Computational Fluid Dynamics (Cfd) Modeling And Validation Of Dust Capture By A Novel Flooded Bed Dust Scrubber Incorporated Into A Longwall Shearer Operating In A Us Coal Seam, Ashish R. Kumar
Theses and Dissertations--Mining Engineering
Dust is a detrimental, but unavoidable, consequence of any mining process. It is particularly problematic in underground coal mining, where respirable coal dust poses the potential health risk of coal workers’ pneumoconiosis (CWP). Float dust, if not adequately diluted with rock dust, also creates the potential for a dust explosion initiated by a methane ignition. Furthermore, recently promulgated dust regulations for lowering a miner’s exposure to respirable coal dust will soon call for dramatic improvements in dust suppression and capture.
Computational fluid dynamics (CFD) results are presented for a research project with the primary goal of applying a flooded-bed dust …
