Stone Dusting or Rock Dusting to Prevent Coal-Dust Explosions, as Practiced in Great Britain and France
From Introduction: "Coal dust as an agent of widespread explosions had been under suspicion, and watering to allay the dust was recommended by some mining engineers but the watering of coal-mine dust was adopted in comparatively few mines of the United States and Great Britain, and had not been introduced widely in any country except Germany. Rock dusting, another method of preventing explosions of coal dust, was early tested with success by the Bureau of Mines in its first gallery at Pittsburgh and, beginning in 1911, at the experimental mine, Bruceton, Pa."

Sources of Limestone, Gypsum, and Anhydrite for Dusting Coal Mines to Prevent Explosions
From Preface: "The writer began testing the rock-dusting method for the Bureau of Mines at the Pittsburgh gallery in 1909, and later continued such testing in the bureau's experimental mine, with favorable results. Beginning in 1911 the bureau issued reports recommending rock dusting as alternative to watering."

Essential Factors in the Formation of Producer Gas
From Introduction Scope and Purpose of Inquiry: "The Bureau of Mines, to which the testing and analyzing of fuels as carried on by the United States Geographical Survey has been transferred, is continuing producer-gas investigations at the testing station at Pittsburgh, Pa. Results of the gas-producer tests made at the coal-testing plant erected at St.Louis, Mo., and of a study of some of the problems that came up in the tests have been published by Geological Survey. Results of the tests made at Norfolk, Va., and Pittsburgh, Pa. and of further studies of particular problems, will be published by the Bureau of Mines."

The Use of Permissible Explosives
From Preface: "The present bulletin is printed as a supplement to Bulletin 17 and is intended primarily for coal miners, especially for those working in fields where inflammable gas or coal dust may cause disastrous mine explosions. The bulletin is issued by the Bureau of Mines in the hope that it may prove helpful in lessening accidents due to the use of explosives, and in particular may aid in preventing mine explosions, many of which have been caused by the use of improper explosives."

Recent Development of the Producer-Gas Power Plant in the United States
From Introduction: "A summary of the tests made at St. Louis and a resume of the conclusions to be drawn from the tests and from the opinions of gas-producer manufacturers on the status of the gas producer and gas engine was published in a Survey bulletin in 1907. As it is desirable to repeat much of the material that appeared in the former bulletin (now out of print), this presentation may be regarded as a revision of the previous one, although considerable information not previously available for publication has been added."

Physical Testing of Explosives at the Bureau of Mines Explosives Experiment Station, Bruceton, Pennsylvania
From Introduction: "The methods of making the physical tests of explosives recorded here are based upon the results of more than 20 years of experience of the staff of the explosives division of the Bureau of Mines at the Pittsburgh testing station and at its successor, the Explosives Experiment Station, Bruceton, Pa. The methods are described in unusual detail to permit repetition that will duplicate, as nearly as possible, the precise manner in which they have been performed in the past and to reduce differences in technique to a minimum."
