摘　　要：岩爆是高地应力、脆性岩体中较常见的一种地质灾害 ,它的形成受岩性、地应力、施工因素等各种因素的控制 ,而这些因素又与地壳中的主要断裂带的分布有关 ,通过模拟的岩爆试验 ,探讨了评价岩爆的一些参数 ,提出了岩爆优势面的概念 ,并说明了其在岩爆预测中的应用及对岩爆的处理措施。Rockburst is a kind of familiar geological disaster which takes place in the rock body of high geostress and brittleness. The form of rockburst is charged by factors of lithology , geostress ,construction and so on, but these factors are related to the distributing of main fault strips in the earth's crust .By means of the simulative test of rockburst , the paper discussed some parameters when appraising rockburst, bring forward the concept of rockburst's predominant face and explained it's appliance in rockburst forecast and give the measures in rockburst's treatment.
