When an underground coal mine ventilation system works in normal condition, the

airflow distribution remains in basically steady state conditions. Any significant

abnormal airflow quantity occurring in an airway could indicate that there are certain

hidden problems in the mine ventilation system. If such problems are left unattended

and uncorrected, they may result in a domino effects, or even severe problems. It is

necessary to identify the causes for the abnormal airflow quantity and eliminate hidden

troubles immediately. In this paper, the methodologies for recognizing abnormal airflow

quantity and for tracking its causes are introduced. A computer program implementing

the methodologies is demonstrated also.
