Sobre este producto
- 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. As such, some type characters and images might suffer from slight imperfections or minor shadows in the page background.
