• Engineering Factors in the Ventilation of Metal Mines
  1/1/1935 - NIOSH/USBM numbered publications
  In the belief that the quickest and cheapest method of obtaining effective ventilation of metal mines with regard to air conditions that promote efficiency, health, and safety is through more general application of the engineering factors involved rathe...
• Coal-Mine Ventilation Factors
  1/1/1929 - NIOSH/USBM numbered publications
  Ventilation has been a primary problem in coal mining since mines were first worked under sufficient cover to encounter inflammable or other noxious gases. This report describes testing done to determine how volumes of air be taken from the atmosphere
• Approved Explosion-Proof Coal-Cutting Equipment
  2/1/1920 - NIOSH/USBM numbered publications
  This bulletin deals with the general theory of protection from fire damp and also covers a detailed description of the apparatus that has been tested and approved.
• The Explosibility of Coal Dust
  1/1/1911 - NIOSH/USBM numbered publications
  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.
• A Primer on Explosives for Coal Miners
  1/1/1911 - NIOSH/USBM numbered publications
  An archived publication from the early days of the U.S. Bureau of Mines. This little book on explosives is published in the hope that it may aid in preventing accidents resulting from the improper use of explosives in mining.
