Uses model method to establish experiment theory and to construct experiment table, the photos about distribution of flow field were recorded by the camera, when using tracer method apply to the conditions of different fluxes and concentration. According to experimental results, the law of fluid migration and the biggest influence scope of fluid migration are concluded. These numerical magnitudes that the biggest influence scope of fluid migration are converted to the numerical magnitudes of the actual engineering on the basis of similitude ratio, which afford the referential advices to improve the efficiency of building groove in the actual engineering.
