9/1/2010 - Conference papersThis paper describes the first phase of research aimed at understanding explosion pressures that can develop in coal mines and the factors that lead to high explosion pressure and possible transition to detonation.
-
6/1/2010 - Conference papersThis paper discusses factors that could result in a potential undetected dust explosion hazard, when using current dust sampling procedures, in an area that otherwise appears to be adequately protected with rock dust.
-
11/1/2009 - Conference papersNIOSH has investigated several areas in which current practices may need to be updated to adequately protect mines against coal dust propagated explosions. Other closely related issues, such as rock dust testing methods, are also discussed.
-
9/1/2007 - Conference papersThis paper reviews how simultaneous application of three basic elements reduces the methane explosion hazard at coal mine working faces: (1) adequate ventilation, (2) regular monitoring of gas concentrations, and (3) elimination of ignition sources.
-
8/1/2006 - Conference papersNIOSH and MSHA conducted a joint survey to determine the range of coal particle sizes found in dust samples collected from intake airways of U.S. coal mines.
-
11/1/2013 - Conference papersA NIOSH study investigating the potential for lithium-ion battery thermal runaway from an internal short circuit in equipment approved as permissible for use in underground coal mines.
-
9/1/2010 - Conference papersNIOSH conducted large-scale explosion experiments at the Lake Lynn Experimental Mine to investigate the inerting effect of limestone rock dust. Flame travel was measured using a conventional test and results were compared to a newer method.
-
3/1/2010 - Conference papersThe authors' goal is to summarize the totality of the USBM's explosives and blasting research.
-
2/1/2010 - Conference papersA discussion of the NIOSH-developed software suite for methane control and prediction (MCP) based on an artificial neural network (ANN) is presented in this paper.
-
1/1/2010 - Conference papersThis paper discusses several milestone events that show the progress of methane control research in underground coal mines.
