Szénpor

Szénpor refers to finely divided particles of coal. It is generated during various stages of coal mining, processing, and utilization, such as crushing, grinding, and combustion. The size of coal dust particles can vary significantly, with some being microscopic.

The presence of airborne coal dust is a significant concern in underground coal mines due to its potential to cause dust explosions. When suspended in air in sufficient concentrations and ignited by a spark or flame, coal dust can combust rapidly, leading to a powerful explosion. This phenomenon has historically been a major cause of fatalities in mining operations. Consequently, strict dust control measures are implemented in mines, including ventilation, water spraying, and the use of inert dust to reduce the risk of explosions.

Beyond mining safety, coal dust can also be an occupational hazard for mine workers and those involved in coal handling. Inhaling fine coal particles can lead to respiratory diseases, most notably coal workers' pneumoconiosis, commonly known as black lung disease. This condition is a form of CWP which is a progressive and irreversible lung disease caused by long-term exposure to coal dust.

In industrial settings where coal is burned for energy, such as in power plants, coal dust is a byproduct. While efforts are made to capture and manage this dust through filtration systems, some emission can occur. The environmental impact of coal dust relates to air quality and the potential for particulate matter pollution.
