Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on the stability of rock slopes in open pit mines, this book provides an up-to-date compendium of knowledge of the slope design processes that should be followed and the tools that are available to aid slope design practitioners. This book links innovative mining geomechanics research into the strength of closely jointed rock masses with the most recent advances in numerical modelling, creating more effective ways for predicting the reliability of rock slopes in open pit mines. It sets out the key elements of slope design, the required levels of effort and the acceptance criteria that are needed to satisfy best practice with respect to pit slope investigation, design, implementation and performance monitoring. This book will assist open pit mine slope design practitioners, including engineering geologists, geotechnical engineers, mining engineers and civil engineers and mine managers, in meeting stakeholder requirements for pit slopes that are stable, in regards to safety, ore recovery and financial return, for the required life of the mine.

Beginning with a sustained analysis of Seneca's theory of monarchy in the treatise De clementia, in this text Peter Stacey traces the formative impact of ancient Roman political philosophy upon medieval and Renaissance thinking about princely government on the Italian peninsula from the time of Frederick II to the early modern period. Roman Monarchy and the Renaissance Prince offers a systematic reconstruction of the pre-humanist and humanist history of the genre of political reflection known as the mirror-for-princes tradition - a tradition which, as Stacey shows, is indebted to Seneca's speculum above all other classical accounts of the virtuous prince - and culminates with a comprehensive and controversial reading of the greatest work of renaissance political theory, Machiavelli's The Prince. Peter Stacey brings to light a story which has been lost from view in recent accounts of the Renaissance debt to classical antiquity, providing a radically revisionist account of the history of the Renaissance prince.

It sets out the key elements of slope design, the required levels of effort and the acceptance criteria that are needed to satisfy best practice with respect to pit slope investigation, design, implementation and performance monitoring.Guidelines for Open Pit Slope Design comprises 14 chapters that directly follow the life of mine sequence from project commencement through to closure. It includes: information on gathering all of the field data that is required to create a 3D model of the geotechnical conditions at a mine site; how data is collated and used to design the walls of the open pit; how the design is implemented; up-to-date procedures for wall control and performance assessment, including limits blasting, scaling, slope support and slope monitoring; and how formal risk management procedures can be applied to each stage of the process.This book will assist in meeting stakeholder requirements for pit slopes that are stable, in regards to safety, ore recovery and financial return, for the required life of the mine.

While historical scholarship has often downplayed the importance of Machiavelli's theory of the state, this study reconstructs the question of lo stato as the conceptual crux of his political philosophy. Peter Stacey offers a detailed reconstruction of the historical context from which Machiavelli's theory emerges, demonstrating how the intellectual and ideological contours of Machiavelli's thinking, as well as much of its content, were decisively shaped by conceptual apparatuses drawn from Roman philosophical, rhetorical and aesthetic discourse. Stacey further provides a sustained analysis of the development of Machiavelli's picture of the state from his earliest writings onwards, underlining the extent to which the Florentine draws deeply upon several key aspects of this intellectual inheritance in hitherto unacknowledged ways, while calling into question some of its cherished assumptions about the character of collective political entities. As Machiavelli's thinking unfolds across The Prince and the Discourses, Stacey illustrates how a strikingly novel conception of the body politic marks him out as the author of a distinctively new philosophy of the state.

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 minesState of the art approaches for challenging designsUse of numerous case histories written by large-open pit operators to illustrate state of practice Individual chapters/sections written by leaders in the industryAs 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.
