摘　　要：为保障2201工作面回撤区域顶板和回撤通道围岩的稳定,通过分析柔性网护顶技术原理及施工工艺,结合工作面末采区域的具体特征,进行柔性网护顶技术方案中钢丝绳、网片、锚杆索及拖网锚杆等参数的设计,并对回撤通道的施工方式及锚网索支护参数进行设计。根据工作面回撤期间的现场观测结果可知,工作面在现有柔性网护顶和回撤通道支护方案下,回撤期间顶板无大范围漏冒现象,回撤通道围岩处于稳定状态,工作面顺利进行了回撤作业。In order to ensure the stability of the roof and the surrounding rock of the withdrawal channel in the 2201 working face,through the analysis of the technical principle and construction technology of the flexible mesh roof protection,combined with the specific characteristics of the final mining area of the working face,the parameters such as wire rope,mesh,anchor cable and trawl anchor in the flexible mesh roof protection technical scheme are designed,and the construction mode of the withdrawal channel and the anchor mesh cable support parameters are designed.According to the on-site observation results during the withdrawal period of the working face,under the existing flexible mesh roof protection and withdrawal channel support scheme,there is no large-scale leakage phenomenon of the roof during the withdrawal period,the surrounding rock of the withdrawal channel is in a stable state,and the withdrawal operation was carried out smoothly in the working face.
