• 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.
• Pillar Stability Issues Based on a Survey of Pillar Performance in Underground Limestone Mines
  8/1/2006 - Conference papers
  A survey of pillar conditions was carried out at 21 operating limestone mines that use the room-and-pillar method. Pillar instability is most likely caused by unfavorable geological structures in pillars with width to height ratios of less than 1.5.
• 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.
• Expectations vs. Experience: Training Lessons Based Upon Miners' Difficulties when Using Emergency Breathing Apparatus
  4/1/2004 - Peer reviewed journal articles
  A field test of the NIOSH-developed training product "I Can't Get Enough Air" was conducted to determine if it led to improvements in miner's scores on a true/false test of their SCSR's functional capabilities and proper usage.
• Silica Dust Sources in Underground Metal/Nonmetal Mines - Two Case Studies
  2/1/2002 - Conference papers
  The ultimate goal of this research is to develop control technologies to reduce worker exposure to respirable silica dust. Dust surveys were conducted in an underground limestone and gold mine to investigate silica dust sources, generation levels, and ...
• 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.
• Using Ground Penetrating Radar for Roof Hazard Detection in Underground Mines
  1/1/1996 - Reports of Investigations
  Ground penetrating radar (GPR) has been investigated by NIOSH for its potential to determine roof hazards in underground mines. GPR surveys were conducted at four field sites with accompanying ground truth to evaluate GPR for roof hazard detection.
• Characterization of the 1986 Metal and Nonmetal Mining Workforce
  1/1/1988 - Data and statistics, Information Circulars
  A 1986 probability sample survey, mining industry population survey, to measure such employee characteristics as occupation; principal equipment operated; work location at the mine; present job, present company, and total mining experience.
• Methane Emission from U.S. Coal Mines in 1975, A Survey : A Supplement to Information Circulars 8558 and 8659
  1/1/1977 - Information Circulars
  This Bureau of Mines report tabulates methane emissions from U.S. Bituminous coal mines with daily emission rates of at least 100,000 cfd according to states, counties, and coalbeds. Most of the methane emitted is from mines in the Appalachian States. T...
• Geologic Investigations of Underground Coal Mining Problems
  1/1/1975 - Reports of Investigations
  Geological surveys were completed in six coal mines to study the overall geology of the coalbed, and to use the resulting data to evaluate the influence of the geological characteristics of the coalbed on safe and efficient coal extraction.
