11/1/2008 - Peer reviewed journal articlesA computational fluid dynamics (CFD) study was conducted to model effects of coal properties on the potential for spontaneous heating in longwall gob (mined-out) areas.
12/1/2004 - Peer reviewed journal articlesA commercial version of the BOM impactor, called the DPM Cassette, was recently introduced by SKC®. Tests were conducted to evaluate the performance of the DPM Cassette for measuring diesel-source elemental carbon in the presence of coal dust.
Mapping of Compositional Properties of Coal Using Isometric Log-Ratio Transformation and Sequential Gaussian Simulation - A Comparative Study for Spatial Ultimate Analyses Data3/1/2019 - Peer reviewed journal articlesAn article on mapping the ultimate analyses parts of the Springfield coal from an Indiana section of the Illinois basin, using sequential Gaussian simulation of isometric log-ratio transformed compositions.
3/1/2013 - Peer reviewed journal articlesNIOSH researchers have developed a suite of noise controls for vibrating screens consisting of constrained layer damping (CLD) treatments, a tuned mechanism suspension, an acoustic enclosure, and spring inserts.
A provenance study of mineral matter in coal from Appalachian Basin coal mining regions and implications regarding the respirable health of underground coal workers: A geochemical and Nd isotope investigation5/1/2012 - Peer reviewed journal articlesThis study presents geochemical data produced from the analysis of coal and adjacent rock samples retrieved from coal mining regions in the U.S. to examine mineral matter provenance.
9/1/2011 - Brochures/flyers/pamphletsThe effect rocks and minerals have on our daily lives is not always obvious, but this book will help explain how essential they really are.
1/1/2011 - Peer reviewed journal articlesNIOSH is currently developing noise controls for horizontal vibrating screens.
1/1/2011 - Peer reviewed journal articlesThirteen coals of different rank were tested for ignition propensity in a 20-L explosion chamber simulating oxyfuel combustion gas conditions. The effects of coal type, coal concentration, O2 in CO2 atmospheres, and particle size were investigated.
Reservoir Engineering Considerations for Coal Seam Degasification and Methane Control in Underground Mines11/1/2009 - Conference papersThis paper demonstrates the applications of coal bed reservoir engineering and modeling techniques for optimizing and controlling methane emissions in longwall and continuous miner sections.
11/1/2009 - Conference papersIn this paper, computational fluid dynamics (CFD) modeling results for both bleeder and bleederless ventilation systems are presented and the difference between two systems is discussed.
