The invention relates to the technical field of coal mining, in particular to a coal mine directional drilling and reaming device which comprises a crawler, a supporting seat is fixedly mounted on the upper surface of the crawler, an electric guide rail is arranged on the upper surface of the supporting seat, and a positioning frame is fixedly mounted on the upper surface of the moving end of the electric guide rail. And a rotating column is rotationally mounted in the positioning frame. When the broaching toothed plate rotates around the rotating shaft, the moving plate moves in the direction away from the drill rod, so that the pressing roller moves to the outer side of the broaching toothed plate, after the broaching toothed plate broaches a drilled hole in the front, the pressing roller compacts the inner wall of the expanded drilled hole, and when the broaching toothed plate rotates, the pressing roller can synchronously move along with the broaching toothed plate, so that the inner wall of the drilled h
