耦合让均压技术在破碎顶板顺槽中的应用

摘要

以陶二矿18505工作面顺槽为研究对象，运用理论分析、数值模拟及动态现场矿压观测等方法，研究了耦合让均压支护方式在破碎顶板顺槽中的应用情况。通过现场测点的各观测数据，表明巷道支护效果可行且优于原支护系统。耦合让均压支护技术在该实验段能很好控制围岩变形且能降低支护成本。%Taking the crossheading at 18505 working face of Tao'er Colliery as the project research object ,the pa‐per discusses the application of coupling -with-yield support in broken roof crossheading by means of theoreti‐cal analysis ,numerical simulation and dynamic field mineral pressure observation ,w hich is proved superior to the original support system with good control of surrounding rock deformation and low support cost .
