6) anchoring and grouting
锚注
1.
Then the incompact rock block was consolidated to unity with anchoring and grouting in permanent support,and the cohesive strengths and internal friction angles of the surrounding rock were also improved,which make the surrounding rock mass change from soft to hard and no-supported effect to support structure.
通过对华丰煤矿-1100水平巷道破坏机理的研究,提出了采用马蹄形巷道支护断面和全封闭支护的理念,加强底板承载能力和巷道抗蠕变能力;根据千米深井巷道围岩流变特性,研究得出了围岩地压得到合理释放趋于稳定时进行永久支护的时机和距离,并在永久支护中实施锚注加固,使松散破碎岩块胶结成整体,提高了围岩的内聚力和内摩擦角,使围岩由"软"变"硬",使无支护作用的围岩体变为支护结构,同时锚注锚杆成为全长锚固锚杆,加强了围岩的加固效果,达到安全永久支护巷道的目的。
2.

根据现场膨胀性软岩持续变形的特点,通过改变支护参数、施工工艺、提高支护初撑力等手段,进行了"喷-锚喷-锚网喷"支护技术的工业性试验,对大变形巷道底臌采用了锚注结合的治理方式。
补充资料：弹性滞后
分子式：
CAS号：
性质：一种动态黏弹性现象，即聚合物在交变应力(应力大小呈周期性的变化)作用下，形变的变化总是滞后于应力的变化。产生该现象的主要原因是聚合物受外力后，其链段的运动要克服内摩擦力，从一种状态过渡到与外力相适应的状态需要一定时间，故形变不能立即产生；同样当外力除去后，形变也不能马上回复。弹性滞后使汽车轮胎、橡胶传送带、塑料齿轮等制品产生力学阻尼(内耗)等动态黏弹性现象。
