摘要
以陕北榆阳煤矿2302运输巷道为背景,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。
Based on the No. 2302 transportation roadway of Shaanbei Yuyang Mine as a background, a FLAC numerical simulation software and ＂self- stabilized invisible arch＂ theory were applied to optimize the heading cross section and the support plan and thus the optimized support plan could be favorable to the deformation of the mine roadway. The site monitoring and measuring plan was designed and the analysis was conducted on the partial monitoring and measuring results. The results showed that the optimized roadway cross section and support plan was rational and feasible and could meet the safety of the mine roadway.
