摘要
以开滦范各庄煤矿3285S工作面上风道为工程背景,通过现场工程实验等手段,采用中空锚索锚注加固技术,对深部巷道两帮进行锚注加固,实现了对巷道围岩的有效控制。
Based on the engineering background of the airway in 3285S working face of Fangezhuang Mine, Kailuan, the hollow anchor cable bolting and grouting reinforcement technology was adopted to reinforce the two sides of deep roadway by bolting and grouting, and the effective control of the surrounding rock of roadway was realized.
