Method and apparatus for measuring surface density of explosive and inert dust in stratified layers
Patent
·
OSTI ID:5702009
In accordance with the present invention, a method and apparatus is provided for determining the surface density of explosive coal dust on top of a rock-dust substream or the surface density of inert rock dust on top of coal dust in underground mines using a dust accumulation meter. The levels of these dusts are determined by an in situ measurement of the optical relectivity of light from the combined coal dust/rock dust diffuse reflecting surface.
