Abstract: Due to the complex environment of a coal mine and its uncertain conditions of coal and rock, the recognition of coal-rock interface has always been a very difficult problem in the world. From the demand of coal-rock interface recognition in coal mining, this paper expounds the research status of image-based coal-rock interface recognition techniques, analyzes the adaptation conditions of various methods, and discusses the applications of coal-rock interface recognition. Aiming at the existing problems, such as limited experimental condition, and difficulties in practical usage, this paper proposes to combine the image-based 3D modeling method and those methods which focus on the different dielectric property of coal and rock. This method enable us to visualize the vertical direction of the a coal-rock interface, and efficiently control the head movement of a shearer. Finally, simple analysis of the importance and its applications of the camera position is given, which is a help for the research of coal-rock interface recognition.
