  5/1/2004 - Conference papers
  Provides guidelines for more effective use of the ultrasonic anemometer.
• Advances in Proximity Detection Technologies for Surface Mining Equipment
  5/1/2004 - Conference papers
  Technology is available to assist off-road dump truck drivers in monitoring blind spots near their equipment. NIOSH is evaluating systems based on radar, GPS, RF tags, and cameras.
• A Study of Heat Stress Exposures and Interventions for Mine Rescue Workers
  2/1/2004 - Conference papers
  A study of heat stress exposures among mine rescue workers in underground mines. Investigating several engineering controls, such as cooling the air inhaled by rescuers through an apparatus, wearing cooling vests, and supplying thru the CCBA.
• Video Motion Detection for Real-Time Hazard Warnings in Surface Mines
  2/1/2004 - Conference papers
  A surveillance system using low-cost video cameras and computer software from the security industry was tested for effectiveness in monitoring mine slopes and providing real-time warning of rock falls.
• The Relationship of Roof Movement and Strata-Induced Microseismic Emissions to Roof Falls
  2/1/2004 - Conference papers
  This paper examines the capabilities of convergence and microseismic monitoring systems to better understand roof rock failure mechanics and anticipate falls. Understanding these techniques is critical in developing effective ground control strategy.
