Influence of particle size polydispersity on coal dust explosibility

Journal of Loss Prevention in the Process Industries, 2018
Abstract The effect of particle size polydispersity (σD) on coal dust explosibility was studied using a 20-L spherical explosion test apparatus. Four kinds of blends with a fixed median diameter (D50) of 95 μm but varying σD of 1.18, 1.70, 1.96 and 2.40, were prepared by mixing original coal samples with relative low σD.

Coal dust particle size survey of US mines

Journal of Loss Prevention in the Process Industries, 2007
Abstract The National Institute for Occupational Safety and Health (NIOSH) and the Mine Safety and Health Administration (MSHA) conducted a joint survey to determine the range of coal particle sizes found in dust samples collected from intake airways of US coal mines. The last comprehensive survey of this type was performed in the 1920s.
