The invention discloses a three-dimensional simulation test method for directional drilling grouting, and relates to the technical field of mine water disaster grouting treatment. An adopted test system comprises a test bed, a grouting device, a confined water sump device and a data monitoring device, the grouting device provides grouting conditions needed by an experiment for the test bed, the confined water sump device provides dynamic water conditions needed by the experiment for the test bed, and the data monitoring device achieves the dynamic monitoring and information processing functions of the experiment process. The grouting branch pipes are preset in the laying process of the sample, after the grouting branch pipes are laid, the overall shape formed by the positions of all the grouting openings is pinniform or fan-shaped, and test simulation of directional drilling three-dimensional grouting can be achieved. According to the test method, the diffusion and retention mechanism of the grout in water gu
