• 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...
• Status of Dust Control Technology on U.S. Longwalls
  2/1/1997 - Conference papers
  NIOSH conducted dust surveys at 13 longwalls operating throughout the U.S. and collected information to: identify current operating practices on these longwalls, identify the types of dust controls in use, etc.
• Silica...It's Not Just Dust
  1/1/1997 - NIOSH/USBM numbered publications
  This pamphlet provided information on what rock drillers can do to protect themselves from silica dust, which may cause silicosis. The role of exposure to silica dust in the development silicosis was discussed.
• Status of a Tapered Element, Oscillation Microbalance-Based Continuous Respirable Coal Mine Dust Monitor
  1/1/1996 - Peer reviewed journal articles
  In response to the Mine Safety and Health Administration's request, the U.S. Bureau of Mines investigated several sensor technologies for continuously monitoring respirable coal mine dust. One of these technologies is the tapered element, oscillating m...
• Technology News 447 - Dust Collector Discharge Shroud Reduces Dust Exposure to Drill Operators at Surface Coal Mines
  3/1/1995 - Technology News
  Dust collector discharge shrouds were used to reduce airborne respirable dust generated from emptying dry dust collectors on small truck-mounted drills at surface coal mines.
• Assessment of Airborne Dust Generated From Small Truck-Mounted Rock Drills
  1/1/1995 - Reports of Investigations
  Dust control modifications were implemented on small, truck-mounted rock drills at surface coal mines. The control techniques showed noticeable improvement in measured dust concentrations around the drills.
