The invention relates to the field of tunneling, and discloses a water disaster risk prompting method based on a coal mine tunnel interface, which comprises the following steps: acquiring the conductivity of coal rock at a cutterhead based on an emitting electrode and a receiving electrode on the cutterhead, and acquiring free water information of coal rock distribution and an interface based on an image on a chute or a conveyor belt, determining the interface humidity according to the conductivity of the coal rock and the free water information of the interface, and prompting the water damage risk of the interface based on the change of the interface humidity. According to the method, errors caused by judging the conductivity only depending on direct current and the influence of metal salt contained in the rock stratum on the conductivity are avoided, and water information of a roadway forming interface is further recognized and processed in an image recognition mode. 本发明涉及隧道掘进领域，公开了一种基于煤矿巷道界面的水害风险提示方法，包括：基于
