摘要
介绍了万利一矿31304切眼大断面锚网支护项目采用锚网动态信息设计方法,确定锚网支护参数,并应用FLAC3D软件对锚网支护进行了稳定性分析;通过现场观测评价支护效果,反馈信息优化设计,实现了初步设计与工程相结合的动态设计。较好地解决了万利一矿大跨度切眼锚网支护的技术难题,可供相似巷道的支护设计参考。
The paper introduced the dynamic information design methods of anchor net support for large section open-off cut in Wanli Colliery, determined the anchor net support parameters and analyzed the stability of anchor net support by FLAC3D. Through field ob- servations, supporting effect evaluation and optimization design by information feedback, dynamic design method that combined prelimi- nary design and engineering was achieved. The method solved the technical problems of large span cut with anchor net support and can be used for similar roadway design.
