• 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.
• Improving Silica Dust Controls for Metal/Nonmetal Mining Operations in the United States
  4/1/2007 - Conference papers
  NIOSH researchers are improving protection provided by enclosed cabs on mining equipment, reducing dust generation from surface drills, reducing dust levels in iron ore operations, and developing a new method to clean dust from soiled clothes.
• 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.
• Lower Respirable Dust and Noise Exposure with an Open Structure Design
  11/1/2006 - Reports of Investigations
  This report discusses the evaluation of three types of product sizing silica sand structures: a masonry design, a steel-sided design, and an open structure design. An open structure design was superior from both a dust and noise standpoint.
• Lowering Respirable Dust at an Iron Ore Concentrator Plant Through Improved Ventilation Practices
  6/1/2006 - Conference papers
  A cooperative research effort was established to lower respirable dust levels in an iron ore grinding and concentrator plant. The most significant improvement was realized by changing the ventilation profile throughout the entire facility. Another succe...
• Dust Control on Longwalls: Assessment of the State of the Art
  6/1/2006 - Conference papers
  This paper presents an update on longwall dust control technology and practices in the U.S. It summarizes the results of NIOSH dust surveys conducted at longwalls throughout the country to document the types of controls that are being used and to quanti...
• The Effects of Water Spray Placement for Controlling Respirable Dust and Face Methane Concentrations
  4/1/2006 - Peer reviewed journal articles
  A series of laboratory evaluations examined the impact of water spray pressure, curtain setback distance, and external and underboom spray use for controlling respirable dust levels and sulfur hexafluoride tracer gas concentrations around a continuous m...
• Practical Techniques to Improve the Air Quality in Underground Stone Mines
  10/1/2002 - Conference papers
  Overview of a variety of techniques and methods that can be used to improve the air quality in underground stone mines.
• Silica Dust Sources in Underground Limestone Mines
  8/1/2002 - Conference papers
  The NIOSH Pittsburgh Research Laboratory is involved in research to identify silica dust sources and generation in underground metal/nonmetal mines. A summary of sampling procedures, resulting data, and methods being investigated to reduce silica dust w...
• Improving Silica Dust Control Through Targeted Research
  2/1/2002 - Conference papers
  NIOSH conducted a strategic planning effort to identify those areas in mining with the greatest research needs. In response, the Pittsburgh Research Laboratory (PRL) has implemented a multi-faceted research program to improve silica dust control for the...
