This book was released on 1970 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Do coal mine operators use many mine timbers? What are the specifications for mine timbers? Does producing mine timbers differ from producing other sawmill products? These are typical of the questions that sawmill operators in the Appalachians ask about the mine-timber market. At first glance it seems strange that they would ask such questions. After all, the mine-timber market is a traditional outlet for wood products in the Appalachians, and it would seem that all sawmill operators in the region would be familiar with the market. But this is not the case. Sawmill operators, unless they sell mine timbers, know little about the market. Even those who sell mine timbers know little about the coal industry's current and potential need for mine timbers, because they generally supply only one or two mines. This report was prepared to answer some of the questions that sawmill operators have about the rnine-timber business in the Appalachian coal region. S3

Available in PDF, EPUB and Kindle. Book excerpt: 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.
