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.

论文中，利用斯考特·亨斯雷法建立计算机模型，对矿井通风系统进行解算和优化调节，并通过计算机自动生成避灾、救灾路线图；建立灰色GM(1，1)预测模型，对巷道瓦斯涌出量进行预测，进而对巷道中的瓦斯事故危险性进行危险等级划分；利用控制论的原理和方法，提出了煤矿通防隐患前馈——反馈控制方法，即预测、预警双环模型，采用一元非线性回归分析预测方法，对煤矿某一段时间内的隐患数量进行预测，并结合历史数据，对当前煤矿隐患排查处理状况划分等级，分别予以管理和控制。

By modeling six kinds of linear and non-linear optimal forecast combining models,this paper com- pares the performance of the linear and non-linear forecast combining methods,as well as neural network methods and other optimal combination methods.
