• How to use the Coal Dust Explosibility Meter
  4/18/2013 - Training materials, Videos and multimedia
  This is a series of 5 videos explaining how to use the coal dust explosibility meter.
• Coal Dust Explosibility Meter Evaluation and Recommendations for Application
  8/15/2012 - Information Circulars
  This IC details a NIOSH investigation on the CDEM’s ability to accurately predict the explosibility of coal and rock dust mixtures. The conclusions support the field use of the CDEM to measure the explosibility of coal and rock dust mixtures.
• A New Leak Test Method for Enclosed Cab Filtration Systems
  5/1/2012 - Reports of Investigations
  A new test method has been developed by the National Institute for Occupational Safety and Health (NIOSH) and Clean Air Filter (CAF) for quantifying the outside air leakage into environmental cab filtration systems.
• DOSES - Determination of Sound Exposures
  2/4/2012 - PC software
  Software to simplify the record-keeping and analysis associated with time-motion studies and worker noise exposures, making it easier to identify and solve noise problems.
• Evaluating Portable Infrared Spectrometers for Measuring the Silica Content of Coal Dust
  1/1/2012 - Peer reviewed journal articles
  Miners face a variety of respiratory hazards while on the job, including exposure to silica dust which can lead to silicosis, a potentially fatal lung disease.
• Impact of Air Velocity on the Detection of Fires in Conveyor Belt Haulageways
  5/1/2011 - Peer reviewed journal articles
  This paper discusses the impact of ventilation airflow on alarm times of the smoke detectors and video cameras, CO levels, smoke optical densities and smoke obscuration, total smoke mass concentrations, and fire heat release rates.
• 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.
• Evaluation of Smoke Detectors for Use in Underground Mines
  2/1/2009 - Conference papers
  This report describes experiments and their results in determining the responses of a prototype smoke detector and a commercially available photoelectric smoke detector to smoke particles generated from various combustion sources.
• Field Evaluation of the Coal Dust Explosibility Meter
  10/1/2008 - Peer reviewed journal articles
  This paper describes the testing and reliability of results of a NIOSH developed Coal Dust Explosibility Meter (CDEM), a hand-held instrument that uses optical reflectance to measure the explosibility of a rock dust and coal dust mixture.
• Equivalency of a Personal Dust Monitor to the Current United States Coal Mine Respirable Dust Sampler
  1/1/2008 - Peer reviewed journal articles
  The work presented in this paper focuses on the relationship between the PDM and respirable dust concentrations currently measured by a coal mine dust personal sampler unit utilizing a 10 mm Dorr Oliver nylon cyclone.
