• Evaluation of the Approach to Respirable Quartz Exposure Control in U.S. Coal Mines
  2/1/2012 - Peer reviewed journal articles
  The performance of the current regulatory approach was found to be lacking due to the use of a variable property - quartz content in airborne dust - to establish a standard for subsequent exposures.
• 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...
• The Impact of Black Lung and a Methodology for Controlling Respirable Dust
  12/1/2020 - Peer reviewed journal articles
  An article discussing the impact of coal workers’ pneumoconiosis, commonly known as black lung, and a general methodology for controlling respirable dust in underground coal mines.
• Design of a Water Curtain to Reduce Accumulations of Float Coal Dust in Longwall Returns
  7/1/2020 - Peer reviewed journal articles
  A study to determine the optimal configuration of a water curtain developed to reduce float coal dust in mine airways.
• Forty Years of NIOSH/USBM-developed Control Technology to Reduce Respirable Dust Exposure for Miners in Industrial Minerals Processing Operations
  6/1/2020 - Peer reviewed journal articles
  An article highlighting a number of effective dust-control techniques that have been developed and tested by NIOSH and the USBM since the implementation of the 1977 Mine Safety and Health Act.
• The Design of a Laboratory Apparatus to Simulate the Dust Generated by Longwall Shield Advances
  12/1/2019 - Peer reviewed journal articles
  This paper outlines the design parameters for a shield dust simulator.
• A Field Study of a Roof Bolter Canopy Air Curtain (2nd Generation) for Respirable Coal Mine Dust Control
  9/1/2019 - Peer reviewed journal articles
  This article describes NIOSH's testing of a 2nd generation roof bolter canopy air curtain (CAC) design at a Midwestern underground coal mine.
• Field Investigation to Measure Airflow Velocities of a Ram Dump Car Using Circular Routing at a Midwestern Underground Coal Mine: A Case Study
  8/16/2019 - Peer reviewed journal articles
  An article describing a field investigation completed to determine air velocities as well as operator dust exposure during shuttle car operation.
• Improving Protection Against Respirable Dust at an Underground Crusher Booth
  11/30/2018 - Peer reviewed journal articles
  An article describing a study at an underground limestone mine crusher booth that evaluated a filtration and pressurization system, two experimental prototype filters, and three cab pressure monitoring devices.
