Book Description
Excerpt from Statistics of Mines and Mining: In the States and Territories West of the Rocky Mountains, Being the Sixth Annual Report In my fifth annual report, rendered. In 1873, the stamp-mill process, as it exists in California in its greatest perfection, was thoroughly de scribed, with workin g-drewin gs so complete as to be suitable for use by the miners of less favored districts. In the same volume the important subjects of economy in smelting and of the calorific value of the west ern lignites received further treatment. A new topic was introduced by the thorough description, never before given, I believe, with such full ness and accuracy, of the American process of hydraulic mining, to which account a discussion of the Pliocene rivers of California, the sources of hydraulic deposits, constituted an appropriate introduction. This report contained also a chapter on the dressing of ores, a subject which every year brings into greater prominence in this country, as the amount of tailings and low-grade ores, accumulated in our mining dis tricts, grows larger, and the truth impresses itself more clearly upon our mining communities that the successful treatment of these classes of material is the only permanent basis for an extensive mining industry. The report of 1873 contained, also, numerous drawings of mining ma chinery, intended to illustrate the latest patterns which experience has led the manufactories of the Pacific coast to adopt. It was, moreover, accompanied with a copy of an excellent geological map of the United States, universally acknowledged to be the most convenient and trust worthy yet published. It should be added, as a feature of no small importance to the useful ness of these volumes, that each one of them is provided with a triple alphabetical index of mines, mining districts, and subjects, so that the information they contain can be instantaneously referred to when it is needed.

Book Description
The Office of Industrial Technologies (OIT) of the U. S. Department of Energy commissioned the National Research Council (NRC) to undertake a study on required technologies for the Mining Industries of the Future Program to complement information provided to the program by the National Mining Association. Subsequently, the National Institute for Occupational Safety and Health also became a sponsor of this study, and the Statement of Task was expanded to include health and safety. The overall objectives of this study are: (a) to review available information on the U.S. mining industry; (b) to identify critical research and development needs related to the exploration, mining, and processing of coal, minerals, and metals; and (c) to examine the federal contribution to research and development in mining processes.

Book Description
"At the conclusion of the 110-day coal miners' strike in March of 1978, President Carter appointed John D. (Jay) Rockefeller IV to head up the first major federal study of coal mining in America in three decades. One of the main tasks of the President's Commission on Coal (PCC) was, in the words of Ben Franklin who covers coal for the New York Times, to "search out the roots of labor management bitterness that not only prolonged the record walkout but for decades has resulted in strikes every three years." To President Carter, who expressed a desire to place greater emphasis on domestically produced coal as an energy source, and to business interests, there were questions of great importance." -- review essay by Alan Banks, Appalachian Journal , SUMMER 1982, Vol. 9, No. 4 (SUMMER 1982), pp. 295-301.
