According to the characteristics of drilling-blasting system and the features of radioactive pollutants in underground uranium mine, the fragmentation model of blasting ore was established by using the adaptive fuzzy inference technology, and the precipitation model of Radon concentration was constructed by using the migration mechanism of radioactive pollutants. The parameters of models were converted to radon concentration model which is related to drilling-blasting parameters, and the integrating model of drilling-blasting system was founded under the control of radon concentration in urani...
