The invention relates to the technical field of grouting filling facilities, and discloses a grouting filling system which comprises a gangue pulping subsystem, a coal ash pulping subsystem, a gasified slag pulping subsystem and a filling subsystem. A feed port of the filling subsystem communicates with the gangue pulping subsystem, the coal ash pulping subsystem and the gasified slag pulping subsystem at the same time. The coal ash pulping subsystem communicates with the gasified slag pulping subsystem. A discharge port of the filling subsystem communicates with an overlying stratum separation layer. According to the grouting filling system, by arranging the gangue pulping subsystem, the coal ash pulping subsystem, the gasified slag pulping subsystem and the filling subsystem at the sametime, gangues, coal ash and gasified slag with different particle sizes are processed, the processing efficiency of the gangue, coal ash and gasified slag is greatly improved, the harmless disposal ofcoal power solid waste is realized, and the gangue, coal ash and gasified slag can serve as the materials for relieving ground surface subsidence and especially realizing grouting and filling subsidence reducing of the overlying stratum separation layer in a mine.
Description
technical field [0001] The invention relates to the technical field of grouting filling facilities, in particular to a grouting filling system. Background technique [0002] Coal gangue contains a large amount of organic components, and is rich in metals, alkaline earth metals, and sulfides. It is a source of inorganic salt pollution, which can pollute the environment through atmospheric precipitation. Coal gangue is transported from the ground to the surface for disposal, and the drastic changes in the environment strengthen the weathering effect, promote the dissolution of soluble components, and aggravate the environmental pollution of the gangue dump. [0003] Moreover, with the increasing pressure on the treatment of coal gangue from some coal mines, fly ash from thermal power plants, and gasification slag from chemical plants, as well as the increasing pressure on national environmental protection, it is urgent to realize the harmless treatment of solid waste. The tra...
