11/1/2008 - Conference papersThis work by NIOSH has modelled the impacts of borehole pattern and design and the effects of increasing face length on gob gas venthole performance.
3/1/2008 - Technology NewsThis briefly describes testing done to ignite methane-air in the presence of liquid hydrocarbons, and gives recommendations for limiting frictional ignition.
Analysis of Seismic Signatures from Gas and Dust Based Explosions at the Lake Lynn Experimental Mine2/1/2008 - Conference papersA seismic monitoring system at NIOSH's Lake Lynn Experimental Mine has monitored gas and dust-based explosions and impact tests. Results suggest that large unrestricted explosions can generate the same magnitude as small restricted explosions.
9/1/2007 - Conference papersThis paper discusses methods for protecting U.S. underground coal mines from explosions of methane gas and coal dust, and presents new research, such as the Coal Dust Explosibility Meter, a handheld device to directly measure coal dust explosibility.
9/1/2007 - Conference papersResearchers with NIOSH studied the electrical equipment ignition sources for the Brookwood and other disasters to develop recommendations for preventing similar disasters.
7/1/2007 - Peer reviewed journal articlesNIOSH's Pittsburgh Research Laboratory conducted a study of the explosibility of various metals and elemental dusts, focusing on explosion temperatures. The data will aid in evaluating explosion hazards in the minerals/metals processing industries.
7/1/2007 - Peer reviewed journal articlesNIOSH's Pittsburgh Research Laboratory (PRL) and the Mine Safety and Health Administration (MSHA) conducted joint research on post-explosion dust samples. The data will aid in future forensic investigations of accidental coal mine dust explosions.
6/1/2007 - Conference papersThis paper briefly describes the progress in mine safety in the United States, with emphasis on recent events that have followed since the explosion at the Sago Mine in January 2006. Legislation following the mine accidents in 2006 and areas of work car...
8/1/2006 - Conference papersNIOSH conducted a study of the explosibility of various metals and other elemental dusts dispersed in air to aid in understanding dust cloud combustion and in evaluating the explosion hazards in the minerals and metals processing industries.
8/1/2006 - Conference papersNIOSH and MSHA conducted joint research on dust explosions by studying post-explosion dust samples of high and low volatile bituminous coals collected from full-scale explosions at NIOSH's Lake Lynn Experimental Mine and from laboratory explosions.
