• The NIOSH Shield Hydraulics Inspection and Evaluation of Leg Data (Shield) Computer Program
  8/1/2002 - Conference papers
  A high percentage of longwall shields, which provide ground control in mines, operate well below the rated support capacity due to hydraulic malfunctions. NIOSH developed a computer program to identify shields not performing to rated specifications.
• 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.
• 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.
• A Spatial/Spectral Domain Microwave Coal Seam Imaging Sensor-Progress in Signal Processing
  7/1/1994 - Conference papers
  The paper, presents the results of roof coal thickness measurements in underground mines and rib coal thickness measurements in highwall mines. The microwave sensor described uses a unique spatial modulation scheme created by antenna motion, along with ...
• Propagation of EM Signals in Underground Mines
  1/1/1977 - Conference papers
  This report is a comprehensive summary of the results of the propagation measurements program conducted for the Bureau of Mines.
