摘　　要：岩爆是在高地应力区地下洞室开挖卸荷过程中发生的,岩爆特征与岩石卸荷破坏特征密切相关。在回顾用卸荷岩石力学研究岩爆历史的基础上分别从试验研究、理论研究方面提出了当前卸荷状态下岩爆研究中存在的问题,并对今后的发展提出了一些看法。Rockburst is met under the unloading conditions during the excavation of underground cavity in high geostrese areas, whose characteristic relate closely with the characteristic of rock breakage in unloading conditions. On the base of reviewing current status of unloading rock mass mechanics for rockburst, the main problem are presented from experimental research and theoretical investigation. Some opinions are brought forward.
