摘要:

以陕北某矿2302为背景,使用FLAC数值模拟软件和“自稳隐形拱”理论对其掘进断面和支护方案进行了优化,从而使之能够更有利于巷道的变形。设计了现场监测方案,并对部分监测结果进行了分析。结果表明:优化的巷道断面和支护方案合理可行,满足了该巷道的安全。

Abstract:

Based on 2302 trough tunnel of some mine in Shan-Bei mining area, optimized it’s section figure and supporting programme by FLAC numerical simulation software and the theory of“Self-stabilized Hidden Arch”, so that it can be in favor of the deformation of 2302 trough tunnel. Designed the monitoring programme and analyzed some supporting datas.The results show that the optimization section figure of 2302 trough tunnel and it’s supporting programme are reasonable and feasible, and met it’s safety.
