| Abstract: | The non linear seepage flow movement in underground coal gasification(UCG) was researched. In the model experiment, by analyzing the distribution and variation of seepage flow field in gasification stove, the mathematics model for 3 D non linear unstable seepage was established. The method of determining the main parameters of the model was explained. Solutions of the model were found with the finite element method. And the calculated values are basically in accordance with the measured ones, indicating that the model is reliable. |
