Excerpt from Methods of Mine-Timbering Before Deidesheimer's square set system came into use, the ingen ious placing of posts, caps, and stulls constituted the only method of timbering, the multitude of conditions met in the mines making the combinations almost endless. Where veins occur in firm, solid rock, being perpendicular, or near it, the danger of caving is greatly lessened, and the amount of timber required is reduced to a minimum, but these conditions are exceptional.

Mining historian Kerby Jackson introduces us to a classic mining work in this important re-issue of the California State Mining Bureau publication “Methods of Mine Timbering”. Originally published in 1896, this important publication on mining engineering has not been available for nearly a century.Included are rare insights into historical methods of timbering structural support that were used in underground metal mines during the California that still have a practical application for the small scale hardrock miner of today.

Excerpt from Mine Timbering This book is a collection of articles that have previously been printed in the Engineering and Mining Journal, The Mineral Industry, and the transactions of various societies, the source being stated in a_ foot-note to each article. The article by Mr. Macdonald was published originally in the Proceedings of the Canadian Mining Institute, and that by Mr. Parlee in the Pro ceedings of the Canadian Society of Civil Engineers. Permission to make this republication has been courteously granted by the Secretaries Of both those societies, and the respective authors have cooperated with suggestions and in the reading of proof. The last part of the book is made up chiefly of articles that have appeared in the Engineering and Mining Journal during the last two or three years. In the absence of any treatise on this impor tant subject, which in the hand-books and text - books on mining is dealt with only in a superficial way, it has appeared worth while to make the present collection, which is Offered not as a complete treatise on the subject, but rather as a series of essays which go fully into many important details. It is hoped that a thorough and systematic treatise on mine timbering will soon be written. Editor. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Mining historian Kerby Jackson introduces us to a classic mining publication on Hard Rock Mining by W.H. Storms. Unavailable since 1909, this rare publication provides an in depth look at American methods of underground mine timbering and mining methods.Topics include the selection and preservation of mine timbers, drifting and drift sets, driving in running ground, structural steel in mine workings, timbering drifts in gravel mines, timbering methods for driving shafts, positioning drill holes in shafts, timbering stations at shafts, drainage, mining large ore bodies by means of open cuts or by the “Glory Hole” system, stoping out ore in flat or low lying veins, use of the “Caving System”, stoping in swelling ground, how to stope out large ore bodies, Square Set timbering on the Comstock and its modifications by California miners, the construction of ore chutes, stoping ore bodies by use of the “Block System”, how to work dangerous ground, information on the “Delprat System” of stoping without mine timbers, construction and use of headframes and much more.This volume provides a reference into not only practical methods of mining and timbering that may be employed in narrow vein mining by small miners today, but also rare insights into how mines were being worked at the turn of the 19th Century.Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface.

Excerpt from Coal Mine Surveying The rapid depletion of the primitive forests of America by fires and axe in recent years has raised the price of wood so rapidly that the mining industry is becoming alarmed as to its future supply of the big timber of which it has hitherto been such a prodigal consumer. Economy in the use of timber has been essential to commercial success in European mining for several generations and it was to the Old World that our operators went for their first systems of timberless mining. The use of steel and masonry for the support of mine shafts and tunnels has long been practised in Europe not only because of dear timber but because most mines there are considered to be long-term investments rather than temporary speculations. As this replacement of timber supports by other material involves no new mining system and has been thoroughly covered by other writers, it will not be described in this treatise. Though most of the mining methods considered consume some timber, their economy in that respect is so marked as to justify the use of a title Mining without Timber.
