黄泥夹层灰岩顶板回采巷道支护技术研究

Support Technology of Mining Roadway with Yellow Mud Interlayer Sandwich Limestone Roof

为进一步探究黄泥夹层灰岩顶板回采巷道的支护技术优化路径,结合实际案例,通过仿真分析确定了黄泥夹层灰岩顶板回采巷道存在的风险因素,确定采用锚索网联合支护形式对其进行针对性优化,并确定了支护技术的参数与整体支护方案。对支护效果进行现场测试,结果显示,本次支护方案在降低顶底板位移方面发挥了显著效果,证明了该支护技术的可行性。

In order to further explore the optimization path of the support technical of the mining roadway with yellow mud interlayer limestone roof,the risk factors of the mining roadway with yellow mud interlayer limestone roof were determined through simulation analysis based on actual cases,and the combined support form of anchor,cable and net was determined for targeted optimization,and the supporting technical parameters and the overall supporting scheme were determined.The field test of the support effect showed that the support scheme played a significant role in reducing the displacement of the roof and floor,which proved the feasibility of the support technology.
