• Using Ground Penetrating Radar for Roof Hazard Detection in Underground Mines
  1/1/1996 - Reports of Investigations
  Ground penetrating radar (GPR) has been investigated by NIOSH for its potential to determine roof hazards in underground mines. GPR surveys were conducted at four field sites with accompanying ground truth to evaluate GPR for roof hazard detection.
• Effective Hazard Recognition Training using a Latent-Image, Three-Dimensional Slide Simulation Exercise
  1/1/1995 - Reports of Investigations
  Experiments were conducted to determine if training using a latent-image, 3-D slide simulation exercise improved miners' ability to recognize roof and rib hazards. The training did significantly improve each miner's ability to recognize the hazards.
• A Fail-Safe Control System for a Mine Methane Pipeline
  1/1/1980 - Reports of Investigations
