Meeting Dust Assessment Needs of an Automated Mining Industry.
NIOSH 1990 Sep:636-640
An overview was provided of a Bureau of Mines project that addressed improved monitoring and analysis of hazardous coal mine dusts. Major topics included real time dust level assessment, and dust component analysis. The project reviewed in this report had two primary goals. The first was to provide accurate real time measurements of the mass concentration of airborne respirable coal mine dust. Such capability was needed to provide feedback regarding dust levels to future automated dust control systems. The DAWN-A, a unique experimental apparatus for studying light scattered by dust particles, will be used to design an improved photometer. The second goal was to provide improved capabilities for respirable dust sample component analysis. The author states that such information will be needed to understand occupational lung disease and to better assess the hazards of workplaces. Fourier transform infrared spectroscopy has been selected as a promising technique to accomplish that goal.
