5/1/2009 - Conference papersThis study shows a very good agreement between observations of partially burnt coal particles under a scanning electron microscopy (SEM) and floor dust samples, collected and analyzed using the alcohol coking test and SEM, to estimate flame travel.
2/1/2009 - Conference papersNIOSH has initiated a seals research program with collaborators from Safety in Mines Testing and Research Station (SIMTARS) in Australia, West Virginia University (WVU), the Naval Research Laboratory (NRL), and U.S. Army Corps of Engineers (USACE).
Use of Occupational Ethnography and Social Marketing Strategies to Develop a Safety Awareness Campaign for Coal Miners12/1/2008 - Peer reviewed journal articlesThis article describes how occupational ethnographic techniques provided insights needed for "new product development."
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.
7/1/2008 - Conference papersThis paper reviews 11 prevention control techniques for coal mine bursts.
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.
