Abstract: With the use of reliability-engineering and ergonomics theory, combined with mining-processing technology, the composition of the mine ventilation system and its characteristics, various factors which can impact the reliability of a mine ventilation system have been approached in detail.It indicates that the main factors which will impact the reliability of the mine ventilation network are the mine ventilation system, the harmful diagonal structure of the network and changes in ventilation network. The main factors which will impact the normal operation of the fan are the types of the fan, its inherent quality, installation, use and maintenance management, the placement environment of equipment, equipment operators, and the method of operation of the main fan. The effectiveness of mine ventilation control equipment changes the resistance in the network branch roadway, which will have a major impact on the system's reliability; the main underground mining process, such as haulage and hoisting, ore-pass draw, underground blasting and other activities, will cause a serious disturbance of air-flow to the mine ventilation system.

Key words: Mining ventilation system, Ventilation network, Ventilation control facilities, Ventilation management
