现以中空注浆锚索技术在某铁矿软岩巷道支护中的应用为例,对中空注浆锚索技术进行论述。依据试验结果分析发现将中空注浆锚索技术应用在软岩回采巷道中,可以简化注浆施工步骤,实现锚索与锚杆同步承载,从而形成整体支护,增强了支护效果,实现了锚注结合,为其他软岩巷道支护提供了实践经验。
The application of hollow grouting and anchor cable technology in soft rock roadway support of an iron mine is taken as an example to discuss hollow grouting and anchor cable technology. Based on the test results, it is found that the hollow grouting and anchor cable technology can be used in the soft rock mining roadway to simplify the grouting construction steps and realize the simultaneous bearing of the anchor cable and the anchor rod, thus forming the integral support and enhancing the support effect. Combined with anchor and injection, it provides practical experience for other soft rock roadway support.
