Taking water-inrush phenomena caused by the fault activation as the starting point, this article puts forward the concept of water-inrush phenomena caused by the fault activation. And then, based on the catastrophe theory, a mathematical model of this nonlinear dynamic phenomenon is set up. Through analyzing the geological factors, fault parameters and mining factors, combined with the fault activation water-inrush sample database caused by the fault activation, the evaluation index system of water-inrush risk induced by the fault activation is constructed, which could be used to predict the risk of water-inrush caused by the fault activation during mining under different conditions. In the end, through the analysis of the trend of water-inrush risk caused by the fault activition under the comprehensive function, the article further optimizes the mining parameters, thus to reduce the probability of water- inrush caused by fault activation.
