• Survey of Noise in Coal Preparation Plants
  1/1/2007 - Peer reviewed journal articles
  Noise surveys were conducted in eight coal preparation plants. Results indicate that only workers who routinely spend a significant portion of their shift in the plants (away from the control rooms) are susceptible to overexposure from noise.
• Noise Exposure and Hearing Conservation in US. Coal Mines - A Surveillance Report
  1/1/2007 - Peer reviewed journal articles
  This study examines the patterns and trends in noise exposure documented in data collected by Mine Safety and Health Administration inspectors at U.S. coal mines from 1987 through 2004.
• Summary of Longwall and Continuous Miner Section Noise Studies in Underground Coal Mines
  11/1/2006 - Peer reviewed journal articles
  This report summarizes the results of noise surveys, consisting of full-shift worker noise exposure, time-motion studies, and equipment noise profiling for longwall and continuous miner sections in six underground coal mines.
• Limestone Mining: Is It Noisy or Not?
  10/1/2006 - Peer reviewed journal articles
  This article describes noise research conducted in limestone mines, detailing the equipment likely to cause worker overexposures, the occupations experiencing overexposures, and the implications for worker noise exposure reduction.
• Sound Power Level Study of a Roof Bolter
  1/1/2006 - Peer reviewed journal articles
  NIOSH initiated a study of a roof bolter to reduce noise exposure to mine roof bolter operators. When drilling into granite, it was found that wet drilling generated lower sound power levels and performed better than vacuum drilling.
• Working in Noise with a Hearing Loss: Perceptions from Workers, Supervisors, and Hearing Conservation Program Managers
  12/1/2005 - Peer reviewed journal articles
  This study outlines potential challenges regarding job safety and hearing conservation practices for noise-exposed, hearing-impaired workers.
• Administrative Controls for Reducing Worker Noise Exposures
  12/1/2005 - Peer reviewed journal articles
  This publication describes worker noise exposure surveys in coal mines and coal preparation plants, revealing that worker dosimetry, time-motion studies, and equipment noise profiling are important for effective use of administrative controls.
• Noise and Vibration Reduction of a Vibrating Screen
  1/1/2005 - Peer reviewed journal articles
  This paper reports on a cooperative study on vibrating screen noise conducted at a coal preparation plant. Rubber isolators were found to reduce sound levels by 1 dB and amped side plates reduced vibration levels on the screen sides by 1 to 7 dB(A).
