Both mining and electrical engineers need to bear in mind the following specific requirements of electrical applications in mining. 1) Economy of electrical plant and equipment in relation to the cost price of the extracted mineral ores, governed by the specific exploitation conditions, 2) Reliability of electrical plant and equipment for extractive operations, operational efficiency, and plant and personnel safety. 3) Special safeguards to counteract the additional hazards posed by the use of electric power, and by electrical phenomena in general. The book has been written along these lines, dealing with those topics which highlight the aspects of electrical engineering of relevance for mining engineers and aspects of mining operations that electrical engineers need, to meet the above-mentioned basic requirements governing the introduction and use of electrical plants and systems in mines.This book is intended as a text book and will be of use to students, and colleges as well as to mining and electrical engineers.
Changes in size and power of available mining transport equipment, combined with improved means of control involving leaky feeder radio and computers, demands a new look at the problem of mine winding and transport. Such changes require the traditional mining engineer to have a much greater engineering application. This book is intended to satisfy that requirement.All the important means of transporting operatives and minerals are addressed, both below ground and on the surface. Safe, speedy and economic transport from the point of mineral extraction to leaving the mine is paramount. This work covers all aspects of the problem including: (1) the design and application of steel wire ropes to a variety of industrial applications, and the various drums and pulleys necessary; (2) a ready means of calculating output/throughput of various transport modes, and relating such to their power requirement; and (3) information on transport modes that enables the most suitable system for given conditions to be determined.A ``first principle'' approach has been adopted throughout, and extensive use of practical examples allows the solution of virtually all associated problems. Although formulae are used where necessary for an understanding of the content, the numerous tables included enable the practicing engineer to make short cuts to more quickly solve particular problems. In addition, the provision of a considerable number of operational constants, many not previously published, enable a more speedy and accurate solution to be effected. By comparing the calculated solutions to a particular problem, the most economic transport mode may be determined.Mining, mechanical and electrical engineers concerned with the safe movement of men or material will find this book of particular use, as will the student preparing for examinations on the subject.
The escalating worldwide demand for energy has had the effect, among other things, of promoting the development of coal mining. In some countries specialist design offices were set up and students trained as specialists in mine design and construction. Poland, a country having mining traditions stretching over many centuries, is a good example, and has gained a place in the forefront, not only as a coal producer and exporter, but also as an originator and exporter of technical mining know-how. The author of this book has himself had 25 years of practical experience in mine design, in the supervision of mining investment implementation both at home and abroad, and also in directing the activities of the Chief Mine Design and Studies Office in Poland, plus more than 20 years' teaching experience in the training of mining engineers, in particular as head of the Mine Design Department of the Mining Faculty at the Silesian Polytechnic University in Gliwice. This vast wealth of experience has prompted him to write the present book which discusses the basic problems met with in the design of underground hard-coal mines.The author's primary aim has been to deal with all those questions in mine design which have not yet been answered in mining textbooks and which, from his own personal experience, he considers to be of importance. Accordingly, he presents the general principles governing the design of new mines and the reconstruction of working mines, the development of mining regions, the design of coal-preparation plant, and energy economy in mines. Making use of the broad experience gained by the Polish mining industry in the implementation of mining investment projects, he has quoted several examples of technical and organizational solutions which effectively shorten the mine construction cycle.The book is addressed chiefly to investors and engineers engaged in preparing plans for the development of mining regions, for the construction of new mines, and the reconstruction of existing mines and preparation plants, as well as to students in mining departments of technical schools and universities. The information offered here is of great practical value and may well stimulate the development of new ideas for design and implementation concepts.
The Office of Industrial Technologies (OIT) of the U. S. Department of Energy commissioned the National Research Council (NRC) to undertake a study on required technologies for the Mining Industries of the Future Program to complement information provided to the program by the National Mining Association. Subsequently, the National Institute for Occupational Safety and Health also became a sponsor of this study, and the Statement of Task was expanded to include health and safety. The overall objectives of this study are: (a) to review available information on the U.S. mining industry; (b) to identify critical research and development needs related to the exploration, mining, and processing of coal, minerals, and metals; and (c) to examine the federal contribution to research and development in mining processes.
Theoretical and technical problems of electromagnetic compatibility (EMC) in mining are covered in this volume. EMC is discussed in three main groups of problems: sources (generation) of interference, propagation of interference in mining conditions, the influence of interferences on mining devices, particularly electronic devices used in deep coal mines. Propagation of interference and its influence on mining communication and signalling systems as well as on control systems of mining machines are discussed. Attention is paid to the influences of interference on dispatching sytems which give to the dispatcher some information about mining hazards. The book will be of interest to mining and electrical engineers.
Jointly sponsored by the China University of Mining and Technology and the University of Nottingham, UK, a total of 187 papers have been included in the proceedings, of which fifty-two are contributed by authors outside of China.

Tech Mining makes exploitation of text databases meaningful tothose who can gain from derived knowledge about emergingtechnologies. It begins with the premise that we have theinformation, the tools to exploit it, and the need for theresulting knowledge. The information provided puts new capabilities at the hands oftechnology managers. Using the material present, these managers canidentify and access the most valuable technology informationresources (publications, patents, etc.); search, retrieve, andclean the information on topics of interest; and lower the costsand enhance the benefits of competitive technological intelligenceoperations.
Advances in technology are making massive data sets common in many scientific disciplines, such as astronomy, medical imaging, bio-informatics, combinatorial chemistry, remote sensing, and physics. To find useful information in these data sets, scientists and engineers are turning to data mining techniques. This book is a collection of papers based on the first two in a series of workshops on mining scientific datasets. It illustrates the diversity of problems and application areas that can benefit from data mining, as well as the issues and challenges that differentiate scientific data mining from its commercial counterpart. While the focus of the book is on mining scientific data, the work is of broader interest as many of the techniques can be applied equally well to data arising in business and web applications. Audience: This work would be an excellent text for students and researchers who are familiar with the basic principles of data mining and want to learn more about the application of data mining to their problem in science or engineering.
This first Issue in the series contains nine articles written by leading British and American experts from the mining industry, regulatory authorities, and academia, and incorporates the latest research. Following an introductory overview of many of the issues of current concern to the field, the book deals with a wide variety of topics, ranging from the environmental impact of gold mining in the Brazilian Amazon, through the issues relevant to coal mining, vegetative and other remediation strategies and procedures and water pollution, to a thorough analysis of environmental management and policy initiatives. The issues raised in Mining and its Environmental Impact may point the way to future solutions to the economic, technological and environmental problems associated with mining in all its aspects and make this volume key reading for practitioners and researchers in the field, as well as for environmentalists generally.
