• Recommendations for a New Rock Dusting Standard to Prevent Coal Dust Explosions in Intake Airways
  5/1/2010 - Reports of Investigations
  This NIOSH report presents the results of extensive in-mine coal dust particle size surveys of dust samples collected from intake airways in 61 U.S. coal mines, representing all 10 MSHA bituminous Coal Mine Safety and Health Districts.
• From Scotia to Brookwood, Fatal US Underground Coal Mine Explosions Ignited in Intake Air Courses
  1/1/2009 - Peer reviewed journal articles
  NIOSH researchers studied U.S. underground coal mine explosions over a 30-year period to identify the ignition sources and locations responsible for severe explosions resulting in death, and provided recommendations for safer electrical design.
• Studying Intake Airway Pressurization by Ventilation Modeling and Leakage Evaluation
  2/1/2010 - Conference papers
  This paper discusses the role of ventilation modeling in evaluating primary escapeway pressurization in a three-entry development system to improve emergency escape in a coal mine using belt air.
• Investigation into the Practical Use of Belt Air at US Longwall Operations
  2/1/2009 - Conference papers
  This paper discusses the current ventilation practices regarding the use of belt air during gateroad development and longwall panel extraction.
• The Brookwood Disaster and Electrical Requirements for Hazardous (Classified) Locations
  9/1/2007 - Conference papers
  Researchers with NIOSH studied the electrical equipment ignition sources for the Brookwood and other disasters to develop recommendations for preventing similar disasters.
• Tracer Gas as an Aid in Mine Ventilation Analysis
  1/1/1974 - Reports of Investigations
  The Bureau of Mines has successfully used sulfur hexafluoride (SF6) as a tracer gas to measure mine air flows under conditions where conventional methods have failed. SF6 was employed experimentally to measure accurately recirculation of return into int...
