摘要
基于高应力巷道围岩破坏机理和变形特点,提出了锚网喷索注联合支护技术,并结合具体工程实践进行了验证,取得较好效果。
On the basis of the failure mechanism and deformation features of surrounding rocks in high stress tunnels,the paper presents a combined supporting technology with anchor net spray,belt,and grouting.The engineering practice proves its ideal effect.
