The geological transparency of intelligent mining face is the premise and guarantee for realizing intelligent and accurate mining of coal resources.The principle and application of borehole radar detecting coal seam roof and floor interface were mainly analyzed.The borehole radar technology was applied to detect the fluctuation of coal seam roof and floor in A Coal Mine in Shanxi Province.The results showed that the predicted coal seam roof and floor interface was in good agreement with the actual coal seam roof and floor interface,having important guiding significance for working face mining.
