The explosibility of coal dust. Washington, DC: U.S. Department of the Interior, Bureau of Mines, Bulletin 20, 1911 Jan; :115-149
Although perhaps laboratory experiments had no great share in bringing about the general knowledge of the explosive character of coal dust, they are a valuable means of gaining information in advance of experiments carried out on a scale large enough to simulate mining conditions. The acceptance of the theory has come about only through such large-scale experimental work, which has shown conclusively that coal dust alone may be the cause of serious disasters or may propagate and prolong a comparatively harmless explosion caused from some other source, so as to produce a disaster extending through great areas. The object of this part of the report is to describe in some detail the work which has been done on a laboratory scale bearing on the question of coal-dust ignition and inflammation. Many of the experiments on a somewhat larger scale are excluded, but some such early experiments arc mentioned because of their historical interest and some of the most recent on account of their great importance in furnishing quantitative data.
