在分析了沿空留巷巷旁充填墙体稳定性控制过程中存在问题的基础上,从优化巷旁墙体自身承载能力和改善巷旁墙体外部受力环境2方面入手,提出了充填前材料选择,预置钢筋网架,顶板锚杆锚索加强支护,充填后墙体锚杆加固,以及协调围岩支护体系等巷旁墙体稳定性控制技术,结合沙曲矿24207大采高强扰动工作面留巷工程实践,取得了预期的效果。

Based on the analysis of the existing problems in the process of stability control of gob-side entry retaining wall in gob-side entry retaining, the optimization of the load-carrying capacity of gondola-side wall and the improvement of the external stress environment of gondola-side wall are put forward. Material selection, pre-reinforced steel mesh, roof bolt and anchor cable to strengthen support, wall reinforcement after filling, and coordination of surrounding rock support system and other roadside wall stability control technology, combined with 24207 mining large mining High-strength disturbed face retaining lane engineering practice, and achieved the desired results.
