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."

It must recognized that no standard laboratory method of carbonization, even on a large unit, can yield results that exactly duplicate those obtained in ovens and retorts. The commercial results vary with the type of oven or retort. Allowance must be made for such differences in interpreting the BM-AGA test results in terms of commercial plants."

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

A Primer on Explosives for Coal Miners
From Introduction: "Much of the information in this primer has been obtained from experiments conducted by the technologic branch of the United Sates Geological Survey at the mining experiment station at Pittsburgh, Pa. These investigations have shown the recent development of a new type of short-flame explosives, which can be used with greater safety than black powder in mines where there is dangerous gas or inflammable dust, because the flame from the explosion of black powder lasts from 2,500 to 3,500 times as long does the flame from these newer explosives and is therefore more likely to ignite the gas or dust in such mines."
