Hard Rock Hydraulics


Book Description

Hard rock hydraulics concerns arrangements of adjoining intact rock blocks, occurring down to a depth of hundreds of meters, where groundwater percolates within the gaps between these blocks. During the last decades, technical papers related to successful or failed attempts for mining groundwater from hard rocks, and achievements or failures of public or mining developments with respect to these rocks, increased the knowledge of their hydraulics. Examples of activities where the mechanical behavior of these rocks highly interacts with their hydraulics are projects under the sea or groundwater level, such as open pits or underground mines, galleries, tunnels, shafts, underground hydropower plants, oil and LPG storage caverns, and deep disposal of hazardous waste. This book dedicated to hard rock hydraulics assumes some prior knowledge of hydraulics, geology, hydrogeology, and soil and rock mechanics. Chapter I discusses the main issues of modeling; chapter II covers the fundamentals of hard rock hydraulics; chapter III presents concepts regarding approximate solutions; chapter IV discusses data analysis for groundwater modeling; chapter V focuses on finite differences and chapter VI provides examples of some particular unusual applications. This book will help civil and mining engineers and also geologists to solve their practical problems in hydrogeology and public or mining projects.




Fractured Rock Hydraulics


Book Description

Uniquely devoted to hard and fractured rock hydraulics, this advanced-level introduction provides tools to solve practical engineering problems. Chapter I covers the fundamentals of fractured rock hydraulics under a tensor approach. Chapter II presents some key concepts about approximate solutions. Chapter III discuss a few data analysis techniques applied to groundwater modeling. Chapter IV presents unique 3D finite difference algorithms to simulate practical problems concerning the hydraulic behavior of saturated, heterogeneous and randomly fractured rock masses without restriction to the geometry and properties of their discontinuities. Supported by examples, cases, illustrations and references, this book is intended for professionals and researchers in hydrogeology, engineering geology, petroleum reservoir, rock and hydraulic engineering. Its explanatory nature allows its use as a textbook for advanced students.




Ground Mechanics in Hard Rock Mining


Book Description

This book illustrates the advantages of the application of ground mechanic concepts to hard rock mining. It examines the ground stability for various mine layouts using specific case histories. The book deals with ground support, reinforcement, and stabilization of mining structures.




Groundwater Geophysics in Hard Rock


Book Description

In hard rock terrain, shallow water wells generally have a poor to moderate yield. Sinking wells deeply to tap yielding fracture zones often backfires, because the borehole may miss the saturated fracture zones at depths. A wrong approach to groundwater exploration in hard rock has therefore often led to unnecessary recurring expenditures and waste




Hard Rock Mine Reclamation


Book Description

Hard rock mines have significant effects on the territories where they operate, through both infrastructure construction as well as resource use. Due to their extractive activities, these mines store large quantities of wastes at the surface, which can be both physically and chemically unstable. Reclamation aims to return a mine site to a satisfactory state, meaning that the site should not threaten human health or security, should not generate in the long term any contaminant that could significantly affect the surrounding environment, and should be aesthetically acceptable to communities. This book focuses on the reclamation of waste storage areas, which constitute the main source of pollution during and after mine operations, and especially issues with acid mine drainage and neutral contaminated drainage. Features: Provides fundamental information and describes practical methods to reclaim mine-waste facilities Compares the different methods and illustrates their application at sites through case studies Identifies new reclamation issues and proposes solutions to address them Presents existing and new technologies to reclaim mine waste disposal areas from hard rock mines in different climatic conditions Integrates reclamation into mine operations and long term performance of techniques used through an interdisciplinary approach With mine site reclamation a young and still emerging science, the training needs for professionals and students working in this field are huge. This book is written from an engineering point of view and in it the authors identify new reclamation issues and propose well-tested as well as innovative approaches to addressing them. Students in graduate programs focused on mines and the environment as well as professionals already working in departments related to mine site reclamation will find this book to be a valuable and essential resource.




Groundwater Dynamics in Hard Rock Aquifers


Book Description

This book contains the results and findings of the advanced research carried out in a pilot area with a thorough investigation of the structure and functioning of an aquifer in a granitic formation. It characterizes the hard rock aquifer system and examines its properties and behavior as well as systematically details the geophysical, geological and remote sensing applications to conceptualize such an aquifer system.

Hydraulic Structures


Book Description

This book discusses in detail the planning, design, construction and management of hydraulic structures, covering dams, spillways, tunnels, cut slopes, sluices, water intake and measuring works, ship locks and lifts, as well as fish ways. Particular attention is paid to considerations concerning the environment, hydrology, geology and materials etc. in the planning and design of hydraulic projects. It also considers the type selection, profile configuration, stress/stability calibration and engineering countermeasures, flood releasing arrangements and scouring protection, operation and maintenance etc. for a variety of specific hydraulic structures. The book is primarily intended for engineers, undergraduate and graduate students in the field of civil and hydraulic engineering who are faced with the challenges of extending our understanding of hydraulic structures ranging from traditional to groundbreaking, as well as designing, constructing and managing safe, durable hydraulic structures that are economical and environmentally friendly.
