The study on the influence of the natural ventilation pressure on the stability of the mines ventilation network

摘要：

The natural ventilation pressure would be produced because of the difference of the air density in the mine workings and the parameters of the mine ventilation network (such as flow,pressure and direction of the ventilation)would change accordingly.This may have some influence on the safety of the mines production.Therefore,it is necessary to quantitatively analyze the influence caused by the natural ventilation pressure on the mine ventilation networks.The mathematical model and quantitative relationship between natural ventilation pressure and parameters of the mine ventilation networks are achieved by using the theories of thermodynamics,fluid mechanics and ventilation network and are taken as the theoretical basis of safety evaluation,administration and flow adjustment of the ventilation system as well.
