• Use of a Directional Spray System Design to Control Respirable Dust and Face Gas Concentrations Around a Continuous Mining Machine
  12/1/2004 - Peer reviewed journal articles
  A laboratory study assessed the impacts of water spray pressure, face ventilation quantity, and line brattice setback distance on respirable dust and SF6 tracer gas concentrations around a continuous mining machine using a sprayfan or directional spray ...
• The Use of Light Scattering and Ion Chamber Responses for the Detection of Fires in Diesel Contaminated Atmospheres
  6/1/2002 - Peer reviewed journal articles
  Experiments were conducted to determine the optical scattering properties of diesel particulate matter (DPM) and various combustion aerosols from both flaming and smoldering combustion sources at discrete angles of 151 and 301 in the forward direction...
• Use of Occupational Ethnography and Social Marketing Strategies to Develop a Safety Awareness Campaign for Coal Miners
  12/1/2008 - Peer reviewed journal articles
  This article describes how occupational ethnographic techniques provided insights needed for "new product development."
• Use of Rocsil® Foam to Remotely Construct Mine Seals
  12/1/2008 - Peer reviewed journal articles
  This paper presents an overview of remote mine sealing technology, introduces the use of Rocsil® foam for remote mine seal installations, and offers a case study for the use of this rigid foam material to remotely construct a temporary in-mine.
• Using Dust Assessment Technology to Leverage Mine Site Manager-Worker Communication and Health Behavior: A Longitudinal Case Study
  1/1/2016 - Peer reviewed journal articles
  A study looking at how a dust assessment technology, the Helmet-CAM, was used to identify and encourage communication about potential problem areas and tasks on site that contributed to elevated exposures.
• Using Ergonomics To Enhance Safe Production At a Surface Coal Mine - A Case Study With Powder Crews
  10/1/2009 - Peer reviewed journal articles
  (NIOSH) researchers worked with powder crew members from the Bridger Coal Company to identify and rank routine work tasks based on perceived exposure to WMSD risk factors.
• Using Persuasive Messages to Encourage Voluntary Hearing Protection Among Coal Miners
  1/1/2005 - Peer reviewed journal articles
  This field study encouraged coal miners in WV and PA to engage in hearing protection behaviors. Responses from 307 coal miners showed that positive or neutral messages generated more self-reported hearing protection behaviors than negative messages.
• Using Proximate Analysis to Characterize Airborne Dust Generation from Bituminous Coals
  6/1/2002 - Peer reviewed journal articles
  The amount of airborne respirable dust generated from breakage of different coals varies widely. This research was conducted to identify the facets of airborne respirable dust liberation from the coal product.
• Using Software to Predict Occupational Hearing Loss in the Mining Industry
  3/1/2016 - Peer reviewed journal articles
  This article by NIOSH discusses a software program that estimates the loss of hearing ability caused by occupational noise exposures.
• Using the Coal Mine Roof Rating (CMRR) to Assess Roof Stability in U.S. Coal Mines
  8/1/2001 - Peer reviewed journal articles
  The CMRR quantifies defects in the rock mass and compiles a strength value used for engineering design. The CMRR has been applied to a number of ground stability problems. The CMRR procedure and some of these applications are described in this paper.
