• Test Results of Collision Warning Systems for Surface Mining Dump Trucks
  5/1/2000 - Reports of Investigations
  Researchers at NIOSH tested a number of commercially available and experimental sensors that monitor obstacles in a vehicle's blind spots.
• Surface Haulage Truck Research
  9/1/1999 - Peer reviewed journal articles
  NIOSH studies have focused on off-the-shelf technologies that would enable mine haulage truck drivers to "see" objects and people behind and to the side of a moving vehicle. This paper discusses two types of systems currently available: proximity warni...
• Overview of Mine Fire Detection
  8/1/1998 - Conference papers
  Several experimental programs were conducted at the Pittsburgh Research Center to investigate the level of mine fire detection and alarm capability possible using state-of-the-art technology.
• Technology News 468 - Tests of Doppler Radar Technology for Haulage Truck Backup Alarms
  12/1/1997 - Technology News
  Current innovations in Doppler radar technology have led to suggestions by several institutions and manufacturers that new backup alarm systems are available that can replace or augment warning systems for backing operations on large haulage vehicles.
• Evaluation of a Signaling and Warning System for Underground Mines
  5/1/1997 - Reports of Investigations
  A report evaluating a wireless signaling and warning system for underground mines applicable to both coal and non-coal mines. A TeleMagnetic Signalling Systems wireless ultra-low-frequency electromagnetic signaling system was installed and tested.
• Comparative In-Mine Evaluation of Carbon Monoxide and Smoke Detectors
  1/1/1996 - Reports of Investigations
  An evaluation of the comparative responses of five types of commercially available smoke detectors and a diffusion-mode CO detector under normal and reduced airflow conditions.
• One-Way Fire Warning Alarm System for Underground Mines
  7/1/1990 - Conference papers
  An ideal fire warning alarm system for underground mines would be low cost, convenient, fast, reliable, and able to warn all underground workers. The U.S. Bureau of Mine devised a one way communication system employs a large loop antenna and transmitter...
