摘要
针对复杂地质条件下巷道支护困难、常规支护方法失效的情况 ,设计了与摩擦锚杆联合使用的锚杆联系链。经现场试验和理论分析表明 ,锚杆联系链的支护效果很好 ,是一种经济。
Countering difficult tunnel support and conventional supporting mechod which is out of effectiveness under complex geological conditions ,the bolt connecting chain which is used jointly with friction bolt is designed.It shows from in situ experiment and theoretical analysis that the bolt connecting chain is an effective,economical and practical supporting unit.
