| 摘 要： | 本文采用ＦＬＡＣ非线性大变形程序对小铁山矿沿脉联络巷道无支护时和锚杆支护时的受力和变形特征进行了分析，结果表明锚杆支护结构可以很好地限制巷道的变形。通过计算，为合理地进行巷道支护设计和锚杆支护结构参数的选取提供了依据。

| Abstract: | This paper used FLAC nonlinear and prominent deformation program to analyze the load and deformation characteristic of connection drifts with and without rock-bolt support in Xiaotieshan Mine and the result showed that rock-bolt support structure could limited the deformation of drift quite well,thus provided by computation the basis for properly selecting the parameters of rock-bolt support structure and performing the support design of drift. |
