• Reducing Non-Contact Electric Arc Injuries: An Investigation of Behavioral and Organizational Issues
  11/1/2007 - Peer reviewed journal articles
  NIOSH investigated behavioral components associated with arc flash incidents in the mining industry and recommended interventions based on the findings.
• Ergonomic Interventions at Vulcan Materials Company
  11/1/2007 - Peer reviewed journal articles
  Many mining companies apply ergonomic principles, but it is done either informally and/or reactively. This paper discusses how Vulcan Materials Company applied ergonomic principles and the interventions implemented to reduce risk factor exposures.
• Measurement Method for Determining Absorption Coefficients for Underground Mines
  11/1/2007 - Peer reviewed journal articles
  This paper presents a method using a ray-tracing technique to determine absorption coefficients for underground mines. Absorption coefficients are determined and presented for octave bands from 63 Hz to 8 kHz.
• Role of Lubrication Oil in Particulate Emissions from a Hydrogen-Powered Internal Combustion Engine
  10/1/2007 - Peer reviewed journal articles
  The primary goal of this study was to investigate the formation of combustion-generated particles derived from lubrication oil in the absence of fuel-produced soot.
• Mine Face Ventilation: A Comparison of CFD Results Against Benchmark Experiments for the CFD Code Validation
  10/1/2007 - Peer reviewed journal articles
  To transfer CFD expertise to analyze and design a face-ventilation system, a comprehensive validation study of current CFD tools against mining-related benchmark experiments is required. This study was dedicated to the methane behavior in an empty (cont...
• 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 ...
• Miners' Views about Personal Dust Monitors
  9/1/2007 - Peer reviewed journal articles
  This NIOSH paper documents coal miners’ reactions to the new Personal Dust Monitor (PDM), and how they make use of the information th PDM provides.
• Numerical Analysis of the Influence of In-Seam Horizontal Methane Drainage Boreholes on Longwall Face Emission Rates
  9/1/2007 - Peer reviewed journal articles
  This study investigates different horizontal methane drainage borehole patterns, borehole lengths, and degasification times prior to and during panel extraction to evaluate their effectiveness in reducing methane emissions using a dynamic 3D reservoir m...
• Water Separator Shows Potential for Reducing Respirable Dust Generated on Small-Diameter Rotary Blasthole Drills
  9/1/2007 - Peer reviewed journal articles
  Tests have been conducted by NIOSH on a newly designed device for smaller diameter drills that separates the water from the bailing air before it reaches the bit and thus provides the cost benefit of dry drilling while providing the benefit of wet drill...
• A Comparison of Fatigue Failure Responses of Old Versus Middle-Aged Lumbar Motion Segments in Simulated Flexed Lifting
  8/1/2007 - Peer reviewed journal articles
  In this study, survival analysis techniques were used to compare fatigue failure responses of elderly motion segments to a middle-aged sample. This study also evaluates the influence of bone mineral content on cycles to failure.
