Grouting method for goaf filled with water

The invention relates to the technical field of goaf treatment, and provides a grouting method for a full-water goaf, which comprises the following steps: arranging material injection holes in a treatment area above the full-water goaf, and filling aggregate to the full-water goaf through the material injection holes; and the slurry is sequentially injected into the full-water goaf from the injection hole in the middle to the injection holes in the outer side. According to the grouting method for the full-water goaf provided by the embodiment of the invention, the aggregate is filled into the full-water goaf through the plurality of material injection holes, and then the slurry is sequentially injected into the full-water goaf from the material injection hole in the middle to the material injection holes in the outer side, so that filling of the goaf is realized, and the dangerous problem caused by surface collapse is avoided. 本发明涉及采空区治理技术领域，提供一种满水采空区注浆方法，该注浆方法包括：在满水采空区上方的治理区域布置注料孔，通过注料孔将骨料充填至满水采空区；将浆料由中部的注料孔
