Characterization of Particulates from Australian Underground Coal Mines

The re-identification of coal workers’ pneumoconiosis in Queensland 2015 has prompted improvements exposure monitoring and health surveillance Australia. potential consequences excessive to respirable dust may depend upon the size, shape mineralogical classes dust. Technology now advanced point that characteristics can be explored detail. This research collected samples from four operating underground mines Australia for characterization analysis using scanning electron microscopy (SEM) with energy dispersive X-ray (EDX). found multiple present their own particle size distributions. variation between appears have had a larger effect on distribution than differences mining processes within individual mines. due variations geologic conditions, seam or conditions.
