Development of Automatic Drawing Software for Coal Mine Three-dimendional Ventilation Stereogram

Based on mine ventilation double-line diagram, the technology of interactive collection of the roadway position parameters and fast modeling method for 3D tunnel model are put forward. The principle of three-dimensional ventilation stereogram automatic drawing and the process of using secondary development of AutoCAD based on C# to realize the function of this module are analyzed. On this basis, the development implementation and practical application are done.
