固-液耦合试验材料的研究

在固体模型材料研究的基础上，研制了“固-液”两相模型材料，从而解决了固体模型材料遇水崩解的问题，同时也解决了不同介质材料相似比的耦合以及水沙溃流的试验可视性问题。对富水风积沙层下采煤进行了模拟试验研究，证明所研制的相似材料是可行的。而且通过不同配合比和不同成型压力，可得到变化幅度较大的模型材料，此方法可用于更广泛地模拟不同的岩石基础。

EXPERIMENTAL STUDY ON SIMULATION MATERIALS FOR SOLID-LIQUID COUPLING

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..
