摘要
当前,煤巷锚索支护设计参考锚索的指标与工程指标有较大差别,本文通过计算得出锚索的工程指标,并总结多种途径提高其工程特性,使锚索适应围岩的大变形,提高锚索支护性能。
There are much difference between the practical anchor rope index and engineering index referenced when design, this paper improves the engineering index though calculation, with many ways to improve the engineering index of the anchor rope to adopt the surrounding rock distortion.
