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.
-
3/1/2019 - 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.
-
5/1/2012 - 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.
-
11/1/2009 - 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.
-
11/1/2009 - Conference papersFor horizontal vibrating screens, NIOSH testing indicates that the screen sides and feed box are dominant noise sources for the 250 Hz through 800 Hz one-third octave bands, while the electric motor is the most significant source for the 1 kHz band.
