Abstract：Solid-liquid coupling simulation is developed on the basis of experimental study on solid model material. The problem is solved in this paper that solid model material will collapse when it meets water. At the same time，the problem of the coupling of similarity ratio and the visiblity of different materials is also solved. The mining in shallow coal seams underlying in desert with rich water is simulated by tests and it is proved that the developed materials are suitable for these simulation tests. Different rock bases can be simulated by the model materials with different ratio of materials and different pressure. Solid-liquid coupling occurring in Daliuta coal mine is simulated with the presented material and testing method，and satisfactory result is obtained.
