9/1/2002 - Technology NewsIn an effort to determine the effectiveness of multiple types of fire sensors for early and reliable mine fire detection, NIOSH has evaluated multiple sensors for early mine fire detection and nuisance signal discrimination.
-
6/1/2002 - Conference papersAn evaluation of multiple mine fire sensor types for nuisance alarm discrimination. The response of multiple fire sensor types to three small coal fires and three small conveyor belt fires in the presence of diesel emissions was evaluated.
-
4/1/2000 - Conference papersReport on the application of a neural-network program using mine sensor data to classify the type of fire.
-
10/1/1999 - Conference papersA series of four coal combustion experiments was conducted at the National Institute for Occupational Safety and Health, Pittsburgh Research Laboratory in the Safety Research Coal Mine to evaluate the response of optical and ionization smoke and CO sens...
-
6/1/1999 - Conference papersA report on a series of four coal combustion experiments conducted at the NIOSH (PRL) Safety Research Coal Mine (SRCM) to evaluate the response of fire sensors to a small 0.61 m square smoldering coal fire which transitions to flaming combustion in the ...
-
8/1/1998 - Conference papersSeveral 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.
-
5/1/1997 - Reports of InvestigationsA 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.
-
1/1/1996 - Reports of InvestigationsAn 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.
-
1/1/1995 - Reports of InvestigationsThe U.S. Bureau of Mines has constructed a smoke chamber and developed sensitivity tests for smoke detectors. Evaluation of six smoke detectors showed their potential for use as mine fire sensors or as part of a mine atmospheric monitoring system.
-
1/1/1995 - Reports of InvestigationsA report on research to determine the alarm times of smoke and carbon monoxide sensors and a point type heat sensor to slowly developing coal-conveyor belt fires.
