This book presents some fundamental concepts behind the basic theories and tools of discrete element methods (DEM), its historical development, and its wide scope of applications in geology, geophysics and rock engineering. Unlike almost all books available on the general subject of DEM, this book includes coverage of both explicit and implicit DEM approaches, namely the Distinct Element Methods and Discontinuous Deformation Analysis (DDA) for both rigid and deformable blocks and particle systems, and also the Discrete Fracture Network (DFN) approach for fluid flow and solute transport simulations. The latter is actually also a discrete approach of importance for rock mechanics and rock engineering. In addition, brief introductions to some alternative approaches are also provided, such as percolation theory and Cosserat micromechanics equivalence to particle systems, which often appear hand-in-hand with the DEM in the literature. Fundamentals of the particle mechanics approach using DEM for granular media is also presented. · Presents the fundamental concepts of the discrete models for fractured rocks, including constitutive models of rock fractures and rock masses for stress, deformation and fluid flow · Provides a comprehensive presentation on discrete element methods, including distinct elements, discontinuous deformation analysis, discrete fracture networks, particle mechanics and Cosserat representation of granular media · Features constitutive models of rock fractures and fracture system characterization methods detaiing their significant impacts on the performance and uncertainty of the DEM models

In large surface mining operations, drilling and blasting activities constitute more than 15% of the total costs. In order to optimize performance and minimize costs, a thorough knowledge of drill and blast operations is, therefore, extremely important. In this unique reference volume, rotary blasthole drilling and surface blasting, as applied in large surface mines, are comprehensively covered. Both new and classic concepts, techniques and methodologies are presented, supported by numerous illustrations and practical data. In 26 chapters, drilling, surface blasting, rock, rock mass, machinery, tools and accessories, compressors and air flushing, computing and practice are many other relevant subjects are treated; the first 16 chapters deal with rotary blasthole drilling, and the 10 next chapters with the concepts, theory and practice of blasting. Moreover, the 14 appendices provide vital technical and commercial data, to further support the reader to design, plan, execute, and calculate blasthole drilling operations. This volume is intended for professionals and technicians in mining, exploration, geological and mechanical engineering, who are involved with the design, planning, and execution of rotary drilling and blasting operations in surface mines.

VI Bei der Verfolgung der statischen Aufgaben des Tunnel- und Stollen baues würde man pald an eine unübersteigbare Grenze gelangen, wenn man nicht auf den natur gegebenen Grundlagen, nämlich den mechanischen Eigenschaften des Gebirges, aufbauen könnte. Damit befaßt sich Kap. I des Buches, worin die wichtigsten Erkenntnisse auf diesem Gebiet geschildert werden. Aber auch die beiden folgen den Kap. II und III, wo der primäre und sekundäre Spannungszustand des Ge birges behandelt werden, gehören ihrem Wesen nach noch zu den Grundlagen, wenngleich sie schon viele Ausblicke auf die Probleme des untertägigen HohIraum baues und vor allem des Gebirgsdruckes gestatten. Die Frage der Belastung eines Tunnel-oder Stollenausbaues, also des Gebirgsdruckes im weitesten Sinn des Wortes, stellt ein besonderes Anliegen der Tiefbautechnik und des Bergbaues dar. Es ist erstaunlich, wie weit die Meinungen hierüber auseinandergingen, und es war daher angezeigt, die Entwicklung der Gebirgsdruckfrage wenigstens in groben Zügen in Kap. IV zu schildern, die zutreffenden Erkenntnisse früherer Zeiten zu verwerten und Fehlbeurteilungen, auch dann, wenn sie heute noch Anhänger besitzen, als solche zu kennzeichnen, um auf diesem Wege zu einer richtigen Deutung zu ge langen. Kritische Betrachtungen ließen sich dabei nicht vermeiden; sie sollen aber, wie übrigens auch in allen anderen Buchteilen, nur der Sache dienen. In weiterer Verfolgung der Zielsetzung des Buches werden dann die Bemessungs aufgaben im Lockergebirge in Kap. V und bei Auftreten von echtem Gebirgsdruck in Kap. VI behandelt, wobei, wie bereits erwähnt wurde, die Bestimmung der Belastung des Ausbaues im Vordergrund der Untersuchungen steht.

Porosity plays a clearly important role in geology. It controls fluid storage in aquifers, oil and gas fields and geothermal systems, and the extent and connectivity of the pore structure control fluid flow and transport through geological formations, as well as the relationship between the properties of individual minerals and the bulk properties of the rock. In order to quantify the relationships between porosity, storage, transport and rock properties, however, the pore structure must be measured and quantitatively described.Porous Rock Fracture Mechanics focuses on the fracture mechanics of porous rocks and modern simulation techniques for progressive quasi-static and dynamic fractures. The topics covered in this volume include a wide range of academic and industrial applications, including petroleum, mining, and civil engineering. The goal of this book is to summarize, in a manner the reader can use for future experimental work, many of the techniques for analyzing the porosity of rocks or other porous materials. The mechanisms pertaining to percussion drilling and blasting are investigated, with specific reference to the application of fracture mechanics. In order to gain an improved understanding of the mechanisms controlling rock fragmentation, a multidisciplinary approach is followed which includes laboratory experiments conducted in plexiglass and rock, in-situ field experiments and analytical/numerical modeling techniques.This book discusses scattering methods for porosity analysis, petrophysical approaches, and image analysis approaches. Chapters focus on advanced topics in the field of rock's fracture mechanics and address theoretical concepts, experimental characterization, numerical simulation techniques, and their applications as appropriate. The increased attention paid to experimental rock fracture mechanics has led to major contributions to the solving of geophysical problems.This book serves as an important guiding tool for petroleum, geomechanics, drilling and structural engineers, Civil Engineers, Material Scientists, R&D managers in industry and academia as well as researchers in this field find this book beneficial.
