And, it establishes the computer model with the Scott·Henseleit method, which analyses and optimizes the ventilation network and auto-creates the figures of the evading disaster and succoring disaster with the computer. The paper establishes the GM(1,1) gray forecast model, and forecasts the amount of gasemission of the laneway based on the history data, and then compartmentalizes the danger grade for the laneway. Utilizing the principle and method of cybernetics, the paper brings the feed-forward and feedback. controlling method on the hidden risk in the mine, namely, the double-loop model of forecasting and early- warning. Especially in the feed-forward forecasting, the paper adopts the one unit non-linear regression analysis and forecast method, and forecasts the hidden risk amount in the mine during some time, and compartmentalizes the hidden risk grade based on the history data.
