• Jarring/Jolting Exposure and Musculoskeletal Symptoms among Farm Equipment Operators
  9/1/2008 - Peer reviewed journal articles
  The objectives of this study by NIOSH were to assess driver whole-body vibration (WBV) exposures and recommend interventions to reduce the risk of back-related injuries, particularly relative to vehicle jarring/jolting.
• An Expanded Model for Predicting Surface Coal Mine Drill Respirable Dust Emissions
  9/1/2008 - Peer reviewed journal articles
  The focus of this work is drill shroud dust leakage and the relationships of various drill parameters on this leakage.
• Evaluation of the Relative Importance of Coalbed Reservoir Parameters for Prediction of Methane Inflow Rates During Mining of Longwall Development Entries
  9/1/2008 - Peer reviewed journal articles
  This study presents a reservoir modeling approach to investigate the relative effects of different coalbed parameters on the migration of methane into development entries, and shows that this technique can be applicable to different coalbeds.
• Tell Me a Story: Using Stories to Improve Occupational Safety Training
  7/1/2008 - Peer reviewed journal articles
  This article discusses the social and cultural power of stories, and how they have been used to develop training for skilled blue-collar workers.
• Effects of Sampling Artifacts on Occupational Samples of Diesel Particulate Matter
  7/1/2008 - Peer reviewed journal articles
  In this study, NIOSH investigated the effects of adsorption artifact on diesel particulate matter samples from occupational settings.
• Laboratory and Field Evaluation of Dust Collector Bags for Reducing Dust Exposure of Roof Bolter Operators
  7/1/2008 - Peer reviewed journal articles
  This paper presents the results of NIOSH laboratory and field tests to evaluate the effectiveness of dust collector bags for reducing dust liberation and operator exposure from a roof bolter's dust collection system.
• A Company-Perspective Cost Analysis of the Personal Dust Monitor (PDM)
  7/1/2008 - Peer reviewed journal articles
  This paper presents the results of a hypothetical cost comparison analysis of the PDM with the current MSHA-required coal mine dust personal sampling unit (CMDPSU).
• Field Observations and Numerical Studies of Horizontal Stress Effects on Roof Stability in U.S. Limestone Mines
  6/1/2008 - Peer reviewed journal articles
  This paper describes a modeling approach that can be used as a tool to evaluate potential roof failure and optimize the stability of room and pillar layouts.
• Three-Dimensional Time-Lapse Velocity Tomography of an Underground Longwall Panel
  6/1/2008 - Peer reviewed journal articles
  This paper describes the 3D velocity tomograms that were generated to image the stress redistribution around an underground coal longwall panel to produce a better understanding of the mechanisms that lead to ground failure, especially rockbursts.
• Coal Dust and Methane
  6/1/2008 - Peer reviewed journal articles
  This article describes the Coal Dust Explosibility Meter (CDEM), a hand-held instrument developed by NIOSH, which uses optical reflectance to measure the explosibility of a rock dust and coal dust mixture, which is now commercially available.
