This paper emphatically deals witn the experimental method of the electric network simulation of realizing the optimum adjusting parameter with the undetermined boundary value problem-the 'grey box'problem, which the amount fo airlow is given by coalmining wind field.

本文重点讨论了采煤风场给定风流量不适定边值问题(“灰盒”问题)实现代化调参的电网络模拟实验方法,实例中获得一组优化的风场流网,指出沿回风巷老采空区一侧实现惰性化的措施.

Grey system is used in this paper to study the overlaying bed movement and the relationship between supports and surrounding rock. The forecasting methods of comprehensive grey parameters (weighting spans and support load) are introduced in the paper, which includes three steps-grey modelssetting, calculating process and practical examples. Studies shod that the grey models can simulate or reflect roof pressure parameters changing and its inner rules.

Based on the theory of Grey system, a GM <1.1) grey model was established by reverse time sequence of displacement measurement and used to predict the displacement of tunnel surrounding rock which took place before measurement.Then, based on the original bata such as the measured tangential stress value on the section of surrounding rock and the sum of measured displacement value and the predicted displacement value before measurement, a linear equation including separately reversely-determined parameters was established with fictitious boundary element method and various parameters were obtained by the solution of the equation. Finally, the weighted average of each reversely-determined value was obtained and imputted into fictitious boundary element program to extract the relative displacement of relevant surveying line,resulting in satisfactory results.

本文根据灰色系统理论,用量测位移的反时间序列建立灰色GM(1,1)模型,以此模型预测巷道围岩在量测前发生的位移,然后以断面上围岩切向应力量测值和围岩收敛值以及量测前已释放的位移预测值之和为原始数据,用虚边界元法建立包含独立反算参数的线性方程组并求解各参数,最后求取加权平均后的综合反算值,并将其输入虚边界元程序,求出相应测线的相对位移,得到了令人满意的结果。
