| 摘 要： | The paper introduces a kind of full-length recoverable resin-metal bolts, expounds its structural principle and stress features, and gives some instances in laboratory tests and underground tests. The results show that full-length recoverable resin-metal bolts can be used for supporting the walls of class I - lU mining gateways, that the anchoring force is 50 kN or so, and that the recoverability rate is more than 80%, thus the supporting effect is better than that of split-set bolts.
