This third edition includes greater information than the second edition, with regard to the use of numerical codes to analyse and study the changes in stress and displacement resulting from underground excavation. It also contains additional data concerning the state of stress underground, as well as a number of minor improvements to text and figures.

Permeability is a physical property in rocks of extreme importance in energy engineering, civil and environmental engineering, and various areas of geology. Early on, fractures in fluid flow models were assumed to be rigid. However, experimental research and field data confirmed that stress-deformation behavior in fractures is a key factor governing their permeability tensor. Although extensive research was conducted in the past, the three-dimensional stress-permeability relationships, particularly in the inelastic deformation stage, still remain unclear. In this paper, laboratory experiments conducted on large concrete blocks with randomly distributed fractures and rock core samples are reported to investigate fluid flow and permeability variations under uniaxial, biaxial and triaxial complete stress-strain process. Experimental relationships among flowrate, permeability and fracture aperture in the fractured media are investigated.

Given the complexity involved when modeling heterogeneous and anisotropic formations, this condition is usually ignored, supposing that the well is surrounded by a homogenous and isotropic medium. The main objective of this paper is to present a method that shows the error that might occur when the condition of homogeneity and isotropy is not satisfied, when determining collapse pressure in a formation containing planes of weakness. Although the literature presents some studies, there is not a clear method for determining the collapse pressure of a well that takes into account the mechanical properties of the planes of weakness contained in the formation. The proposed method is based on the Mohr Coulomb criterion for homogeneous and isotropic formations and the criterion of Jaeger and Cook for laminated anisotropic media. It constitutes a robust tool that calculates the collapse pressure in highly complex configurations, contributing thus to prevent waste of time and money by more accurately considering the actual behavior of laminated formations.

Full text PDF. Stress state in rock mass is the most important factor affecting processes around mine working. The goal is to develop methods of calculating stress state in rock masses depending on the elastic and viscous rock properties and interaction of tectonic plates considering stresses measured in individual points.

Ostadhassan, M.. The importance of the geomechanical modeling and wellbore instability analysis is increasing in the petroleum industry with recent growth of drilling plans in unconventional reservoirs. Recently, a large majority of field developments are occurring in shale oil and shale gas reservoirs as a novel source of energy. Many of these reservoirs are thin and highly layered, anisotropic and naturally fractured; these make their geomechanical modeling and wellbore instability analysis remarkably crucial; subsequently a good understanding of elastic properties of the formation such as Young's modulus, Poison's ratio and in-situ stresses are necessary for accurate results. Bakken Formation is one of the major unconventional plays in North America which is identified by three distinct members: layered upper and lower shale and fractured middle dolomite.

Theoretical Rock Mechanics for Professional Practice. The planned rock mechanics textbook is a synthesis of 22 classic texts on rock mechanics, solid mechanics, the author's 15 years' experience in rock mechanics in the gold mining industry, and 10 years as a professor at the University of Pretoria Throughout this period, the author noted that all the introductory texts on stress and strain were incomplete in one way or another, and that this, together with the watered-down introductions to stress and strain currently accepted in the mining rock mechanics fraternity, forms a barrier to the rest of rock mechanics.

Фонтейн, которого он знал, был внимателен к мелочам и требовал самой полной информации. Он всегда поощрял сотрудников к анализу и прояснению всяческих нестыковок в каждодневных делах, какими бы незначительными они ни казались. И вот теперь он требует, чтобы они проигнорировали целый ряд очень странных совпадений. Очевидно, директор что-то скрывает, но Бринкерхоффу платили за то, чтобы он помогал, а не задавал вопросы.

Я же просил меня подбросить.

Стратмор был блестящим специалистом, возможно, лучшим в агентстве. И в то же время после провала с Попрыгунчиком Стратмор испытывал колоссальный стресс. Это беспокоило Фонтейна: к коммандеру сходится множество нитей в агентстве, а директору нужно оберегать свое ведомство. Фонтейну нужен был кто-то способный наблюдать за Стратмором, следить, чтобы он не потерял почву под ногами и оставался абсолютно надежным, но это было не так-то. Стратмор - человек гордый и властный, наблюдение за ним следует организовать так, чтобы никоим образом не подорвать его авторитета.

 Я должен идти. Он извинился перед немцем за вторжение, в ответ на что тот скромно улыбнулся. - Keine Ursache. Беккер вышел в коридор.

Я думала, что потеряла. Он потер виски, подвинулся ближе к камере и притянул гибкий шланг микрофона ко рту. - Сьюзан. Она была потрясена. Прямо перед ней во всю стену был Дэвид, его лицо с резкими чертами.
