• Innovative Strategies for Mine Fire Preparedness
  6/1/1998 - Conference papers
  There has been some improvement in overall mine fire preparedness. However, little data has been gathered on a site-by-site basis to determine what improvements might be made on a local level.
• Mine Rescue Training Simulations and Technology
  5/1/1998 - Conference papers
  Reports on a series of mine rescue training exercises developed, conducted and evaluated by the National Institute for Occupational Safety and Health (NIOSH) in cooperation with the Pennsylvania Department of Environmental Protection, Bureau of Deep Min...
• Training to Improve Emergency Communication Skills
  5/1/1998 - Conference papers
  This paper introduces a method for teaching workers to communicate necessary information when giving or receiving emergency warning messages.
• Geotechnical Factors Influencing Violent Failure in U.S. Mines
  3/1/1997 - Conference papers
  Sudden, violent failures of rock around mine openings influence access, ventilation, and safety in both hard-rock and coal mines. The authors initiated a comprehensive study to develop predictive tools for assessing potential rock failure.
• Update on Mining Health and Safety Research
  1/1/1996 - Conference papers
  This address covers the areas of assessing the current status of the Mining Health and Safety Research Program and outlining the need and direction for continued research.
• Advances in Mine Emergency Communications
  4/1/1994 - Conference papers
  To address communicating while wearing an SCSR, two-way, FM radios were built in and improved mouthpieces were added to the SCSR to improve the ability to communicate. Prototypes we built and tested. Leaky feeder systems are also described.
• A Missing Component in Your Emergency Management Plans: The Critical Incident Stress Factor
  4/1/1994 - Conference papers
  In emergency management, the effects of stress on the performance of emergency personnel, typically have been ignored or regarded as too enigmatic to quantify. This paper discusses the concept of Critical Incident Stress in responders to emergencies. It...
• A Multiplexed Phone System for Small Mines
  7/1/1982 - Conference papers
  A new phone system was developed that provides eight full duplex communications channels over a single twisted shielded phone line, with no central switching station or line amplifiers. This system greatly simplifies installation and maintenance over th...
• Improved Rail Haulage Communications
  10/1/1978 - Conference papers
  An analysis is made of the trolley line as a communications line, and methods of improving its characteristics are discussed.
• Medium-Frequency Propagation in Coal Mines
  8/1/1978 - Conference papers
  Medium-frequency (MF) waves can propagate in a coal seam, bounded above and below by conducting rock, in an approximate transverse electro-magnetic (TEM) transmission-line mode with the electric field vertical and the magnetic field horizontal. The theo...
