Sampling and analysis method for measuring airborne coal

Airborne coal dust mass measurements in underground bituminous coal mines can be challenged by the presence of airborne limestone dust, which is an incombustible dust applied to prevent the propagation of dust explosions. To accurately measure the coal portion of this mixed airborne dust, the National Institute for Occupational Safety and Health (NIOSH) developed a sampling and analysis

Respiratory Disease Resurges Among Coal Miners

Oct 27, 2014In the late 1960s, concern about black lung disease led to new regulations of coal dust in mines. Photo: MSHA. Other researchers at the West Virginia Rural Health Research Center explain that while exact reasons for the increase in the prevalence of the disease aren't yet clear, evidence shows that smaller mines in certain areas of Appalachia have the greatest number of PMF cases.
