Fuel-Briquetting Investigations, July, 1904, to July, 1912 (open access)

Fuel-Briquetting Investigations, July, 1904, to July, 1912

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 country. Bulletins presenting the results of these investigations have been periodically published but as supply has run out, the Bureau of Mines has decided to compile the most important facts of these bulletins in one volume along with the results of all other briquetting investigatins undertaken by the government from July 1, 1904, to July 1, 1912.

A Laboratory Study of the Inflammability of Coal Dust (open access)

A Laboratory Study of the Inflammability of Coal Dust

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."

Coal-Mine Accidents in the United States and Foreign Countries (open access)

Coal-Mine Accidents in the United States and Foreign Countries

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.
