• Best Practices to Mitigate Injuries and Fatalities from Rock Falls
  8/1/2000 - Conference papers, Safety guidelines, tips, and checklists
  This paper presents an overview of the most significant ground control hazards facing today's mineworkers, as well as best practices to reduce these risks.
• Cross-Sectional Survey of Noise Exposure in the Mining Industry
  8/1/2000 - Conference papers
  Includes general information on the hearing loss problem in mining, a review of hearing protection used and noise regulations in mining, and other background materials.
• The Aging Workforce: An Emerging Issue in the Mining Industry
  8/1/2000 - Conference papers
  The Bureau of Labor Statistics estimates that the median age of the mining workforce is rising faster than the overall U.S. civilian labor force. The Mine Safety and Health Administration reports that the percentage of injured and ill workers who are 45...
• Field Assessment of Retrofitting Surface Coal Mine Equipment Cabs with Air Filtration Systems
  8/1/2000 - Conference papers
  Operator cabs on a front-end loader and a rotary rock drill were retrofitted with ceiling mounted heating/AC units and air filtration systems.
• Using the Point Load Test to Determine the Uniaxial Compressive Strength of Coal Measure Rock
  8/1/2000 - Conference papers
  This study involved extensive load frame and point load testing of coal measure rocks in six states. More than 10,000 test results from 908 distinct rock units were used to classify rock lithologies into categories and determine conversion factors.
• Development and Evaluation of a Training Exercise for Construction, Maintenance and Repair Work Activities
  8/1/2000 - Conference papers
  Recent studies have shown that miners performing construction, maintenance, and repair (CMR) work activities in the conduct of their jobs incur from 39 to 65 percent of all reported injuries in the mining industry. To address this issue, an interactive...
• The Forgotten Denominator: Pillar Loading
  8/1/2000 - Conference papers
  This paper addresses a deficit in pillar loading research by exploring the accuracy of empirical abutment load calculations using insight provided by an elastic overburden model, a laminated overburden model and field observations.
• Computer Modeling of Catch Benches to Mitigate Rockfall Hazards in Open Pit Mines
  7/1/2000 - Conference papers
  In a computer analysis of bench stability, bench-scale plane shears and tetrahedral wedges are simulated and stochastically analyzed to estimate the probability of retaining specified catch-bench widths.
• Remote Controls on an Agricultural Tractor for Performing ASAE/SAE Field Upset Tests
  7/1/2000 - Conference papers
  A standard Ford 4600 agricultural tractor was converted to remote control to perform ASAE/SAE field upset tests (rear rollover and side rollover). This paper discusses the engineering process to develop a remote-controlled tractor in determining the cri...
• Using the Internet to Train Emergency Command Center Personnel
  5/1/2000 - Conference papers
  Well-prepared personnel and an effective emergency response plan are essential components of any emergency command center. The National Institute for Occupational Safety and Health (NIOSH) is developing an Internet-based, computer simulation training...
