• Modified Tail Section Reduces Noise on a Continuous Mining Machine
  7/1/2011 - Peer reviewed journal articles
  Overexposure to noise remains a widespread, serious health hazard in the U.S. mining industries. Most other categories of illnesses and injuries associated with mining have improved, with the exception of hearing loss.
• Characterizing Exposures to Airborne Metals and Nanoparticle Emissions in a Refinery
  7/1/2010 - Peer reviewed journal articles
  An air quality survey was conducted at a precious metals refinery in order to evaluate worker exposures to airborne metals and to provide detailed characterization of the aerosols.
• Mining Haul Truck Cab Noise: An Evaluation of Three Acoustical Environments
  10/1/2009 - Peer reviewed journal articles
  This study examines noise exposure inside haul truck cabs during a typical workday involving normal operator practices, the effect of cab noise reduction features, the consequence of disabling noise controls, and the significance of maintenance.
• A Dual Sprocket Chain as a Noise Control for a Continuous Mining Machine
  9/1/2009 - Peer reviewed journal articles
  A dual sprocket conveyor chain for a CMM was examined both in the laboratory and in underground field studies to test the influence on lowering the sound power emissions of the chain conveyor of a CMM when compared to a standard chain.
• Noise Source Identification on a Continuous Mining Machine
  7/1/2008 - Conference papers
  In the Hemi-anechoic chamber of the Pittsburgh Research Laboratory noise source identification on a continuous miner was performed using phased array measurements and a frequency domain beamforming algorithm with Diagonal Removal.
• Identification of Noise Sources on Longwall Panels Using Multiple Time-Synchronized Dosimeters
  12/1/2007 - Peer reviewed journal articles
  This paper describes research designed to develop guidelines and test procedures for identifying all noise sources that are major contributors to the underground noise exposure of longwall coal mining system workers.
• Closing the Door to Dust When Adding Drill Steels: Uni-directional Cab Filtration and Pressurization System Tested
  10/1/2007 - Peer reviewed journal articles
  During a recent NIOSH field evaluation of a newly designed filtration and pressurization system for an enclosed cab of a surface drill, it was determined that the drill operator's respirable-dust exposure was significantly increased during time periods ...
