• Teaching Miners: Breaking the Barriers to Learning
  10/1/2003 - Conference papers
  Miners, like many skilled blue-collar workers, are not traditional learners. They have not always been successful in classroom-type settings, preferring to learn on the job in a hands-on environment.
• The Long-term Performance of Surface Support Liners for Ground Control in an Underground Limestone Mine
  8/1/2003 - Conference papers
  The purpose of this paper is to evaluate the preliminary findings of a long-term underground study of various types of surface support liners, and to examine installation practices that are critical for an effective liner material application.
• Root Causes of Groundfall Related Incidents in U.S. Mining Industry
  8/1/2003 - Conference papers
  This paper utilizes rock-fall-related incident narratives from the MSHA database for a taxonomic analysis, which identifies event root causes and provides future direction for corrective measures to reduce the probability of event occurrence.
• Recent National Institute for Occupational Safety and Health Research Using Ground Penetrating Radar for Detection of Mine Voids
  7/1/2003 - Conference papers
  This study indicates that it may be possible to use ground penetrating radar (GPR) for initial underground mine studies followed by directional drilling to accurately delineate the extent and position of adjacent abandoned mine workings.
• Judgment and Decision Making Under Stress: An Overview for Emergency Managers
  6/1/2003 - Peer reviewed journal articles
  This paper discusses human judgment and decision making under stress. The authors assert that stress is one of the factors that decision makers must contend with in most life-or-death situations.
• Technology News 501 - Measuring Very Low Air Velocities in Underground Metal/Nonmetal Mines
  1/1/2003 - Technology News
  Conventional anemometers (e.g., vane) are capable of accurately measuring air velocities only above 100 ft/min. This research investigated other anemometry technology to detect low air velocities in the range of 0-100 ft/min. Two different portable ultr...
• Safety Concerns Associated With the Use of Electrically Powered Haulage to Remove Workers from Mines During Main Fan Stoppages
  10/1/2002 - Conference papers
  The roles of main mine fans in underground mines are to induce airflow and continuously remove hazardous gases and dust. This paper concentrates on those mines having only one fan to provide ventilation needs.
• Practical Techniques to Improve the Air Quality in Underground Stone Mines
  10/1/2002 - Conference papers
  Overview of a variety of techniques and methods that can be used to improve the air quality in underground stone mines.
• The Introduction of Roof Bolting to U.S. Underground Coal Mines (1948-1960): A Cautionary Tale
  8/1/2002 - Conference papers
  The story of how roof bolting was implemented by the mining industry, but took so long to live up to its promise, is a fascinating example of the interaction between economics, technology, regulation, and science. It still has important lessons for today.
• Review of Technology Available to the Underground Mining Industry for Control of Diesel Emissions
  8/1/2002 - Information Circulars
  This report reviews the performance and applicability of technology for the control of emissions from diesel-powered equipment used in underground coal and metal/nonmetal mines.
