The invention provides a navigation method and system for rapid routing inspection on mine ground. The method comprises carrying out coordinate and format conversion on mine underground layout graphs (such as a mining engineering plane graph and a mine surface-underground contrast graph) so that requirements of a coordinate system and a base graph format of a navigation system in the mobile terminal are satisfied, and displaying the processed underground layout graphs as navigation interfaces in the navigation system so that the navigation interfaces contain the underground contrast graph. The mobile terminal can automatically acquire the current position coordinates of the mobile terminal in real time when the navigation system is started so that the current position coordinates of the mobile terminal can be displayed in the navigation interfaces of the underground layout. Through the method and system, the underground layout graphs fit to the navigation system in the mobile terminal so that staff positions can be fast found in the navigation map loading the underground layout and the method and system can assist the staff to complete missing ground information on the mining engineering plane graph.
