Abstract
A Bureau of Mines procedure was developed for the analysis of volatile matter in airborne coal dust-rock dust mixtures prior to, and resulting from coal mine fires and explosions. Dust in the 10- to 20-mg weight range can be analyzed. Volatile matter is determined by a greatly scaled-down version of the empirical macroscale method used by the Bureau. The alkaline earth carbonates in the rock dust are dissolved in acid prior to the volatile matter determination of the residue, and the rock dust content is calculated from the analysis of calcium and magnesium by atomic absorption.
