摘要（英）：

The invention belongs to the field of goaf grouting visualization simulation. On the basis of a three-dimensional geometrical geological information model, a three-dimensional Bingham fluid mathematical model is established, and the three-dimensional dynamic overall process simulation of storm surge flood routing is realized according to a grouting numerical simulation result. In order to fulfill the aims, the invention adopts the technical scheme that a goaf grouting dynamic overall process simulation method based on numerical simulation comprises the following steps of: (1) establishing a grouting three-dimensional network model which is coupled with the complex stratum information of a goaf; (2) establishing a goaf grouting three-dimensional mathematical model; (3) dynamically simulating the grout flowing of the goaf; (4) performing goaf grouting dynamics calculation; and (5) performing post-processing and visualization output on three-dimensional dynamic overall process simulation. The goaf grouting dynamic overall process simulation method based on the numerical simulation is mainly applicable to the field of goaf grouting in an engineering technology.
