• A New Leak Test Method for Enclosed Cab Filtration Systems
  5/1/2012 - Reports of Investigations
  A new test method has been developed by the National Institute for Occupational Safety and Health (NIOSH) and Clean Air Filter (CAF) for quantifying the outside air leakage into environmental cab filtration systems.
• 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...
• 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.
• Continuous Miner Spray Considerations for Optimizing Scrubber Performance in Exhaust Ventilation Systems
  2/1/2010 - Conference papers
  This paper describes lab experiments to examine the effect of spray type, pressure, machine body blocking sprays, and scrubber airflow on dust and gas levels while using a 12.2 m (40 ft) exhaust ventilation curtain setback from the face.
• Key Design Factors of Enclosed Cab Dust Filtration Systems
  11/1/2008 - Reports of Investigations
  NIOSH experimentally investigated various factor effects on cab air filtration system performance.
• Reducing Dust Exposure from Contaminated Work Clothing with a Stand-Alone Cleaning System
  6/1/2008 - Conference papers
  An alternative method to the original system developed by NIOSH and Unimin Corp to provide for a stand-alone clothes cleaning system.
• Handbook for Dust Control in Mining
  6/1/2003 - Information Circulars
  This handbook describes effective methods for the control of mineral dusts in mines and tunnels. It assumes the reader is familiar with mining. The first chapter deals solely with dust control methods, regardless of the application. It is a brief tutori...
• Improved Float Dust Controls in Underground Coal Mines
  3/27/2023 - Research projects
  A project to reduce the risks associated with accumulations of combustible and explosive materials.
