Abstract: In order to grasp current research status of automatic drawing technique of mine ventilation network graph for further study, the paper analyzed from three aspects of information collection of network architecture, generation of network path and drawing of network graph in details. It expounded research contents, research results and existing problems of the three aspects, and finally pointed out the future research directions: the introduction of artificial intelligence, research more efficient network path generation algorithms and how to make network graph simpler and more beautiful.
