Investigation of physics of adhesion of coal aerosols.

NTIS: PB/240-617 :1-58
The purpose of this study was to establish the adhesive properties of coal and rock dust to coal substrates. The results show that both particle electrical charge and substrate orientation have little effect on adhesion of dust compared with relative humidity and surface roughness. The results also indicate that about half of the respirable dust sticks to coal surfaces with forces so high that the coal will fracture before the dust particle is removed.
