锚注综合加固技术在小煤柱大跨度巷道群的应用

Application about Combrehansive Reinforce Technology of Bolt Grouting in Roadway Groups of Small Coal Pillar and Large over-the-roadway

介绍了小煤柱大跨度巷道群在受到构造和采动双重影响下,应用动态信息设计法,建立大模型模拟不同加固方案与支护参数,从而选择出最佳方案,同时分析了矿压监测结果,显示该加固方案具有较高的合理性和可靠性。

This paper introduces dynamic information method under small coal pillar and large over-the-roadway roadway groups influnenced by full extraction and structure,building large model simulates diffierent reinforcing scheme and supporting parameter,the best scheme is obtained,through analyzing rock pressure,this method is rational and reliable.
