What term refers to coal dust that is kept in suspension?

The term that refers to coal dust kept in suspension is float dust. This type of dust is particularly significant in mining environments, where it can accumulate in the air and pose health risks to workers. Float dust is defined as particles that remain suspended in the air for extended periods, allowing them to be inhaled and potentially leading to respiratory problems.

The behavior of float dust in the atmosphere is critical to mine safety and environmental monitoring. Understanding this concept is essential for implementing dust control measures in mining operations. Proper ventilation systems and dust suppression techniques can help reduce the concentration of float dust, thereby protecting workers and maintaining compliance with safety regulations.
