Mining and Preparing Domestic Graphite for Crucible Use

Description: From Prefactory Statement: "In this bulletin are presented the results obtained in the first two phases of the work outlined above. The bulletin is in two parts. The first part describes the methods of mining and milling used, suggests a standard method of sampling finished graphite, and describes a rapid and convenient method of analysis developed at the Pittsburgh station of the Bureau of Mines, to which has been assigned the analytical and microscopic work. The second part describes experiments on the concentration and milling of graphite, which were made at the Salt Lake City, Utah, station."

Structure in Paleozoic Bituminous Coals

Description: From Introduction: "To fill in a few of these gaps and to clarify some of the existing confusion is the aim of this paper. The immediate cause that led the author to investigate further the composition of coal and the origin and structure of its constituents was that when an attempt was made to discover the meaning of the coking and noncoking properties of a coal a more exact knowledge of the nature of the coal was required than was then available."

A Glossary of the Mining and Mineral Industry

Description: From Introduction: "This glossary is published by the Bureau of Mines as a contribution to the mining literature in the belief that it will fill a long-felt need. It contains about 20,000 terms; these include both technical and purely local terms related to metal mining, coal mining, quarrying, petroleum, and natural gas, and metallurgical works; names of useful, important, and common minerals and rocks; and geological terms. It presents in one comprehensive volume the available standard, technical terms relating to the mining and mineral industry, as well as provincialisms that have been or are now in use in English-speaking countries."

Oxides in Pig Iron: Their Origin and Action in the Steel-Making Process

Description: From Introduction: "In summarizing the evidence in the literature it is apparent that there is general agreement among furnace men on the existence of so-called "bad-iron." It is also evident that the existence of dissolved or occluded gases is not an explanation. The presence of suspended oxides has been proved, and at least one plausible explanation for their formation has been given."

Coal-Mine Fatalities in the United States, 1927

Description: Report compiled by the U.S. Bureau of Mines including statistics on fatalities in coal mines located in the United States as well as data regarding the various operations (e.g., number of miners employed and average production). The information is organized into tables for comparison and the text draws some overall conclusions in the summary.

Rock Bursts in the Lake Superior Copper Mines, Keweenaw Point, Michigan

Description: From Introduction: "The effect of rock pressure may be general and continuous disintegration and reduction in size of pillars of ore and rock left for the support of the workings, resulting in the collapse of hanging wall and the closing of stopes, drifts, and shafts, or the action may be sudden and violent and aside from seriously affecting the workings may present a real hazard to the operation of mines. The object in the preparation of this report is to add to the accumulated information and from the facts presented to make suggestions for protective measures to be taken when possible."

Extinguishing and Preventing Oil and Gas Fires

Description: From Introduction: " As the subject of oil and gas is necessarily broad, no attempt is made in this bulletin to treat it exhaustively; rather the bulletin aims to point out what has been done by operators in the past, and to describe various fire-prevention methods and fire-fighting apparatus which are being used or adopted by many of the larger oil companies. These methods and apparatus, it is believed, if universally employed by operators, will largely decrease the present enormous annual losses."

Coal-Mining Problems in the State of Washington

Description: From Introduction: "On account of extensive folding and faulting of the coal measures, mining in Washington presents many difficulties; therefore a description of the methods employed at some of the mines may be useful in planning operations in other regions, and is presented in this bulletin."
