• Reducing Enclosed Cab Drill Operator's Respirable Dust Exposure at Surface Coal Operation With a Retrofitted Filtration and Pressurization System
  2/1/2002 - Conference papers
  This report discusses a cooperative research study performed on a surface drill retrofitted with a new pressurization and filtration system. Respirable dust concentrations were substantially reduced from 0.64 mg/m3 during pre-testing to 0.05 mg/m3 duri...
• 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...
• Current NIOSH Dust Control Research for Noncoal Surface Mines
  9/1/2001 - Conference papers
  This report focuses on two areas of research to lower miners' exposure to respirable dust at surface operations. These areas deal with enclosed cabs methods to lower dust levels at surface drills.
• Laboratory Testing To Quantify Dust Entrainment During Shield Advance
  6/1/2001 - Conference papers
  A series of controlled laboratory tests were conducted in a test stand simulating shield dust entrainment to evaluate changes in airborne respirable dust levels at different air velocities.
• Laboratory Evaluation of a Canopy Air Curtain for Controlling Occupational Exposures of Roof Bolters
  6/1/2001 - Conference papers
  Testing at NIOSH assessed the effectiveness of a canopy air curtain for controlling occupational exposures to respirable silica and coal dusts.
• Test Report on the Machine-Mounted Continuous Respirable Dust Monitor
  6/1/2001 - Conference papers
  The machine-mounted continuous respirable dust monitor (MMCRDM) is a fixed-location area sampling device developed for possible use at the working face of an underground coal mine. decades. Recently, an extensive series of laboratory and underground tes...
