• Influence of Specific Surface Area on Coal Dust Explosibility Using the 20-L Chamber
  8/1/2018 - Peer reviewed journal articles
  A study using 20-L explosion chamber testing to examine the relationship between the explosion inerting effectiveness of rock dusts on coal dusts, as a function of the specific surface area of each component.
• Open-air Sprays for Capturing and Controlling Airborne Float Coal Dust on Longwall Faces
  1/1/2018
  An article presenting a study on the potential of open-air water sprays to reduce concentrations of airborne float coal dust, smaller than 75 µm in diameter, in longwall face airstreams.
• Characterization of Airborne Float Coal Dust Emitted During Continuous Mining, Longwall Mining, and Belt Transport
  9/1/2017 - Peer reviewed journal articles
  An article detailing field characterization studies performed by NIOSH to determine quantitatively the sources, types and amounts of dust produced during various coal mining processes.
• Comparison of Coarse Coal Dust Sampling Techniques in a Laboratory-simulated Longwall Section
  8/1/2017 - Peer reviewed journal articles
  In this study, a personal dust sampler was adapted for area sampling of coarse coal dust in high-velocity ventilation air and then tested alongside other dust samplers.
• Coal Workers' Health Surveillance Program (CWHSP)
  6/5/2017 - Research projects
  A project to maintain a Coal Workers’ Health Surveillance Program (CWHSP) designed to identify the incidence and progression of coal workers’ pneumoconiosis in all coal miners.
• Reducing Float Coal Dust: Field Evaluation of an Inline Auxiliary Fan Scrubber
  12/1/2016 - Peer reviewed journal articles
  This article by NIOSH discusses a prototype flooded-bed scrubber that was evaluated for float coal dust control in the return of a continuous miner section.
• Sensors for Automated Control of Coal Dust (SACCD)
  11/22/2016 - Contracts and cooperative agreements
  A contract to develop wireless sensor technology, using functional prototypes, that can continuously monitor the ratio of rock dust to coal dust throughout an underground coal mine.
• Respirable Dust Control for Surface Mines
  10/22/2016 - Research projects
  A project to reduce respirable silica dust exposure in surface mines through improved understanding of dust generation and transport, improvement of current control technologies, and development of new control technologies.
• Improving Coal Dust Explosion Hazard Assessment Strategies
  10/22/2016 - Research projects
  A project to eliminate coal dust explosions in underground coal mines.
• Improved Dust Control Methods for Longwall Mining
  10/22/2016 - Research projects
  A project to develop control technologies that will reduce the most common sources of respirable dust on the longwall face, which will in turn protect the health of mine workers on the longwall face.
