Abstract: A coal gangue-based ecological restoration material, and a preparation method and an application thereof are provided. The coal gangue-based ecological restoration material is made from the following raw materials in parts by weight: 10 parts by weight of coal gangue; 0.5-1 parts by weight of an adhesive; 1-10 parts by weight of a plant fiber; and 1 part by weight of a fertilizer. The preparation method of the coal gangue-based ecological restoration material includes: primary crushing, primary heat treatment, primary cooling, secondary crushing, mixing and molding, secondary heat treatment, secondary cooling, mixing, and cooling and molding. The method uses the coal gangue as a main raw material to prepare the ecological restoration material, which can realize the effective utilization of the coal gangue and has good environmental protection, economic and social benefits.
