• Elastic and Shear Moduli of Coal Measure Rocks Derived from Basic Well Logs Using Fractal Statistics and Radial Basis Functions
  12/1/2009 - Peer reviewed journal articles
  A new approach was tested and it was demonstrated that it could be used for prediction of elastic and shear moduli of coal-measure rocks with reasonable accuracy.
• How Does Limestone Rock Dust Prevent Coal Dust Explosions in Coal Mines?
  9/1/2009 - Peer reviewed journal articles
  This study investigates how limestone rock dust prevents the propagation of coal dust explosions by assessing its changes in chemical composition.

  The information in this report was used by MSHA and WVOMHS&T as supporting data in their analyses and investigative reports of the Sago Mine explosion.
• Frictional Ignitions in Underground Bituminous Coal Operations 1983-2005
  8/1/2009 - Peer reviewed journal articles
  NIOSH conducted a statistical study of available data regarding frictional ignitions in the United States from 1983 to 2005 to determine and define conditions controlling their occurrence.
• Reservoir Rock Properties of Coal Measure Strata of the Lower Monongahela Group, Greene County (Southwestern Pennsylvania), from Methane Control and Production Perspectives
  3/1/2009 - Peer reviewed journal articles
  This study presents reservoir and elastic properties of coal measure rocks in the Lower Monongahela Group in Greene County, southwestern Pennsylvania, with results that can be used as data sources for reservoir studies related to methane control.
• Progress Toward Improved Engineering of Seals and Sealed Areas of Coal Mines
  2/1/2009 - Conference papers
  NIOSH has initiated a seals research program with collaborators from Safety in Mines Testing and Research Station (SIMTARS) in Australia, West Virginia University (WVU), the Naval Research Laboratory (NRL), and U.S. Army Corps of Engineers (USACE).
• Current Trends in Reducing Ground Fall Accidents in US Coal Mines
  2/1/2009 - Conference papers
  Each of the electronic versions of the MSHA fatality reports since 1995 was analyzed in detail, categorized by the type of the ground fall hazard. The remainder of the paper is devoted to evaluating each of the five largest categories.
• Critical Review of Numerical Stress Analysis Tools for Deep Coal Longwall Panels Under Strong Strata
  2/1/2009 - Conference papers
