| 摘 要： | 采用相似材料模拟和计算机数值模拟，对沿空留巷老顶破断位置与形状、不同支护方式对顶板活动的影响以及相关的巷旁上技术和进行了初步分析。模拟结果表明，采用锚杆（索）网联合支护和人工筑构较充强度的巷旁充填体，有利于综合机构放顶煤开采沿空留巷顶板的稳定，并给对充填带宽度和充填材料抗压强度的最低要求。

| Abstract: | Through similar material simulation and computer numerical simulation, the breakage situation and the shape of main roof, the influence of different supports on roof activity and the relevant technique parameters for roadside packing were analyzed preliminarily. The results show that bolting with wire mesh and man made roadside packing body with high strength are beneficial to the stability of gob side entry, and the minimum width of packing zone and the minimum compressive strength of packing material were also provided. |
