A Primer on Explosives for Coal Miners

Description: 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."

Explosion Tests of Pittsburgh Coal Dust in the Experimental Mine, 1925 to 1932, Inclusive

Description: From Introduction and Summary: "The first of these was Bulletin 353, dealing with the tests of rock-dust barriers; the second is the present paper, which reports tests made to determine the effect on the explosibility of Pittsburgh coal dust of altering conditions under which the tests were made; the third, dealing with tests of dust prepared from approximately 20 coals taken from beds in mines in different parts of the United States, will follow after the completion of testing in progress at the time of writing."

Structure and Propagation of Turbulent Bunsen Flames

Description: From Introduction and Summary: "In the assessments of research objectives after World War II it was brought out that little effort had yet been expended on an understanding of turbulent flames.The present report deals exclusively with a second stage of work which was carried out between November 1954 and August 1959. This summary report includes a few new data, but its chief purpose is to reorient the findings toward a better appreciation of what has been accomplished and what most profitably might be done in the near future."

Combustion of Coal and Design of Furnaces

Description: From Purpose and scope of Investigations: "The combustion investigations of bureau are carried on in two parts. One part is the study of the process of combustion in the fuel bed as affected by the rate of supplying air through the fuel bed, by the character of the fuel as regards structure and composition, by the thickness of fuel bed, by the method of feeding the coal and the air and by the method of heating the coal. The second part of the investigation is the study of the process of combustion of the gases and other combustible rising from the fuel bed in the combustion space, after a sufficient quantity of air has been added. The results of the study are given in this report."
