Briquetting Tests of Lignite at Pittsburgh, Pennsylvania, 1908-9 : With a Chapter on Sulphite-Pitch Binder

Description: From Results of Briquetting Tests: "The results of the briquetting investigations conducted by the Government are expected to prove of considerable value, not only to the Government itself as the owner of extensive lignite deposits and largest single purchaser of fuel, but also to the people living in the the regions where lignite is found. The problem assumes still larger proportions when one realizes that the development of manufacturing industries in those regions depends upon the ability to obtain a cheap and satisfactory fuel. Although the results presented in this bulletin are not conclusive, they warrant the continuation of the investigators as soon as funds can be available for the purpose."

Stone Dusting or Rock Dusting to Prevent Coal-Dust Explosions, as Practiced in Great Britain and France

Description: 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."
