Excerpt from Mines Producing Low-Sulphur Coal in the Central District The list is presented with some reservations. In the first place the' determination of the sulphur content is based largely upon the analysis of face samples. In taking such samples, the sampler, as is generally known, rejects all impurities more than to BA inch in thickness, and care is taken that fragments of the roof, floor, or clay bands are not included in the sample. Accordingly a face sample commonly shows better coal than is usually mined from the same face. However, comparisons of analyses of face and car samples from Illi nois mines in the low - sulphur district show very little difference, and not always to the advantage of the face sample. So that while it is well to point out the nature of the evidence, apparently no great allowance needs to be made for the fact that the data are largely based upon the analyses of face samples.

Excerpt from Tests on Clay Materials Available in Illinois Coal Mines During the first season, the collection of samples was made inci dental to the regular field work of the geologists, and some actual sampling was done by the mining companies. Twenty - three samples were collected and tested during the winter of 1912-13 and designated as Group 1. The desirability of systematic sampling was recognized, and during the summer of 1913 one man's entire attention was given to this work. Eighty-three samples were collected, and in this report they are designated as Group II. The tests on this series were similar to those for Group I, but more efficient means were devised during the second season for grinding and molding-the material.

Excerpt from Analyses of Coals Purchased by the Government During the Fiscal Years 1908-1915 The analyses given herein are of samples taken from commercial deliveries. In making a comparison of analyses of commercial ship ments with analyses of samples collected from the face of the bed in the mine, due allowance must be made for the larger proportion of impurities that may be included in the commercial operation of the mine. It is difficult to take a mine sample in which the impurities are rejected in exactly the same manner as is done by the miner. The practice of different miners will vary, especially if rigid inspec tion at the tipple is not enforced. In some mines, for instance, where the coal bed has friable partings or has a soft, flaky roof or floor, the inclusion of some foreign matter is unavoidable. Hence, the analysis of the mine sample usually indicates a better grade of coal, as regards ash content and heating value, than the actual commercial shipments, and for this reason the mine sample should be considered as representing the coal that can be produced under only the most favorable conditions of mining and preparation. In commercial shipments that are sampled at their destination the moisture content may be either more or less than that in the mine samples, the relative proportions depending on the amount of bed moisture, the size of the coal, and the weather conditions during transit. Analyses representing many shipments and a large tonnage more truly indicate the general quality of a particular coal than does a single analysis from a. Specially prepared shipment, or analyses of carefully selected mine samples. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Collection of Representative Coal Refuse Samples for Leachate Generation Studies The cleaning of coal is an important part of the coal mining industry. Impurities associated with coal or introduced as a consequence of the mining process are removed by cleaning, which provides a more marketable product. Coal refuse generated from the cleaning process is usually composed of two waste types, gob and slurry, which differ in physical characteristics and methods of disposal.

Excerpt from Coal and the Coal Mines In treating of so large a theme in so small a compass it is impossible to do more than make an outline sketch. It has been the aim of the author to give reliable information free from minute details and technicalities. That information has been, for the most part, gathered through personal experience in the mines. The literature of this special subject is very meagre, and the author is unable to acknowledge any real indebtedness to more than half a dozen volumes. First among these is the valuable treatise on "Coal Mining," by H. M. Chance of the Pennsylvania Geological Survey. Other volumes from which the author has derived considerable information are the State geological reports of Pennsylvania, the mine inspector's reports of the same State, and the "Coal Trade Annuals," issued by Frederick E. Saward of New York. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
