• Improving the Performance of Fan-Powered Dust Collectors in Stone-Cutting Applications
  6/1/2008 - Conference papers
  The objective of the research was to cost-effectively increase the air cleaning volume and improve dust capture efficiency of an off-the-shelf dust collector with a larger motor and blower.
• Miners' Views About Personal Dust Monitors
  2/1/2008 - Information Circulars
  This report summarizes a field study by NIOSH that documented the reactions of 30 miners at 4 underground coal mines concerning the use of personal dust monitors (PDMs) and how they make use of the information it provides.
• Closing the Door to Dust When Adding Drill Steels: Uni-directional Cab Filtration and Pressurization System Tested
  10/1/2007 - Peer reviewed journal articles
  During a recent NIOSH field evaluation of a newly designed filtration and pressurization system for an enclosed cab of a surface drill, it was determined that the drill operator's respirable-dust exposure was significantly increased during time periods ...
• Miners' Views about Personal Dust Monitors
  9/1/2007 - Peer reviewed journal articles
  This NIOSH paper documents coal miners’ reactions to the new Personal Dust Monitor (PDM), and how they make use of the information th PDM provides.
• Dust Control Practices for Underground Coal Mining
  9/1/2007 - Conference papers
  This paper summarizes existing dust control technologies routinely being used in underground coal mine operations, and provides a review of new controls that are being pursued.
• Water Separator Shows Potential for Reducing Respirable Dust Generated on Small-Diameter Rotary Blasthole Drills
  9/1/2007 - Peer reviewed journal articles
  Tests have been conducted by NIOSH on a newly designed device for smaller diameter drills that separates the water from the bailing air before it reaches the bit and thus provides the cost benefit of dry drilling while providing the benefit of wet drill...
• Reducing Respirable Dust Exposure of Workers Using an Improved Clothes Cleaning Process
  4/1/2007 - Peer reviewed journal articles
  A quick, safe, and effective method has been developed that allows workers to clean their dust laden work clothing periodically throughout the day.
• Performance of a Light Scattering Dust Monitor at Various Air Velocities: Results of Sampling in the Active Versus the Passive Mode
  1/1/2007 - Peer reviewed journal articles
  The Thermo personal DataRam (pDR) is an instantaneous sampler that uses light-scattering technology to provide relative measures of airborne respirable dust. The pDR can be used in active and passive modes to measure respirable dust levels.
• Emerging Technologies Control Respirable Dust Exposures for Continuous Mining and Roof Bolting Personnel
  6/1/2006 - Conference papers
  This paper discusses NIOSH studies evaluating the impacts of emerging technologies that may reduce dust exposures for continuous mining and roof bolting personnel. These technologies include use of a wet-head cutting drum on a continuous mining machine,...
• Impact of Fan Type for Reducing Respirable Dust at an Underground Limestone Crushing Facility
  6/1/2006 - Conference papers
  NIOSH researchers have demonstrated that mine-wide ventilation in large-opening stone mines can be improved by using low-pressure, high-volume propeller fans and constructing stoppings in key locations to direct and control airflow.
