The simulation material ezperiment research on waterrock interaction in underground mining engineering
Solid-liquid coupling is the interaction between solid (rock) and liquid (water) in the rock engineering. It is the result of the flowing of liquid and the breakage and deformation of rock. The seepage field and stress field exist in many rock engineering, the two fields coupling is simplified in past simulation materials experiment for the materials will collapse when meeting the water, so these experiments are not real coupling simulation materials experiment. With the development of Solid- liquid coupling simulation materials, this paper has solved the problem that model materials collapses when meeting the water, at the same time, it has solved the problem of the coupling of simulation ration and the visibility of experiment process. Through the simulation of coupling seepage field and stress field in underground mining in shallow coal seams underlying in desert with rich water, it proved that the researched materials are suitable for these simulation experiment tests. The modeling materials can be used to simulate different rock bases with different ration of materials and different pressure, so solid-liquid coupling experiment research has been realized with the research of this kind of experiment materials. The success of this experiment has found a new way to research coupling seepage field and stress field, and it also provided the foundation to study Solid-liquid coupling in the further.
