Sažetak
Ventilation systems play an essential role in underground works. To explore the interaction laws of two wings in a dual-wing diagonal ventilation system, methods of theoretical and case analyses were combined to propose a theoretical interaction equation (nonlinear) and approximate interaction equation (linear). The error between these equations was explored through a case study on Qianjiaying coal mine. The application conditions of the models were summarized and their errors were analysed. Results show that increase of air quantity at one wing causes the air quantity to decrease at the other wing in a diagonal ventilation system, and also leads to an increase of the total air quantity of the mine. The greater the resistance of the common airway, the greater is its influence. The absolute and relative errors of the west-wing air quantity change increase with the increase of east-wing air quantity change and increase of the common airway resistance. The absolute error does not reach 2.5 m3/s at most, but the increases in the magnitude of relative error are large. The absolute error of the total air quantity change increases with the increase of east-wing air quantity change; the relative error increases with the increase of the resistance of common airway when east-wing air quantity change is larger than 15 m3/s, and the relative error is less than 5%. The conclusions provide guidance for ventilation calculation.
