Abstract
Based on fractal theory, the capacity dimension in the fractal dimension is taken as the basic feature quantity. The grid covering method was used to quantitatively evaluate the structural complexity of Donghuantuo Mine. Based on this method, the positive relationship was found between the structural complexity and permeability coefficient with using the fractal theory. And the value of permeability coefficient is optimized for empirical formula to be closer to the real situation. Thus, the prediction accuracy of water inflow is improved.
