• Reduced Workers’ Compensation Costs With Roof Screening
  9/1/2012 - Peer reviewed journal articles
  This paper quantifies potential savings in WC premiums due to a reduction in rock fall injuries after roof screening in Pennsylvania’s underground coal mines. Two hypothetical mines with realistic injury and WC premium estimates were used.
• Evaluation of the Approach to Respirable Quartz Exposure Control in U.S. Coal Mines
  2/1/2012 - Peer reviewed journal articles
  The performance of the current regulatory approach was found to be lacking due to the use of a variable property - quartz content in airborne dust - to establish a standard for subsequent exposures.
• Flammability of Wider Conveyor Belts Using Large-scale Fire Tests
  1/1/2012 - Peer reviewed journal articles
  This paper describes the results of recent experiments comparing results from using the BELT and the large-scale tests for six different belts.
• CO and CO2 Emissions from Spontaneous Heating of Coal Under Different Ventilation Rates
  10/1/2011 - Peer reviewed journal articles
  This study evaluated CO and CO2 emissions from spontaneous heating of a U.S. coal sample in an isothermal oven under different airflow ventilation rates from 100 to 500 cm3/min. Experiments were conducted at oven temperatures of 70, 90, and 100 °C.
• Benchmarking Longwall Dust Control Technology and Practices
  9/1/2011 - Peer reviewed journal articles
  Results from the NIOSH underground dust surveys and current longwall dust control technology and operating practices are discussed.
• Field Evaluation of Air-blocking Shelf for Dust Control on Blasthole Drills
  3/1/2011 - Peer reviewed journal articles
  Field tests confirm that an air-blocking shelf installed in the inside perimeter of a blasthole drill shroud substantially improves dust control. This modification reduced respirable dust by 66%–81% in the immediate vicinity of the shroud...
• Early Strength Performance of Modern Weak Rock Mass Shotcrete Mixes
  1/1/2011 - Peer reviewed journal articles
  A field-expedient test method and portable on site test equipment have been developed to measure shotcrete strength in the first six hours after application.
• Potential of Roof Screening to Reduce Workers' Compensation Cost
  12/1/2010 - Peer reviewed journal articles
  Many rock fall injuries can be prevented with roof screen, but many coal mines are reluctant to use it due to added cost. This study looked at potential savings in workers' compensation premiums due reduced rock fall injuries after roof screening.
• Machine-Related Injuries in the US Mining Industry and Priorities for Safety Research
  5/1/2010 - Peer reviewed journal articles
  Current research is addressing many machine safety issues in both underground and surface mining. This study identified some specific miner activities and machine types that may need further attention.
• Operating Speed Assessments of Underground Mining Equipment
  3/1/2010 - Peer reviewed journal articles
  This publication details the results of NIOSH studies to examine operating speeds based on usage and seam height.
