摘要
通过对锚注支护技术的研究,结合顾北煤矿典型软岩巷道变形与破坏形式特征,设计该巷道锚注支护方案,并完成了现场监测。工程实践表明,该技术是一种主动支护技术,具有施工工艺简单、易操作、适应性强等特点,具有较高的推广应用价值。
By researching the bolting- grouting mechanics and technology, combined with the deforming and damage Way feature of the typical soft rock tunnel in Gubei Coal Mine, the bolting - grouting scheme of soft rock tunnel was designed. And the site monitoring analysis and estimating were accomplished. The result of the practical test showed that the technique was an effective way to solve the soft rock tunnel supporting. It has a higher value in application and dissemination.
