Abstract: The models about maximum flow and stable flow L8 limestone aquifer in east part of Jiaozhuo Mine Area are established by quantifying the quality variables according to quantitative theory Ⅰ.In these models,the influential factors on mine flow,such as,geological structure,karst,inrush index,roof weight are selected as basic variables.The error of the two models about mine flow prediction are between 72.5% and 100% according to the tests.The complex correlation coefficient is over 0.7.The results of engineering use are good.The theory and practice show that the models are reliable in practical application.
