ABSTRACT
On the basis of 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. Using this method, a positive relationship was found between the structural complexity and the permeability coefficient using the fractal theory. The value of permeability coefficient is optimized to match the empirical formula to the real situation. Thus, the prediction accuracy of water inflow is improved.
