of any non-volatile respirable dust. In addition to inert dusts [4], the method has been recommended for respirable coal dust. The method is biased in light of the recently adopted international definition of respirable dust, e.g., ≈ +7% bias for non-diesel, coal mine dust [5]. INTERFERENCES:
The operation of the CDEM-1000 is based on the difference in optical reflectance between the darker coal dust and the lighter inert rock dust in band samples taken from the mine surface. The mixture of coal dust and the lighter inert rock dust becomes lighter in color as the concentration of rock dust .
