Coal Dust: What Is It, And Why Is It Dangerous?
2020-4-13 · Coal is an extremely brittle mineral, and both the extraction and refinement processes produce a fine powder known as coal dust. Coal is deliberately pulverized for use as fossil fuel, and this process also produces a substantial output of coal dust. Finally, mining, transportation and even the mechanical handling of coal can create coal dust.
