Electrotechnology In Mining

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.

A consideration of the early development of electricity in a major British coalfield and an investigation into how such a well-established, labour-intensive industry upon which the prosperity of the local community depended was able to respond to the challenge of new technology.

Excerpt from Electricity in Coal Mining Many good engineering handbooks are to be found dealing with the details of electrical construction and the installation of mining machinery but the writer feels that there maybe a demand for a small treatise covering, in a general way, the many phases of electrical engineering as applied to coal mining. Such a book would probably be of use to the investor or the operator in outlining methods of procedure and to the operating engineer in tracing the foundations upon which an electrical power plant may be established and operated in the most efficient manner. In securing data upon which some of the machinery is described and for many of the photographs from which cuts have been made the writer wishes to acknowledge the help of the General Electric Co., Westinghouse Electric and Manufacturing Co., Goodman Manufacturing Co., Jeffrey Machine Co., and other manufacturers who have assisted in the work. The writer also wishes to acknowledge his indebtedness to the Editors of Coal Age for manuscript corrections and to the McGraw-Hill Book Co. Inc., for the able manner in which the work of publishing has been carried out. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
