Real-time calculation and application of mine ventilation system environmental temperature

Based on the mine ventilation network calculation in this paper,all the mine ventilation system ambient temperature was real-time calculated and analyzed.First,different heat sources that effect the airflow temperature were classified and the basic calculation formula of heat sources was determined;second,according to compartmentalization of various types of roadway,different quality of the roadways was analyzed;finally,combined with the actual conditions of coal mines,ventilation system airflow and temperature parameters were calculated.These achievements can provid theoretical basis and reference value not only for the system's exploitation,reconstruction and development,but also for the design of ventilation system.
