• Description:
  Details of explosion tests in the Experimental mine before 1925 were given in Bulletins 56, 167, and 268, which covered consecutive periods of time. The nature of the work during the present period and the exigencies of publication have made it desirable to issue three bulletins dealing with subdivisions of the general problem of the explosibility of coal dust and the prevention of explosions in coal mines. The first of these was Bulletin 353, dealing with 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. Technical Papers 386 and 464 were issued during the present period. The former dealt with tests of dusts prepared from coals received from Utah, and the latter gave a summary of results to 1929. The results of other investigations of urgent nature whose conduct interrupted the progress of explosion tests from time to time were also published. The more important of these were an investigation of ventilation for vehicular tunnels, a study of friction factors for mine airways, and tests of the strength of mine stoppings constructed of plain concrete.
