Abstract
Extensive use of diesels in the mining industry has given rise to questions concerning the exposure of miners to diesel aerosol emissions. Answering such questions accurately depends on the type of mine and the measurement methods that can be employed. In metal and nonmetal mines, measurement of the carbonaceous diesel particulate fraction of respirable dust aerosol is accomplished using common sampling techniques and laboratory analysis. In coal mines, measurement is complicated by the carbonaceous nature of the coal. In such cases, special sampling and analytical techniques must be used to distinguish between diesel and respirable coal dust aerosol. The objective of this Bureau of Mines paper is to review some of the techniques that can be used to measure the diesel particulate fraction of respirable aerosol in the mine environment. In addition, the regulatory requirements for respirable dust in U.S. mines and the physical and chemical characteristics of diesel aerosols are reviewed in the larger context of ambient aerosol in the mine. Current regulatory and experimental measurement protocols for respirable mine aerosols are discussed. These include the use of filtration, inertial impaction, and optical detection methods. In each case, the methodology is evaluated for the information that can be derived from the technique about the diesel fraction of the measured aerosol. Concluding the paper are recommendations on the use of dichotomous samplers to derive qualitative information on exposure to diesel aerosol in a mine. Also discussed are some of the Bureau's current research plans with regard to measurement of diesel emissions aerosol.
