| The reliable ventilation system is the fundamental guarantee for the mine to produce safely. The reliability of mime ventilation may be divided into the reliability during disaster period and during normal period. In this paper, the reliability of mine during normal period is studied with graph theory, fundamental law of mine ventilation and reliability theory.The ventilation system of mine is composed with ventilation network ventilation machinery and ventilation buildings. According to the analysis of characteristics of mine ventilation system and the airflow regulations, the major factors which influence the airflow's stability of the ventilation system in mine are ascertained, and the evaluating indicator for reliability of the element factors to mine ventilation system are given in this thesis. The whole ventilation network is composed with many airways, and its reliability is based on the reliability of the airways. When studying the reliability of airways, not only whether the air quantity in the airway is in the appropriate...
