• Improved Dust Control for Bag Handlers
  4/1/2000 - Peer reviewed journal articles
  A recent report evaluating silica exposure levels in the metal/nonmetal mining industry noted that bag packaging and loading are some of the occupations at the greatest risk.
• A Review of Occupational Silica Exposures on Continuous Mining Operations
  1/1/2000 - Conference papers
  A Review of Occupational Silica Exposures on Continuous Mining Operations.
• Laboratory Evaluation of Pressure Differential-based Respirable Dust Detector Tube
  1/1/2000 - Peer reviewed journal articles
  Assessment of exposure to occupational dusts is a first step in reducing exposures to harmful dust concentrations. A new type of respirable dust sampler was developed and compared side-by-side to personal gravimetric samplers in the laboratory.
• Field Assessment of Control Techniques and Long-Term Dust Variability for Surface Coal Mine Rock Drills and Bulldozers
  9/1/1999 - Peer reviewed journal articles
  Airborne respirable dust surveys were conducted at six surface coal mines to investigate the effectiveness of dust control methods used on rotary rock drills and bulldozers.
• Investigation of Longwall Face Ventilation Air-Splitting Methods for Improved Dust Control
  3/1/1999 - Conference papers
  Two types of airflow splitting methods for improving longwall dust control were investigated by NIOSH's Pittsburgh Research Laboratory. These methods included a transducer mesh barrier and a staged spray barrier system.
• NIOSH Hazard Controls 27 - New Shroud Design Controls Silica Dust from Surface Mine and Construction Blast Hole Drills
  11/1/1998 - Hazard Controls
  Exposure to airborne respirable crystalline silica dust can lead to silicosis, a debilitating lung disease. On surface coal mining and construction sites, blast hole drills are notorious sources of airborne respirable dust that may contain significant a...
• Investigation of Coal Properties and Airborne Respirable Dust Generation
  10/1/1998 - Reports of Investigations
  Laboratory testing and results are presented where five bituminous coals were prepared and processed through a double roll crusher located in a low-velocity wind tunnel. The results indicate that a combination of several factors are associated with air...
• Full-Scale Testing of the Float Dust Deposition Meter
  5/1/1998 - Reports of Investigations
  Full-scale testing and results are described for an automated system that continuously monitors the accumulation of coal dust in mine entries.
• NIOSH Hazard ID 1 - Exposure to Silica Dust on Continuous Mining Operations Using Flooded-Bed Scrubbers
  8/1/1997 - Hazards IDs
  A study was conducted examining the risk of silica dust exposure in mine workers exposed to continuous miners equipped with flooded bed scrubbers.
• Technology News 463 - Machine-Mounted Continuous Respirable Dust Monitor
  7/1/1997 - Technology News
  A machine-mounted continuous respirable dust monitor is discussed that can accurately monitor, display, and record concentration levels of respirable coal mine dust in mines for extended periods.
