In order to study the effect of karst fracture blocking water, the material selection and ratio of lake mud cement slurry was studied by indoor test and in-site test, the diffusion mechanism of lake mud cement slurry was analyzed, and its performance is evaluated by pressing water test, drilling stone body and filling rate. The results show that the maximum average unit permeability rate of 1.39Lu, is 2.46Lu, meets the design requirements (less than 5Lu); the stone body is full filling, 68.75%, 5.25%, 31.25%, diffusion radius of 5-10m, slurry diffusion filling effect is good; the blocking rate is 95.66% and the grouting rate exceeds 85%.
