摘要
通过强力锚杆、锚索支护技术在破碎围岩巷道中的应用,总结破碎围岩巷道破坏的主要原因及防治原则,针对此类型巷道的特点提出了破碎围岩巷道支护设计的思路,通过现场实践和理论分析,得出该支护设计可以有效控制围岩变形,确保巷道支护效果,为锚杆、锚索支护技术在煤矿破碎围岩巷道中的推广提供了实践依据。
Through the application of strong bolts,anchor support technology in broken rock roadway,we summarized the main damage factors and its prevention principles.Aimed at the characteristics for this type of roadway,we designed the ideas of broken surrounding rock suppport.After on-site practice and theory analysis,we ensured that this design can control the deformation of surronding rock effectively and ensure the roadway effects,which provide practical basis for the bolt and anchor support technology in the coal mine tunnel.
