Von allen geophysikalischen Prospektionsmethoden ist, was die erreichbare Genauigkeit und die Vielfalt der Anwendungsgebiete betrifft, die Laufzeit- seismik die bedeutendste. Neben den sich speziell in Geophysik ausbildenden Studierenden sind es daher vor allem die Geologiestundenten, fur die es von grossem Interesse ist, in Vorlesungen und UEbungen mit den Auswertungs- methoden der Laufzeitseismik vertraut gemacht zu werden. Das vorliegende Werk soll dabei als Lehr-und Hilfsbuch dienen. Die noetigen mathematischen Vorkenntnisse sind in 111 A prazisiert und koennen bei den Geologiestudenten vorausgesetzt werden. Es versteht sich von selbst, dass das Buch auch von den angehenden Physikern, Vermessungsingenieuren und andern an ange- wandter Geophysik interessierten Studierenden als Lehrmittel und von den in der seismischen Praxis Tatigen als Leitfaden und Hilfsbuch benutzt werden kann. Das Buch besteht aus den funf verschiedenartigen Teilen I bis V: Teil I befasst sich mit einigen grundlegenden Gesichtspunkten und Begriffen, die allgemein die Auswertungsverfahren der geophysikalischen Prospektion betreffen. Teil 11 ist der Hauptteil des Buches. 11 A handelt von den fur die Lauf- zeitseismik massgebenden elastischen Eigenschaften der geologischen Koerper. 11 B fuhrt in die Grundbegriffe der Laufzeitseismik ein. In den Kapiteln 11 C bis 11 L sind die wichtigsten, den Aufbau des Untergrundes betreffenden einfachen Modellfalle behandelt. So wird in 11 C der Untergrund als isotroper, homogener Koerper, in 11 D als aus zwei solchen Koerpern bestehend vorausgesetzt usw. In 11 L schliesslich ist der Untergrund als einachsig anisotroper Koerper angenommen.

Underground coal mining disturbs both the overburden strata and the immediate floor strata. The subject of surface subsidence deals with the issues associated with the movement of overburden strata, which are the layers from the seam to the surface, where structures and water resources important to human activities are located. Surface Subsidence Engineering provides comprehensive coverage of the major issues associated with surface subsidence. The chapters are written by experts on surface subsidence in the three leading coal producing and consuming countries in the world: Australia, China and the United States. They discuss general features and terminologies, subsidence prediction, subsidence measurement techniques, subsidence impact on water bodies, subsidence damage, mitigation and control, and subsidence on abandoned coal mines. In addition, the final chapter addresses some of the unique features of surface subsidence found in Australian coal mines. The book provides information on coal seams ranging from flat to gently inclined to steep to ultra-steep seams. Written for mining engineers, geotechnical engineers and students of mining engineering, this book covers both theories and practices of surface subsidence. Unlike previous publications, it also deals with the subsidence impact on surface and groundwater bodies, crucial resources that are often neglected by subsidence researchers.

This revised edition presents an engineering design approach to ventilation and air conditioning as part of the comprehensive environmental control of the mine atmosphere. It provides an in-depth look, for practitioners who design and operate mines, into the health and safety aspects of environmental conditions in the underground workplace.

Perfect for senior undergraduates and first-year graduate students in geophysics, physics, mathematics, geology and engineering, this book is devoted exclusively to seismic wave theory. The result is an invaluable teaching tool, with its detailed derivations of formulas, clear explanations of topics, exercises along with selected answers, and an additional set of exercises with derived answers on the book's website. Some highlights of the text include: a review of vector calculus and Fourier transforms and an introduction to tensors, which prepare readers for the chapters to come; and a detailed discussion on computing reflection and transmission coefficients, a topic of wide interest in the field; a discussion in later chapters of plane waves in anisotropic and anelastic media, which serves as a useful introduction to these two areas of current research in geophysics. Students will learn to understand seismic wave theory through the book's clear and concise pedagogy.

As the shale revolution continues in North America, unconventional resource markets are emerging on every continent. In the next eight to ten years, more than 100,000 wells and one- to two-million hydraulic fracturing stages could be executed, resulting in close to one trillion dollars in industry spending. This growth has prompted professionals experienced in conventional oil and gas exploitation and development to acquire practical knowledge of the unconventional realm. Unconventional Oil and Gas Resources: Exploitation and Development provides a comprehensive understanding of the latest advances in the exploitation and development of unconventional resources. With an emphasis on shale, this book: Addresses all aspects of the exploitation and development process, from data mining and accounting to drilling, completion, stimulation, production, and environmental issues Offers in-depth coverage of sub-surface measurements (geological, geophysical, petrophysical, geochemical, and geomechanical) and their interpretation Discusses the use of microseismic, fiber optic, and tracer reservoir monitoring technologies and JewelSuite (TM) reservoir modeling software Presents the viewpoints of internationally respected experts and researchers from leading exploration and production (E&P) companies and academic institutions Explores future trends in reservoir technologies for unconventional resources development Unconventional Oil and Gas Resources: Exploitation and Development aids geologists, geophysicists, petrophysicists, geomechanic specialists, and drilling, completion, stimulation, production, and reservoir engineers in the environmentally safe exploitation and development of unconventional resources like shale.
