[Experimental assessment of coal and rock dust absorbing hazardous substances released from synthetic resins].
The experimental study evaluated the factors (temperature, mass of n polymer, time of sorption et al.) influencing coal and rock dust sorption of carbamide-formaldehyde, penopolyurethane monomers. The atmosphere of coal mines was proved to be contaminated during the extraction by multiple-component mixture, where the volatile monomers are gaseous, vaporous or absorbed by the dust particles.
