The invention discloses a material transportation device for a mine. The material transportation device comprises a first bracket and a second bracket, wherein a hydraulic device is arranged on the first bracket; one end of the hydraulic device is hinged to the first bracket, and the other end of the hydraulic device is a hydraulic output end; a material chute is hinged to the hydraulic output end; the lower surface of the upper part of the material chute is hinged to the hydraulic output end; the lower surface of the lower part of the material chute is hinged to the second bracket; the outer surface of the material chute is coated with an erosion resistant coating; the inner surface of the material chute is coated with a slipping enhancing abrasion resistant layer; and the material chute can rotate centering on the second bracket through the telescopic motion of the hydraulic device. A reasonable structure is arranged, so that the functions of the material transportation device is diversified, the adaptability of the material transportation device is improved, the environmental problems that the noise is loud and the dust is serious are relieved, and the durability of the material transportation device is improved. The invention further provides an anticorrosive coating for the material transportation device, so that the corrosion resistance of the material transportation device is improved, and the service life is prolonged.
