Research In Key Technology Of Mine Ventilation Simulation

Determination and calculation of frictional resistance coefficient is the key to the simulation of mine ventilation and foundation. In this paper, determination of the frictional resistance coefficient, calculation, simulation and other aspects are discussed. Analysis how to improve their determination, calculation, simulation accuracy and so on. As the frictional resistance coefficient in determination work consumed a certain manpower and material resources. And because the mine ventilation conditions complex, and data measured are not so accurate. Therefore, seek a way to resolve it. Author by the actual test of ventilation resistance should pay attention to proceeding summarized, Meanwhile, More than 6000 the actual test data are arranged. Application of BP neural network simulation algorithm and mathematical statistics method, multiple regression analysis of frictional system simulation. Analysis by two methods to different roadway which simulation methods should be applied more practical. To increase the frictional resistance coefficient accuracy and operability. The purpose is to reduce the manpower and material inputs, and for mine ventilation simulation system provides a more accurate basic data.
