Reliability test of basic ventilation network data based on the simulation of ventilation network

There exist some error on the basic data of the mine tunnel according to determination of the ventilation resistance.The usual testing method of measured data can only be a number of tunnels for reliability test,not the whole of the mine ventilation network-based testing parameters.The testing method of this paper could test the basic data in the network-based data entry ventilation network software and then carry on the ventilation network simulation to the measured airstream and calculated based wind resistance.through adjusting the estimated wind resistance of branch tunnels.It makes the amount of wind of the ventilation network simulation to be according with the actual results of the mine tunnels.So it can realize the reliability testing of the ventilation network of the whole mine.This method was applied in a coal mine.It was found that this way would obtain scientific and precise branch resistance of the whole mine that is the technological basis of the ventilation reconstruction of the mine.
