应力场条件下所产生的岩片飞射抛散,以及洞壁片状剥落等现象叫岩爆。岩体内开挖地下厂房、隧道、矿山巷道、采场等地下工程,引起挖空区围岩应力重新分布和集中,当应力集中到一定程度后就有可能产生岩爆。岩爆是地下施工的一大地质灾害。
Rock fragments generated under the stress field flying scattering, as well as flake wall flaking and other phenomena called rock burst. Excavation of underground powerhouse, tunnel, mine roadway, stope and other underground works in the rock mass will cause the stress of redistribution and concentration of surrounding rock in the hollowed-out area. When the stress concentrates to a certain extent, it is possible to produce rock burst. Rock burst is a major geological disasters underground construction.
