Book Description
Excerpt from State Mining Laws on the Use of Electricity in and About Coal Mines The first State to have a coal-mining law was Pennsylvania, which enacted a law, for Schuylkill County only, in 1869. The first State to enact a coal-mining law governing all the coal mines in the State was Illinois in 1872, followed by Ohio in 1873. Pennsylvania in 1870 enacted a law for anthracite mines only, but did not enact similar laws for bituminous mines until 1877. At least 10 other States enacted coal-mining laws between the years 1870 and 1890. Before 1890 electricity was little used in coal-mining operations and therefore practically no provisions governing the installation, inspection, or maintenance of electrical equipment were made in any of the laws enacted up to 1890. In the law of Colorado, approved April 8, 1885, there is a reference to the use of telephones, probably the first reference to electrical equipment of any kind in a State mining code.

Book Description
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.

Book Description
Excerpt from Coal and the Coal Mines IN treatingof so large a theme in so small a compass it is impossible to do more than make an outline sketch. It has been the aim of the author to give reliable information free from minute details and technicalities. That information has been, for the most part, gathered through personal experience in_ithe mines. Literature of this special subject is very meagre, and the author is unable to acknowledge any real indebtedness to more than half a dozen volumes. First among these is the valuable treatise on Coal Mining, by H. M. Chance of the Pennsylvania Geological Survey. Other volumes from which the author has derived considerable information are the State geological reports of Pennsylvania, the mine in.
