• Rapid (Grab) Sampling During Full-scale Explosions - Microscopic and Analytical Evaluation
  1/1/1988 - Reports of Investigations
  The Bureau of Mines has developed a system using a high-speed electropneumatic mechanism for the rapid (grab) sampling of dusts and gases during an explosion to monitor pyrolysis-charring in coal particles and combustion of pyrolysis vapors.
• Triboelectric Effects on Polyethylene Methane Drainage Pipelines
  1/1/1986 - Reports of Investigations
  The Bureau of Mines performed laboratory experiments to evaluate the triboelectric effect of particulate-laden gas streams on polyethylene pipe at various velocity, humidity, dust-size, and dust-load conditions.
• Methane and Dust Control by Water Infusion: Pittsburgh Coalbed (Fairview, W. Va.)
  1/1/1972 - Reports of Investigations
  The effect of water infusion on the flow of methane and on the production of dust was investigated at an active face in the Pittsburgh coalbed. The average total flow of methane at the face decreased by approximately 79 percent, whereas the flow from th...
• First Series of Coal-Dust Explosion Tests in the Experimental Mine
  4/1/1913 - NIOSH/USBM numbered publications
  A USBM report that presents the results of the first series of coal dust tests conducted in the experimental mine, along with a description of the experimental mine and its establishment.
• AQE - Air Quantity Estimator
  12/8/2022 - PC software
  Use the Air Quantity Estimator to gauge the air quantity needed to dilute diesel particulate matter (DPM) in an underground large-opening mine. Now in 2.0!
• Best Practices for Dust Control in Metal/Nonmetal Mining
  5/1/2010 - Information Circulars, Safety guidelines, tips, and checklists
  This handbook was developed to identify available engineering controls that can assist underground and surface metal/nonmetal mining operations in reducing worker exposure to respirable silica dust.
• Best Practices for Dust Control in Coal Mining
  1/1/2010 - Information Circulars, Safety guidelines, tips, and checklists
  This handbook was developed to identify available engineering controls that can help the industry reduce worker exposure to respirable coal and silica dust.
• Technology News 514 - The Air Quantity Estimator (AQE): A New Computer Software Tool for Large-opening Mine Ventilation Planning
  3/1/2006 - Technology News
  A combination of engineering, administrative, and ventilation controls will eventually be required in many large opening mines in the United States to meet the regulatory DPM concentration limits. The AQE is a tool for mine planners to use to estimate s...
• Coal-Dust Explosion Tests in the Experimental Mine 1919 to 1924, Inclusive
  1/1/1927 - NIOSH/USBM numbered publications
  This report on the third series of coal-dust explosibility tests at the experimental mine near Bruceton, PA., about 12 miles from the Pittsburgh experiment station of the bureau, covers the years 1919 to 1924, inclusive.
• 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.
