• Long-Term Stability of a Backfilled Room-and-Pillar Test section at the Buick Mine, Missouri, USA
  10/1/2009 - Peer reviewed journal articles
  Instruments remaining in a test section of a lead/zinc/copper room and pillar mine where pillar mining had taken place 14 years before were read to monitor long-term stability and quantify time dependent behavior in the mine roof and backfill.
• Effects of Diesel Exhaust Aftertreatment Devices on Concentrations and Size Distribution of Aerosols in Underground Mine Air
  9/1/2009 - Peer reviewed journal articles
  This paper summarizes the results of a study conducted to evaluate the effects that several types of DPFs, DFEs, and a DOC have on the concentration and size distribution of diesel aerosols in an underground mine.
• Forecasting Gob Gas Venthole Production Performances Using Intelligent Computing Methods for Optimum Methane Control in Longwall Coal Mines
  9/1/2009 - Peer reviewed journal articles
  In this paper, the total gas flow rates and methane percentages from 10 GGVs were analyzed. The results showed that the two-hidden layer model predicted total production and the methane content of the GGVs with more than 90% accuracy.
• Guidelines for Instructional Materials on Refuge Chamber Setup, Use, and Maintenance
  7/1/2009 - Information Circulars, Safety guidelines, tips, and checklists
  NIOSH has created this document with suggestions for developing manuals and educational materials concerning refuge chambers for miners.
• CFD Modeling of Spontaneous Heating in a Large-Scale Coal Chamber
  7/1/2009 - Peer reviewed journal articles
  This paper discusses a study in which a three-dimensional CFD modeling of spontaneous heating of coal, based on the U.S. Bureau of Mines (USBM) large-scale coal chamber tests, was conducted.
• Stability Mapping to Examine Ground Failure Risk: A Field Study at a Limestone Mine
  7/1/2009 - Conference papers
  This paper presents a description of geologic settings, mining conditions, rockmass characterization with geotechnical risk assessment, analysis, mapping, and control techniques used at an underground stone mine in Central Pennsylvania.

  5/1/2009 - Technology News
  Researchers with NIOSH have developed a training module to educate both new, inexperienced miners as well as veterans on important issues related to self-rescue and escape procedures.
• Escape From Farmington No. 9: An Oral History
  5/1/2009 - NIOSH/USBM numbered publications, Training materials, Videos and multimedia
  This video-based training module can be used to educate both inexperienced and veteran miners on important issues related to self-rescue and escape procedures.
• Degasification System Selection for U.S. Longwall Mines Using an Expert Classification System
  3/1/2009 - Peer reviewed journal articles
  This study describes the development of an expert classification system used as a decision tool which can be used for degasification system selection using site- and mine-specific conditions.
• Use of Pressure Swing Adsorption Technology to Inert Sealed Mine Areas with Nitrogen
  2/1/2009 - Conference papers
  This paper describes the effort to create a reliable in-mine mobile plant for extracting nitrogen gas from the mine atmosphere. The gas produced by this novel technology can be used to create an inert environment in sealed mine areas.
