From Significance and value of Analyses of Coal: "The analyses published in this report cover samples of coal collected in many different parts of the country with unusual care by experiences men, in such manner as to make them representative of extensive beds of coal."
Description:
From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and ina…

Description:
From Introduction: "The lack of comparable and accurate statistics of coal-mine accidents in the united States as a whole led the Bureau of Mines in 1911 to undertake the collection of such data. The mining departments of the leading foreign coal-producing countries have long taken cognizance of the importance of statistics. The bureau feels that in presenting the tables embodied in this report it is offering the and comparable statistics of coal-min accidents for the country as a whole that ha…

Description:
From Introduction: "In investigating general problems that relate to the fuel resources of this country, and in testing fuels belonging to or for the use of the Government, the Bureau of Mines has given considerable attention to the efficiency and economic value of producer-gas power plants. This feeling of commercial decadence has become so general that the facts gleaned from an inspection of the summaries and charts presented in this bulletin will undoubtedly surprise those who have regarded …

Description:
From Introduction: "The purpose of the investigation discussed in this bulletin, one of a series dealing with the use of electricity in mines, was to study the various means and methods used to confine the flashes that occur when a switch carrying electric current is opened."
Description:
From Introduction: "This report has been prepared, not only for the purpose of recoding the results of the first series of coal-dust tests conducted in the experimental mine of the Bureau of Mines, but also to place before the mining public a description of the mine and an account of the objects sought in an its establishment."

Description:
From Introduction: "Among the investigations that the Bureau of Mines is conducting with a view to increasing efficiency in utilization of fuels belonging to or for the use of the Government is an investigation of the processes that take place in a foundry cupola during a melt."
Description:
Report discussing a series of fuel-testing investigations that U.S. Geological Survey began in 1904 for the purpose of analyzing and testing the coals and lignites in the United States in order to determine their fuel values and the most efficient methods of utilizing them for different purposes. Types of tests undertaken included chemical analyses, steaming tests, gas-producer tests, briquetting tests, coking tests, and washing tests of samples collected from the various coals fields of the co…

Description:
For Introduction: "For these reasons an investigation of the mining, preparation, and use of fuller's earth in this country, especially in its application to edible oils, was conducted in order to ascertain why our own raw material has been deemed inapplicable to our needs."
Description:
Report issued by the Bureau of Mines over studies conducted on hydraulic mine filling. The different uses of this type of mine filling are discussed. This report includes tables, and illustrations.
Description:
From Introduction: "As part of the investigations of the cause of mine accidents and of the safest and most efficient methods of handling electricity underground, the Bureau of Mines undertook a study of ignition of mine gases by the filaments of electric incandescent lamps. This bulletin describes the investigation in detail and gives a complete record of the results obtained."
Description:
From Introduction: "The conclusions are given in this bulletin, which is published by the Bureau of Mines as one of the series of publications dealing with the testing of explosives and the precautions that should be taken to increase safety and efficiency in the use of explosives in mining operations. The results of the experiments described in this bulletin show that the average percentage of failures of explosives to detonate was increased more than 20 per cent when the lower grades of elect…

Description:
From Introduction: "Much knowledge has been gained from the work done in the large galleries constructed at official and semiofficial stations in this country and abroad, but the study of the coal-dust problem in these galleries requires so much time and is so costly that there is a need of a reliable laboratory method for obtaining a classification if the great variety of dusts that occur in mines. The investigation described in this paper was an attempt to devise such a method."

Description:
Technical paper issued by the Bureau of Mines over studies on metallurgical coke. As stated in the introduction, "in this paper the attempt is made to summarize the history of coke making in the United States, to indicate the development of different methods and the modern types of ovens, and to point out the composition and physical properties of the metallurgical cokes produced in this country" (p. 5). This paper includes tables, illustrations, photographs, and a map.
Description:
From Introduction: "The investigation here reported has to do only with the dikes of the southern Appalachian region, in which abundance of each mineral is as in the order given above."
Description:
From Introduction: "It this report endeavor has been made to eliminate all unnecessary remarks; but in order that those who hold diverging views regarding the subjects discussed may have before them the arguments that led the conferees to vote for the 36 resolutions adopted, the discussion had in the committees and in open session is published practically in full. Moreover, for the information of those mining officials, operators, and surgeons who are unfamiliar with approved methods of first-a…

Description:
From Introduction: "The purpose of the studies that form the basis of this report was to learn from microscopic examinations of coal how far and in what ways the grouping of coal by types depends on differences in the kinds of plant material from which it was formed and on the conditions of its accumulation, or how far the special characters or qualities of coal of any type were determined by the nature and the state of the plate debris from which the coal was formed."
Description:
Report by the U.S. Bureau of Mines based on experiments performed in Pittsburgh, Pennsylvania to study mine gases. Findings in this bulletin include descriptions of the experiments and equipment used: "The first part of this report deals with the methods used by the bureau in the collection and examination of the various mine gases; the latter part discusses the bureau's methods of sampling and examining natural gas" (p. 5).
Description:
From Introduction: "Therefore the method of taking and preparing samples for shipment to the laboratory has been given fully as much care as the making of the analyses and tests, and a general plan of collecting samples fairly representative of the delivered coal has been evolved through various modifications and improvements based on experience and increased knowledge of the physical and chemical characteristics of the various coals that are purchased by the Government. The method that is in g…
