• Differential Pressure as a Measure of Particulate Matter Emissions from Diesel Engines
  4/1/2005 - Peer reviewed journal articles
  A diesel particulate matter analyzer capable of direct, real-time measurement of engine exhaust particulate is necessary to effectively institute source control technology currently being used on diesel equipment and to ensure that the control measures ...
• Sampling Results of the Improved SKC® Diesel Particulate Matter Cassette
  1/1/2005 - Peer reviewed journal articles
  Investigates the ability of the SKC DPM cassette to collect diesel particulate matter while segregating ore dust from the sample.
• Reducing Enclosed Cab Drill Operator's Respirable Dust Exposure with Effective Filtration and Pressurization Techniques
  1/1/2005 - Peer reviewed journal articles
  Discusses a cooperative research effort to lower respirable dust levels in an enclosed cab on an older surface drill at a silica sand operation. A number of modifications were incorporated into the drill's filtration and pressurization system, as well a...
• Submicrometer Elemental Carbon as a Selective Measure of Diesel Particulate Matter in Coal Mines
  10/1/2004 - Peer reviewed journal articles
  A monitoring method for diesel particulate matter was published as Method 5040 by the National Institute for Occupational Safety and Health (NIOSH).
• The Use of Light Scattering and Ion Chamber Responses for the Detection of Fires in Diesel Contaminated Atmospheres
  6/1/2002 - Peer reviewed journal articles
  Experiments were conducted to determine the optical scattering properties of diesel particulate matter (DPM) and various combustion aerosols from both flaming and smoldering combustion sources at discrete angles of 151 and 301 in the forward direction...
• Using Proximate Analysis to Characterize Airborne Dust Generation from Bituminous Coals
  6/1/2002 - Peer reviewed journal articles
  The amount of airborne respirable dust generated from breakage of different coals varies widely. This research was conducted to identify the facets of airborne respirable dust liberation from the coal product.

  2/1/2002 - Peer reviewed journal articles
  This article summarized results of research conducted by the National Institute for Occupational Safety and Health (NIOSH) at its Pittsburgh Research Laboratory. The objective of this work was to determine the correlation between the mass (M) of respir...
• The Effects of Low Quartz Mass Loading and Spatial Variability on the Quartz Analysis of Surface Coal Mine Dust Samples
  9/1/2001 - Peer reviewed journal articles
  The objectives of this work are to 1) evaluate the performance of the P7 method on field samples of low quartz mass loadings, 2) evaluate the magnitude of dust mass spatial variability within an enclosed cab environment, and 3) estimate the subsequent p...
• Estimate of Technically Feasible DPM Levels for Underground Metal and Nonmetal Mines
  9/1/2001 - Peer reviewed journal articles
  A method was developed to estimate the average workplace concentration of DPM that could be expected from using the new lower DPM-emitting engines now being approved by MSHA.
• Airborne Dust Liberation During Coal Crushing
  6/1/2001 - Peer reviewed journal articles
  This paper describes laboratory experiments in a wind tunnel with a roll crusher to identify relationships among crushing parameters, product size, coal rank properties and airborne dust generation.
