| 摘 要： | 从理论上分析了沿空巷道顶板的变形机理；运用数值分析方法研究了沿空巷道层状顶板的变形特征及其影响因素；对沿空巷道顶板变形对锚固结构的影响进行了分析，得出了以下主要结论：（1）沿空巷道顶板的变形主要是由于老顶回转引起的；（2）沿空巷道层状顶板的横向变形较为显著；（3）层状顶板的横向错动变形增大了对锚固结构的剪切应力，对锚杆及锚固结构提出了新的要求。

| Abstract: | The mechanism of deformation in goaf road roof is analyzed in this paper theoretically,and the character of deformation in goaf road and its influencine factor are studied based on the numerical analysis,the influence of deformation in goaf road on the rock bolt structure is analyzed finally,and a conclusion is drawn: 1) the deformation of goaf road roof is caused by the turn-over of the old roof primarily;2) the transverse deformation of goaf road roof is evident;3) the transverse deformation of the layered roof increases the shearing stress effect on the rock boft structure,causing a new problem for rock bolt structure. |
