In China’s northern coal mine area, coal mining face water inrush problem seriously haunted the normal operation of the economic benefits of coal mines. According to the characteristics of coal floor water inrush from coal mining face, a stochastic - information method is proposed to solve the problem of water inrush forecast. The information criterion is set up and a large number of examples are verified. The satisfactory results are obtained.
