The deformation and stability mechanisms of pelitic soft rock drift under rich water condition are more complicated than those of the general ones.

摘要富水条件下泥质软岩巷道破坏及稳定性机制比一般软岩巷道更复杂，不仅需要采用多种复合支护控制围岩非线性大变形，还必须进一步控制其泥化进程。

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。

In the simulation model, the cellular automata model was applied to describe the tunnel network system, a methane gas cell was used to represent an energy unit of methane gas which was eradiated from walls of working spaces, mined coal piles, surrounding rocks and excavations, a grid cell was used to represent a tunnel grid and its states, these grid cells contain such state parameters as velocity and quantity of methane gas.

在该方法中，用元胞自动机模型描述地下矿巷道网络系统，用瓦斯元胞来描述从工作面煤壁、采落的煤堆、围岩和采空区渗出的瓦斯能量单元；用格子元胞描述巷道格子及其状态，这些格子元胞均用瓦斯运移速度和瓦斯含量等状态参数来描述。
