介绍一种与锚杆联合使用的锚杆联系链及其组合支护方式，重点研究其围岩锚固机理，采用数值模拟和现场试验的方法对锚杆联系链组合支护效果进行分析。结果表明，锚杆联系链、锚杆和混凝土喷层三者之间的有机结合提高了围岩的自支撑能力；锚杆联系链组合支护具有作业时间短、安装方便、结构简单、成本低等优点；在兼具喷锚网支护优点的同时，锚杆联系链组合支护也弥补了喷锚网支护的不足，是对矿山现行支护方式的补充和改进。

This paper introduces bolt connecting chain which is used together with bolts and its com-bined supporting method ,with the discussion focused on its rock anchoring mechanism .It analyzes the effect of combined anchor supporting of the bolt connecting chain .The results show that the com-bined use of the bolt connecting chain ,anchors and sprayed concrete layer can improve the self-sup-porting ability of rock .The bolt connecting chain has many advantages ,such as shorter operation time ,easy installation ,simple structure and low cost .While boasting the advantages of shotcrete rock bolt wire mesh supporting ,it makes up for the disadvantages of the wire mesh supporting ,pro-ving to be a supplement for and improvement on the existing supporting methods in mines .
