• Estimated Sound Power Radiated by Surfaces on a Continuous Miner Tail Section Using Vibration Measurements
  6/1/2003 - Conference papers
  This paper identifies the most significant noise-radiating surfaces on a continuous miner tail section and examines the effects of three engineering noise controls.
• The Consequences of 'Leaky' Enclosures
  1/1/2002 - Peer reviewed journal articles
  Discusses design criteria for making a proper acoustical enclosure where a machine operator can safely and effectively work.
• Noise Exposure in Longwall Mining and Engineering Controls Research
  6/1/2001 - Conference papers
  This paper presents a general review by NIOSH researchers of noise induced hearing loss (NIHL), the status of NIHL in mining, the results of the longwall noise surveys, and a review of the longwall engineering controls research efforts.
• Cross-Sectional Survey of Noise Exposure in the Mining Industry
  8/1/2000 - Conference papers
  Includes general information on the hearing loss problem in mining, a review of hearing protection used and noise regulations in mining, and other background materials.
• Vibration Testing of Off-Road Vehicle Seats
  1/1/1993 - Reports of Investigations
  The U.S. Bureau of Mines, in conjunction with Carter Mining Co., conducted vibration tests of four off-road vehicle seats. The purpose of the tests was to determine which seat provided the best vibration attenuation under laboratory conditions.
• Adaptive-Noise-Cancellation Techniques for Through-the-Earth Electromagnetics: Volume III
  2/1/1984 - Contract reports
  An electromagnetic (EM) system for the location of trapped mine workers at coal-mine (300 m) depths has been developed.
• Noise Reduction of a Pneumatic Rock Drill
  11/1/1975 - Reports of Investigations
  Data are presented on the individual and combined effects of Bureau of Mines modifications on standard pneumatic rock drills in reducing noise.
• Noise Abatement of Pneumatic Rock Drill
  12/1/1974 - Reports of Investigations
  The principal emphasis of this Bureau of Mines report is on pneumatic drill noise control. Methods are suggested to reduce the noise level by complementing existing machines.
