• Effect of Longwall Face Advance on Spontaneous Heating in Longwall Gob Areas
  3/1/2010 - Peer reviewed journal articles
  In this paper, Computational Fluid Dynamics modeling of the effect of longwall face advance on the spontaneous heating of coals in a two-panel gob area using a bleeder ventilation system is presented.
• Modeling the Effect of Barometric Pressure Changes on Spontaneous Heating in Bleederless Longwall Panels
  3/1/2010 - Conference papers

• Performance Characteristics for Welded Wire Screen Used for Surface Control in Underground Coal Mines
  2/1/2009 - Conference papers
  The load-deformation characteristics and the load capacity of welded wire screen (roof screen) used to control ground fall were evaluated in the laboratory in a specially built test frame.
• 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.
• Numerical Study on Effects of Coal Properties on Spontaneous Heating in Longwall Gob Areas
  11/1/2008 - Peer reviewed journal articles

• Explosion Effects on Mine Ventilation Stoppings
  11/1/2008 - Reports of Investigations
  A joint MSHA and NIOSH study simulated actual coal mine explosion accidents to evaluate blast effects on typical U.S. mine ventilation stoppings, and presents construction and testing methods, explosion test data, and post-explosion conditions.
• A Numerical Evaluation on the Effects of Impermeable Faults on Degasification Efficiency and Methane Emissions During Underground Coal Mining
  9/1/2008 - Peer reviewed journal articles
