The purpose of this investigation was to develop and demonstrate the feasibility of techniques to determine selected properties of respirable coal mine dust. An approved underground horizontal elutriator that samples air at 36 cfm was designed, fabricated, and utilized in this study to collect respirable coal mine dust in three mines representing the Pittsburgh, Lower Freeport, and lower Kittanning coal seams. The methods that were developed for the characterization of particles are of doubtful value because of the large mass of dust required for the analyses. The preliminary results for dust from the three mines are useful in that they show the variation that can be expected in the properties of coal dust from different mines and in particle size fractions.
