The Mechanical Behavior of Salt X


Book Description

Rock salt formations have long been recognized as a valuable resource - not only for salt mining but for construction of oil and gas storage caverns and for isolation of radioactive and other hazardous wastes. Current interest is fast expanding towards construction and re-use of solution-mined caverns for storage of renewable energy in the form of hydrogen, compressed air and other gases. Evaluating the long term performance and safety of such systems demands an understanding of the coupled mechanical behavior and transport properties of salt. This volume presents a collection of 60 research papers defining the state-of-the-art in the field. Topics range from fundamental work on deformation mechanisms and damage of rock salt to compaction of engineered salt backfill. The latest constitutive models are applied in computational studies addressing the evolution and integrity of storage caverns, repositories, salt mines and entire salt formations, while field studies document ground truth at multiple scales. The volume is structured into seven themes: Microphysical processes and creep models Laboratory testing Geological isolation systems and geotechnical barriers Analytical and numerical modelling Monitoring and site-specific studies Cavern and borehole abandonment and integrity Energy storage in salt caverns The Mechanical Behavior of Salt X will appeal to graduate students, academics, engineers and professionals working in the fields of salt mechanics, salt mining and geological storage of energy and wastes, but also to researchers in rock physics in general.

Computational Geotechnics


Book Description

In this book, effective computational methods to facilitate those pivotal simulations using open-source software are introduced and discussed with a special focus on the coupled thermo-mechanical behavior of the rock salt. A cohesive coverage of applying geotechnical modeling to the subsurface storage of hydrogen produced from renewable energy sources is accompanied by specific, reproducible example simulations to provide the reader with direct access to this fascinating and important field. Energy carriers such as natural gas, hydrogen, oil, and even compressed air can be stored in subsurface geological formations such as depleted oil or gas reservoirs, aquifers, and caverns in salt rock. Many challenges have arisen in the design, safety and environmental impact assessment of such systems, not the least of which is that large-scale experimentation is not a feasible option. Therefore, simulation techniques are central to the design and risk assessment of these and similar geotechnical facilities.




Proceedings of the 37th International Conference on Ground Control in Mining


Book Description

The International Conference on Ground Control in Mining has a rich history of advancing ground control techniques and knowledge. It provides a unique platform for researchers, regulators, consultants, manufacturers, and mine operators to present and exchange challenging industry topics as well as to expedite solutions to ground control problems that require immediate attention. This proceedings from the 37th International Conference is no exception. It includes 47 peer-reviewed research papers from industry experts covering topics of importance for today and the future.




Gas Generation and Migration in Deep Geological Radioactive Waste Repositories


Book Description

Understanding the behaviour of gases in the context of radioactive waste disposal is a fundamental requirement in developing a safety case for the disposal of radioactive waste. Of particular importance are the long-term performance of bentonite buffers and cement-based backfill materials that may be used to encapsulate and surround the waste in a repository, and the behaviour of plastic clays, indurated mudrocks and crystalline formations that may be the host rocks for a repository. The EC Euratom programme funded project, FORGE, has provided new insights into the processes and mechanisms governing gas generation and migration with the aim of reducing uncertainty. This volume brings together papers on aspects of this topic arising from both the FORGE project and work undertaken elsewhere. This has been achieved by the acquisition of new experimental data coupled with modelling, through a series of laboratory and field-scale experiments performed at a number of underground research laboratories throughout Europe.







The Mechanical Behavior of Salt – Understanding of THMC Processes in Salt


Book Description

A unique opportunity to review the latest progress in an expanding area of interest: the Mechanical Behaviour of Salt. These Proceedings include over fifty papers and summaries describing the latest findings in ongoing studies from a number of research groups. For the 2007 conference, there was a particular focus on the understanding of thermal, mechanical, hydraulic and chemical coupled processes (THMC). Such processes are of specific interest when considering advanced problems in waste disposal, storage and mining. The book includes a number of themes: - laboratory and in-situ investigations modelling, e.g. derivation of constitutive equations - numerical computations and prediction of long-term behaviour - THMC processes in mining projects, storage and permanent disposal - case studies - geology - mining and storage applications and abandonment The International Conferences on the Mechanical Behaviour of Salt have a long tradition, being initiated in 1981 at The Pennsylvania State University, USA. The present conference, the sixth of the series, took place in Hannover, Germany, in May 2007. The conference brought together mining engineers, researchers, and university professors interested in the mechanical behaviour of salt, mostly from Europe and beyond.
