摘要
软岩巷道作为井下深部回采中十分常见的一种巷道形式,如何实现对其围岩稳定性的有效控制对矿井生产安全开展意义重大。文章以此为着手点,针对软岩巷道失稳及高强全锚注支护开展探究。笔者结合具体工程实际,文中在分析软岩巷道失稳原因的基础上,对巷道围岩支护设计原则作出总结,并基于此提出高强全锚注支护工艺,希望能够为其他矿井相似工程的开展提供借鉴与参考。
As a very common roadway form in deep underground mining,how to control the stability of surrounding rock effectively is of great significance to the safety of mine production.Taking this as the starting point,this paper probes into the instability of soft rock roadway and high strength full anchor and grouting support.In this paper,combined with the concrete engineering practice,on the basis of analyzing the causes of instability of soft rock roadway,the design principles of surrounding rock support of roadway are summarized,and based on this,the high strength full anchor and grouting support technology is put forward,hoping to provide reference and reference for the development of similar projects in other mines.
