Abstract
An intelligent detection and recognition system and method for a coal-rock interface of a mine are provided. The intelligent detection and recognition system mainly includes an intelligent lifting support fastened to the top of a shearer, a non-contact radar antenna disposed at the top of the intelligent lifting support, and an operating terminal with which the radar antenna wirelessly conducts information transmission. In an operating state, a radiation direction of the radar antenna is perpendicular to the surface of a to-be-detected coal seam, and the operating terminal is configured to acquire radar data of the to-be-detected coal seam collected by the radar antenna, and draw and display a coal-rock horizon occurrence curve according to the radar data.
