Book Description
This book examines the water resistance capacity of the Upper Ordovician limestone and its feasibility as a water barrier to achieve safe and green mining. Mine water inrush events often occur during coal mine construction and production; they account for a large proportion of the coal mine disasters and accidents in China, second only to gas explosions. As mining depths and mining intensity continue to increase, the hydrogeological conditions encountered are becoming more complex. This book describes in-situ methods designed to test the water resistance of the limestone layer, as well as specific grouting techniques developed to transform this layer into a barrier that can prevent water inrush during mining. The innovative technologies, which were applied and validated in two coal mines, are applicable to other coal mines or any underground engineering works.

Book Description
Professionals and students in any geology-related field will find this an essential reference. It clearly and systematically explains underground engineering geology principles, methods, theories and case studies. The authors lay out engineering problems in underground rock engineering and how to study and solve them. The book specially emphasizes mechanical and hydraulic couplings in rock engineering for wellbore stability, mining near aquifers and other underground structures where inflow is a problem.

Book Description
This book addresses the processes related to mine abandonment from a hydrogeological perspective and provides a comprehensive presentation of water management and innovative tracer techniques for flooded mines. After an introduction to the relevant hydrogeochemical processes the book gives detailed information about mine closure procedures. The book also includes case studies and hints, and some new methodologies for conducting tracer tests in flooded mines.

Book Description
This volume in the Encyclopedia of Sustainability Science and Technology, Second Edition, brings together chapters examining water, energy, minerals and the environment in a holistic approach to land use planning and utilization. The work examines some of the problems, techniques, and solutions for managing resources so that a balance can be maintained between development and the environment. As world population increases, greater demand is placed on finite resources that earth can provide. Geographic areas once judged inadequate or inappropriate for construction, water and wastewater management, or transportation routes, among other activities, are being considered for, and being used, for development. Topics covered in this volume include impacts of natural disasters such as earthquakes and sinkholes, water and its use, overuse, and role in energy generation, and carbon sequestration. The topics covered here all play a role in development and the potential to sustain a growing world population. Interactions among system components mean that no single aspect can be addressed without including another. Environmental Geology places these different factors into perspective so that scientists, politicians, economists, planners, and stakeholders can work together to develop solutions that provide an acceptable balance between development and the environmental services on which we all depend.

Book Description
No engineering structure can be built on the ground or within it without the influence of geology being experienced by the engineer. Yet geology is an ancillary subject to students of engineering and it is therefore essential that their training is supported by a concise, reliable and usable text on geology and its relationship to engineering. In this book all the fundamental aspects of geology are described and explained, but within the limits thought suitable for engineers. It describes the structure of the earth and the operation of its internal processes, together with the geological processes that shape the earth and produce its rocks and soils. It also details the commonly occurring types of rock and soil, and many types of geological structure and geological maps. Care has been taken to focus on the relationship between geology and geomechanics, so emphasis has been placed on the geological processes that bear directly upon the composition, structure and mechanics of soil and rocks, and on the movement of groundwater. The descriptions of geological processes and their products are used as the basis for explaining why it is important to investigate the ground, and to show how the investigations may be conducted at ground level and underground. Specific instruction is provided on the relationship between geology and many common activities undertaken when engineering in rock and soil.

Book Description
Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.

Book Description
This practical training guidebook makes an important contribution to karst hydrogeology. It presents supporting material for academic courses worldwide that include this and similar topics. It is an excellent sourcebook for students and other attendees of the International Karst School: Characterization and Engineering of Karst Aquifers, which opened in Trebinje, Bosnia & Herzegovina in 2014 and which will be organized every year in early summer. As opposed to more theoretical works, this is a catalog of possible engineering interventions in karst and their implications. Although the majority of readers will be professionals with geology/hydrogeology backgrounds, the language is not purely technical making it accessible to a wider audience. This means that the methodology, case studies and experiences presented will also benefit water managers working in karst environments.

Book Description
Is it not generally believed that our town is a healthy place . . . a place highly com mended on this score both for the sick andfor the healthy? . . And then these Baths - the so-called 'artery' of the town, or the 'nerve centre' . . . Do you know what they are in reality, these great and splendid and glorious Baths that have cost so much money? . . A most serious danger to health! All that filth up in Melledal, where there's such an awful stench - it's all seeping into the pipes that lead to the pump-room! Henrik Ibsen, An Enemy of the People, 1882 Henrik Ibsen gave the 'truth about mineral water' more than 100 years ago in An Enemy of the People. His examples came not from the decadent bathing spas of Bohemia or Victorian Britain, but from the very edge of polite society, subarctic Norway! His masterpiece illustrates the central role that groundwaters and, in particular, mineral waters have played in the history of humanity: their economic importance for towns, their magnetism for pilgrims searching for cures, the political intrigues, the arguments over purported beneficent or maleficent health effects and, finally, their contami nation by anthropogenic activity, in Ibsen's case by wastes from a tannery. This book addresses the occurrence, properties and uses of mineral and thermal groundwaters. The use of these resources for heating, personal hygiene, curative and recreational purposes is deeply integrated in the history of civilization.
