Mining Publication: The Explosibility of Coal Dust

This bulletin traces the growth in the belief in the explosibility of coal dust, summarizes the experiments and mine investigations that have established this belief, and gives the present (1911) status of preventive measures. It has been prepared in accordance with the provisions of the acts of Congress authorizing investigations relating to the causes of mine explosions, and contains references to and descriptions of experiments made at the Federal testing station at Pittsburgh, Pa. This station was inaugurated under the United States Geological Survey, and was transferred to the Bureau of Mines on the establishment of the latter on July 1, 1910.
