The mine ventilation simulation system usually draws and displays a single-line ventilation diagram,which can not reflect the layer relationship of roadways.on the basis of in-depth study of connecting relationship of ventilation roadways,an new and more efficient method to rapidly and automatically draw stereogram of mine ventilation system was put forward creatively.This method delicately offsets the defect of the conventional method and has the features of universality,small amount of calculation and efficient execution.Further more,it provides certain referential value for improving the mine ventilation simulation system and solving similar problems in other fields.
