What is a common method to assess the effectiveness of a ventilation system?

Conducting airflow and pressure measurements is a common method to assess the effectiveness of a ventilation system because it provides quantitative data that can be analyzed to determine whether the system is functioning as designed. These measurements help identify if the ventilation system is adequate for diluting and removing contaminants, maintaining safe oxygen levels, and ensuring comfortable conditions for workers. By evaluating both airflow rates and pressure differentials within the mine, operators can make informed decisions about any necessary adjustments or improvements to the ventilation system.

In contrast, asking workers for feedback may offer insights into perceived air quality or comfort but lacks the objectivity and accuracy that numerical measurements provide. Reviewing production rates could give indirect indications of system effectiveness but does not directly assess ventilation performance. Installing more fans without first analyzing airflow and pressure data might lead to unnecessary costs and could potentially exacerbate issues if the underlying problems with the ventilation system are not addressed.
