深部软岩巷道支护探究
|
摘要
结合具体工程实际,在分析矿井巷道变形破坏特征的基础上,借助数值模拟手段对巷道位移变形特点进行总结分析,从而提出了具有针对性的"初次支护+锚注加固"联合支护方案,为矿井生产作业的更加安全、高效提供了保障。
Combined with specific engineering practice, on the basis of analyzing the characteristic of the mine roadway deformation damage, with the help of numerical simulation method, this paper summarized and analyzed the characteristics of roadway displacement and deformation and put forward the targeted "primary support + anchor injection reinforcement" combined supporting scheme, which provides a guarantee for the safety and efficiency of mine production.
