1/1/2006 - Conference papersNIOSH's Office of Mine Safety and Health Research, in collaboration with MSHA Technical Support, has devised a prototype handheld device, Coal Dust Explosibitlity Meter (CDEM), to assess the potential explosibility of a coal and rock dust mixture.
-
3/1/2005 - Conference papersNIOSH used ground-penetrating radar (GPR) technology to determine if each of three test mine seals were uniformly constructed. The results suggest that GPR could be used as a tool to evaluate mine seal characteristics and construction uniformity.
-
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.
-
9/1/2002 - Information CircularsThis paper discusses a technique developed in partnership with RAG Twentymile Coal Co., Oak Creek, CO, for incorporating employee participation at all levels in fire prevention and safe equipment operation training outside of traditional classrooms.
-
6/1/2001 - Conference papersA project to evaluate the South African bagged stone dust explosion barrier was successfully completed at the NIOSH Lake Lynn Experimental Mine.
-
8/1/2000 - Information CircularsProvides a detailed description of a data collection instrument used to profile the fire prevention and response capabilities of a mine site.
-
5/1/2000 - Peer reviewed journal articlesExplosion characteristics such as the minimum explosible concentration and the rock dust inerting requirements were measured for various combustible dusts. The explosion resistance characteristics of seals was also evaluated.
-
10/1/1999 - NIOSH/USBM numbered publications, Training materialsThe first step to emergency preparedness is defining and analyzing hazards. Although all hazards should be addressed, resource limitations usually do not allow this to happen all at once.
-
6/1/1998 - Conference papersThere has been some improvement in overall mine fire preparedness. However, little data has been gathered on a site-by-site basis to determine what improvements might be made on a local level.
-
5/1/1998 - Reports of InvestigationsFull-scale testing and results are described for an automated system that continuously monitors the accumulation of coal dust in mine entries.
