Multiscale Correlation of Coal Mine Dust Physicochemical Properties and Wettability in Fully Mechanized Mining Faces

open access: yesEng
The wettability of dust is fundamental to its dispersion and control in mining operations. Current research, however, focuses largely on isolated properties, leaving the synergistic mechanisms of multi-scale factors-such as particle size, morphology, and surface chemistry-poorly understood.
