• Horizontal Air Blocking Shelf Reduces Dust Leakage from Surface Drill Shroud
  2/1/2009 - Conference papers
  This paper presents the results of laboratory testing to determine if the installation of a horizontal air blocking shelf around the inside perimeter of a surface mining drill deck will improve dust capture.
• Horizontal Air-Blocking Shelf Reduces Dust Leakage from Surface Drill Shroud
  12/1/2008 - Peer reviewed journal articles
  This paper describes a recent research project initiated by NIOSH which identified improvement of the drill shroud design as one of its main objectives for reducing the exposure of surface miners to respirable dust.
• Faces of Black Lung
  8/18/2008 - Videos and multimedia
  'Faces of Black Lung' features two miners who share their stories and provide insight on how their lives have changed due to this devastating black lung disease.
• Effects of Sampling Artifacts on Occupational Samples of Diesel Particulate Matter
  7/1/2008 - Peer reviewed journal articles
  In this study, NIOSH investigated the effects of adsorption artifact on diesel particulate matter samples from occupational settings.
• The Effects of Ventilation Controls and Environmental Cabs on Diesel Particulate Matter Concentrations in Some Limestone Mines
  6/1/2008 - Conference papers
  In this investigative study NIOSH measured for sub-micrometer elemental carbon (EC) using two types of control technologies (ventilation and cabs) which are being implemented in limestone mines.
• Near Real Time Monitoring of Diesel Particulate Matter in Underground Mines
  6/1/2008 - Conference papers
  This paper describes a portable device developed by NIOSH for measuring levels of elemental carbon in real time.
• Improving the Performance of Fan-Powered Dust Collectors in Stone-Cutting Applications
  6/1/2008 - Conference papers
  The objective of the research was to cost-effectively increase the air cleaning volume and improve dust capture efficiency of an off-the-shelf dust collector with a larger motor and blower.
• Coal Dust and Methane
  6/1/2008 - Peer reviewed journal articles
  This article describes the Coal Dust Explosibility Meter (CDEM), a hand-held instrument developed by NIOSH, which uses optical reflectance to measure the explosibility of a rock dust and coal dust mixture, which is now commercially available.
• Field Measurement of Diesel Particulate Matter Emissions
  3/1/2008 - Peer reviewed journal articles
  This paper describes a quick and economic method which has been developed to estimate engine particulate emission levels.
• Miners' Views About Personal Dust Monitors
  2/1/2008 - Information Circulars
  This report summarizes a field study by NIOSH that documented the reactions of 30 miners at 4 underground coal mines concerning the use of personal dust monitors (PDMs) and how they make use of the information it provides.
