Abstract: Mud flows phenomena in mines are extremely complex，and it is difficult to solve the problem relaying on research of soil liquefactionIn this paper，the numerical simulation of mine rock-body and the soil liquefaction is made with a dynamic non-linear coupled solid and liquid constitutive equation on the platform of OpenSeesAnd the complicated mine mud flows phenomena are analyzed by the non-dimensional analysisThe analysis results are validated with the practice，which directly show the effect of the non-dimensional values on the soil liquefactionThis may provide a fundamental basis for safe mine production
