US 2021/0324737 A1 · INTELLIGENT DETECTION AND RECOGNITION SYSTEM AND METHOD FOR COAL-ROCK INTERFACE OF MINE

Abstract

The present invention discloses an intelligent detection and recognition system and method for a coal-rock interface of a mine. 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. The present invention can not only improve the detection accuracy, but also adapt to a working environment that suddenly changes on a fully mechanized mining face.
