7/1/2005 - Conference papersLarge-scale explosion tests conducted within the multiple-entry section of NIOSH's Lake Lynn Experimental Mine (LLEM) are currently the only accepted test method for deeming a seal design suitable for use in U.S. mines. These explosion tests are labor-i...

6/1/2005 - Conference papersThis paper evaluates the effectiveness of remotely applied nitrogen-enhanced foam to aid in efforts to isolate and suppress a mine fire.
-
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.
-
10/1/2003 - Conference papersDiscusses the evaluation of a seal evaluation method, based on a hydrostatic pressure loading concept, for in-situ testing of seals in an operating mine.
-
2/1/2003 - Conference papersReports on NIOSH full-scale experiments to evaluate the explosion-resistant characteristics of several new seal designs for rapid deployment during mine emergencies.
-
2/1/2002 - Conference papersOver the years, more than 20,000 mine seals have been erected in underground coal mines in the United States. The National Institute for Occupational Safety and Health is conducting research to develop design guidelines, to investigate noninvasive tech...
