The invention discloses a power plant flue gas high-adsorbability cementing material prepared by directional dissociation of mine solid waste and a preparation method thereof, and the preparation method comprises the following steps: 1) determining the key component content of each narrow fraction of coal gangue based on a directional dissociation technology, and constructing a corresponding relation model of key components and fraction distribution; and 2) mixing the dry materials of coal gangue, fly ash and cement with water to prepare the cementing material, wherein the dry materials are different in granularity. (3) researching an influence rule of the gangue particle size grading and the filling material ratio on the performance of the cementing material through a laboratory test; 4) obtaining a corresponding optimal ratio according to the components of the flue gas of the coal mine power plant; and (5) selectively crushing the coal gangue by utilizing multi-layer gradient variable-aperture screening equipment, accurately preparing the required mixed-particle-size coal gangue material, and then preparing the material. According to the method, the adsorption performance of the cementing material on the power plant flue gas can be optimized, and cooperative treatment of the power plant flue gas and the mine solid waste underground is facilitated.
