In ventilation systems, what does the term "stopping" refer to specifically?

The term "stopping" in ventilation systems specifically refers to the practice of sealing off sections of the mine. This process is integral to mine ventilation as it helps to control the movement of air in order to optimize airflow to where it is needed most while preventing the dilution of contaminated air and maintaining safety levels for workers. By effectively stopping certain sections, ventilation can be concentrated to ensure that fresh air is delivered to areas where miners are working, reducing the potential accumulation of hazardous gases or dust.

This sealing can be done using various materials to create barriers that direct airflow and manage air quality throughout the mine. Understanding this term is crucial for anyone involved in mine safety and ventilation because it directly impacts the overall effectiveness of the ventilation system in maintaining a safe working environment.
