THE SIMULATION MATERIAL AND EXPERIMENT RESEARCH OF SOLID-LIQUID COUPLING IN UNDERGROUND MINING

摘要

Solid-liquid coupling is the interaction between solid and liquid in the rock engineering. It is the result of the flowing in rock. The problem that model materials collapses when meeting the water has been solved. Through the simulation of coupling seepage field and stress Held 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.
