• Integration of Vertical and In-Seam Horizontal Well Production Analyses with Stochastic Geostatistical Algorithms to Estimate Pre-Mining Methane Drainage Efficiency from Coal Seams: Blue Creek Seam, Alabama
  7/1/2013 - Peer reviewed journal articles
  An article detailing the extent to which it can be estimated that boreholes helped to degasify the Blue Creek coal seam in Alabama in advance of mining the seam.
• Real-time Diesel Particulate Monitor for Underground Mines
  6/1/2013 - Peer reviewed journal articles
  An article evaluating a commercial instrument developed based on NIOSH research for measuring EC concentrations in real time.
• Mutagenicity of Biodiesel or Diesel Exhaust Particles and the Effect of Engine Operating Conditions
  3/1/2013 - Peer reviewed journal articles
  A study of the mutagenic potential of diesel emissions from neat and blended soy-based fatty acid methyl ester (FAME) biodiesel compared to ULSD PM using different engine operating conditions and exhaust aftertreatment configurations.
• A noise control package for vibrating screens
  3/1/2013 - Peer reviewed journal articles
  NIOSH researchers have developed a suite of noise controls for vibrating screens consisting of constrained layer damping (CLD) treatments, a tuned mechanism suspension, an acoustic enclosure, and spring inserts.
• Visual feedback system to reduce errors while operating roof bolting machines
  2/1/2013 - Peer reviewed journal articles
  An experiment was conducted to explore coding and directional compatibility on roof bolting equipment and to determine the feasibility of a visual feedback system to alert operators of critical movements and workers in close proximity to the equipment.
• Effects of a diesel particulate filter regeneration process on aerosols in an underground mine
  12/1/2012 - Peer reviewed journal articles
  This study was conducted to evaluate the effects of a diesel particulate filter (DPF) regeneration process on the concentrations and size distributions of aerosols in an underground mine.
• Toward developing a new occupational exposure metric approach for characterization of diesel aerosols
  12/1/2012 - Peer reviewed journal articles
  In this study, the current exposure metric and two additional metrics, the surface area and the total number concentration, were evaluated by conducting simultaneous measurements of diesel ultrafine aerosols in a laboratory setting.
• NIOSH-Sponsored Research in Through-the-Earth Communications for Mines: A Status Report
  9/1/2012 - Peer reviewed journal articles
  National Institute for Occupational Safety and Health research aimed at demonstrating the feasibility of through-the-earth (TTE) wireless communication in mining.
• Improving stopping construction to minimise leakage
  7/1/2012 - Peer reviewed journal articles
  The research presented in this paper investigates the total leakage of a stopping, including air leakage through the stopping, at the stopping perimeter, and through the coalbed.
• Coal Workers' Pneumoconiosis Prevalence Disparity Between Australia and the United States
  7/1/2012 - Peer reviewed journal articles
  The mining industry and labor stakeholders together requested that the National Institute for Occupational Safety and Health (NIOSH) examine this issue, with the ultimate aim of reducing the rate of pneumoconiosis among U.S. coal miners.
