3/1/1998 - Peer reviewed journal articlesMine trailing cables operated above safe thermal limits can cause premature insulation failure, increasing electrocution and fire hazards. This paper describes an approach to measuring temperatures within reeled cable under dynamic test conditions.
-
11/28/2016 - Contracts and cooperative agreementsA contract to (1) conduct absolute pressure measurement and recording in both non-permissable and permissable areas of a coal mine and (2) explore methane gas cloud detection, measurement, and visualization.
-
7/19/2016 - Contracts and cooperative agreementsA contract to create an advanced mine-wide distributed monitoring system utilizing a low power intrinsically safe fiber optic backbone for improving ventilation and gas and temperature monitoring in underground mines.
-
6/1/2008 - Conference papersThis paper describes research conducted to compare the performance, including response time and accuracy, of selected instruments using infrared and catalytic sensors.
-
1/1/2000 - Peer reviewed journal articlesNIOSH has devised a passive means to detect overheating insulators on direct current systems.
-
1/1/1999 - Peer reviewed journal articlesA method is described to measure the conductor temperature of mine trailing cables during normal operation. The temperature is measured using an optical fiber located in the center of the metallic conductors.
-
8/1/1998 - Technology NewsNIOSH designed a passive device to detect overheating insulators on mine trolley/track haulageways.
-
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.
