DUST LIBERATION DURING CRUSHING coal mine workers is a shift average of 2.0 mg of airborne respirable coal mine dust per cubic meter of air (2.0 mg/m3 as defined by the Mining Research Establishment (MRE) Criteria) 7. MSHA also does not permit explosive accumulations of coal dust in the air of or on
generated showed no significant charge levels for the tested coal samples from mines A, Band C (slightly negative). The measured airborne dust levels (total and respirable dust) indicated that the highest dust concentrations were observed for crushing the coal from mine A. The coal from mine B generated the lowest dust concentrations.

Intense disintegration of coal is presented as a non-oxidative source of carbon monoxide evolution. On the basis of laboratory investigations, a mechanically activated decomposition of oxygen containing groups of coal structure was denoted as the main mechanism of carbon monoxide (CO) generation during coal crushing.
