• Benchmarking Longwall Dust Control Technology and Practices
  9/1/2011 - Peer reviewed journal articles
  Results from the NIOSH underground dust surveys and current longwall dust control technology and operating practices are discussed.
• Field Evaluation of Air-blocking Shelf for Dust Control on Blasthole Drills
  3/1/2011 - Peer reviewed journal articles
  Field tests confirm that an air-blocking shelf installed in the inside perimeter of a blasthole drill shroud substantially improves dust control. This modification reduced respirable dust by 66%–81% in the immediate vicinity of the shroud...
• Evaluation of Face Dust Concentrations at Mines Using Deep-Cutting Practices
  1/1/2011 - Reports of Investigations
  Dust surveys determined if deep-cut mining expose face workers to higher levels of respirable dust. Study findings indicate that levels on bolting faces did not appear to be affected by longer cycles associated with deep-cut mining practices.
• Evaluation of the Wet Head Continuous Miner to Reduce Respirable Dust
  2/1/2010 - Conference papers
  This paper describes field tests conducted by NIOSH to evaluate the effectiveness of a wet head continuous mining machine for reducing dust exposure for continuous miner operators.
• 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.
• Relationship Between Elemental Carbon, Total Carbon, and Diesel Particulate Matter in Several Underground Metal/nonmetal Mines
  2/1/2007 - Peer reviewed journal articles
  To evaluate how elemental carbon (EC), a surrogate of diesel particulate matter (DPM), predicts DPM, measurements of total carbon (TC) and EC were taken away from potential interferences in four underground metal/nonmetal mines during production.
• Evaluation of the SKC® DPM Cassette for Monitoring Diesel Particulate Matter in Coal Mines
  12/1/2004 - Peer reviewed journal articles
  A commercial version of the BOM impactor, called the DPM Cassette, was recently introduced by SKC®. Tests were conducted to evaluate the performance of the DPM Cassette for measuring diesel-source elemental carbon in the presence of coal dust.
• Characterization of Submicron-/Nano-scale Coal Dusts and Their Effects on Miners' Pneumoconiosis and Lung Cancer for Underground Coal Mines
  7/22/2024 - Contracts and cooperative agreements
  A contract with Pennsylvania State University to investigate the characterization of submicron-/nano-scale coal dusts and their effects on miners’ pneumoconiosis and lung cancer for underground coal mines.
• Respirable Coal Mine Dust: Mineral Content Sources, Monitoring and Control, and Building Capacity to Protect Miner Health
  2/28/2023 - Contracts and cooperative agreements
  A capacity-building contract with Virginia Tech University to better understand, control, and monitor mineral content in respirable coal mine dust.
• Respirable Coal Mine Dust (RCMD) Research: Characterization, Deposition, Monitoring, and Mitigation of RCMD and Capacity Building for Mine Health and Safety
  2/28/2023 - Contracts and cooperative agreements
  A capacity-building contract with the New Mexico Institute of Mining and Technology to perform respirable coal mine dust research, including characterization, deposition, monitoring, and mitigation of respirable coal mine dust.
