The invention relates to a route model building method and an underground communication method, in particular to an underworkings route model building method and an underground communication method based on the underworkings route model building method. The problem how underground staff or a mobile device finds paths from a departure place to a destination in underworkings when danger occurs underground is solved. The underworkings route model building method includes the steps that an underworkings model is built according to the space topological structure of the underworkings, a base station model is built according to base station coordinates, and a base station and turning point information table, an adjacent base station data structure table and a base station path data table are set up according to base station position information in the underworkings; whether data exist in the underworkings model, the base station and turning point information table, the adjacent base station data structure table and the base station path data table or not is judged, if yes, a base station set is obtained, and underworkings inflection points are added to communicating paths between any two communicated base station nodes; all the paths from the departure place to the destination are obtained. The underworkings route model building method is used by the underground staff or the mobile device for finding the paths in the underworkings when the danger occurs in an underground coal mine.
