Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Coal Mining Investigations in District V Seven typical mines were examined in this District in which there are 33 mines, 21 shipping and 12 local. The total production of the district for the year ended. June was tons or per cent of the total production of the State during the year. The coal mined by machines in District V totaled tons, per cent of the total production of the district. A direct result of undercutting such a large percentage is the use of less powder. The pro duction of the district is per cent of the coal output of the State. For the year ended June 30, 1912, only kegs of powder, per cent of the powder used in the State, were used in the district. There were tons of coal gained for each keg of powder used.

Book excerpt: Excerpt from Panel System of Coal Mining: A Graphical Study of Percentage of Extraction Of 4 to 1 (40-foot rooms on 50-foot centers) is assumed, the highest attainable extraction is per cent. NO better results than these can be reached unless the amount Of coal left in room pillars or in barrier pillars is reduced. As a matter Of fact, the average extraction throughout the State is not more than 50 per cent and in those parts where coal is thickest and lies at greatest depth, the extraction will not average so much. The lowest extractions are due in part to the leaving Of top coal; thus the actual extraction in some districts is lower than that indicated by calculation on an area basis.

This book was released on 2018-02-10 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Occurrence of Explosive Gases in Coal Mines This report presents the results of an investigation begun by the Government in the summer of. 1907, the investigation being started under the immediate supervision of Dr. J. A. Holmes and continued under him as director after it was transferred to the Bureau of Mines in 1910, the field studies being completed in the spring of 1912. The purpose of the investigation was to obtain information on the origin of the inflammable gases in coal and the conditions under which they occur. It was especially intended to ascertain whether there was any relation between the occurrence of gas and the structural or other geologic features of the coal beds. To this end many months were spent in mines and much time was devoted to the examination of mine maps, bore-hole records, and other data made available by the kindness of various coal companies. Ritwo fields of work were selected - one in the northern anthracite basin of Pennsylvania, where the beds are considerably flexed, and the other in the southern part of the bituminous coal field of Illinois, where the beds lie nearly horizontal. In order to take advantage of results of previous investigations of the same general subject, an extended examination was made of reports of various investigators in Europe and America. A digest of the information obtained from these publications is included in the first part of this report, which constitutes an introduction to the discussion of the conditions governing the occurrence of inflammable gas in coal beds.

Available in PDF, EPUB and Kindle. Book excerpt: Much has been written over the years about life in the coal mines of Appalachia. Not surprisingly, attention has focused mainly on the experiences of male miners. In Daughters of the Mountain, Suzanne Tallichet introduces us to a cohort of women miners at a large underground coal mine in southern West Virginia, where women entered the workforce in the late 1970s after mining jobs began opening up for women throughout the Appalachian coalfields. Tallichet's work goes beyond anecdotal evidence to provide complex and penetrating analyses of qualitative data. Based on in-depth interviews with female miners, Tallichet explores several key topics, including social relations among men and women, professional advancement, and union participation. She also explores the ways in which women adapt to mining culture, developing strategies for both resistance and accommodation to an overwhelmingly male-dominated world.

Book excerpt: Excerpt from Reports of Mine Inspectors: For the First, Second and Third Districts of West Virginia, for the Years 1895 and 1896 On being notified of the fact, I went at once to investigate the cause. 1 found the cause to be from blasting coal from the solid, which ignited the dust. I gave them orders to stop shooting coal from the solid, as I had done several times before, also to keep the mine thoroughly watered. Since they have complied with my instructions the mine is in a good and safe condition. As long as they work the mine on the present system, I can see no reason to fear a repetition Of the former disaster.
