• A Summary of Fatal Accidents Due to Flyrock and Lack of Blast Area Security in Surface Mining, 1989 to 1999
  2/1/2002 - Conference papers
  This paper summarizes flyrock and blast area security fatalities from 1989-1999, examining causative factors. Accident data indicates that flyrock and lack of blast area security were primary causes of blasting related injuries in surface mining.
• Enhanced Surface Control for Roof and Rib Support
  8/1/2001 - Conference papers
  The goal of this project was to design and evaluate devices that can be installed with traditional primary or secondary roof supports, and that are easy to handle/install under temporary or previously supported roof.
• 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 Challenge of Enforcing Safety Rules in Remote Hazardous Work Areas
  3/1/1999 - Conference papers
  This conference paper presents some findings obtained from interviews with coal miners about why supervisors sometimes fail to enforce an important mine safety rule.
• Mine Rescue Training Simulations and Technology

• Geotechnical Factors Influencing Violent Failure in U.S. Mines
  3/1/1997 - Conference papers
  Sudden, violent failures of rock around mine openings influence access, ventilation, and safety in both hard-rock and coal mines. The authors initiated a comprehensive study to develop predictive tools for assessing potential rock failure.
• Update on Mining Health and Safety Research
  1/1/1996 - Conference papers
  This address covers the areas of assessing the current status of the Mining Health and Safety Research Program and outlining the need and direction for continued research.
• Advances in Mine Emergency Communications
  4/1/1994 - Conference papers
  To address communicating while wearing an SCSR, two-way, FM radios were built in and improved mouthpieces were added to the SCSR to improve the ability to communicate. Prototypes we built and tested. Leaky feeder systems are also described.
• A Multiplexed Phone System for Small Mines
  7/1/1982 - Conference papers
  A new phone system was developed that provides eight full duplex communications channels over a single twisted shielded phone line, with no central switching station or line amplifiers. This system greatly simplifies installation and maintenance over th...
