摘　　要：深部采矿有时会发生岩爆。简述了传统的岩爆预测方法。以实际工程资料为基础,通过理论分析,提出了采矿洞窟周边各向应力均达到或超过洞窟周边岩体极限压碎强度时就会发生岩爆的结论,并根据此结论总结出了可有效预测岩爆的极限应力均衡法,并给出了一种洞窟周边各向应力计算新方法。用此新方法预测岩爆的结果,与实际情况有较好的吻合性。Sometimes the rock burst may occur in underground depth-mining. The conventional methods of predicting rock burst are briefly introduced in this paper. Based on the data of practical engineering and theoretical analysis, the conclusion has been reached that the rock burst occurs once each stress around the mining cave is up to or strong than the limit crush strength of the rock stratum around the mining cave. Base on this conclusion, the limit stress balanced method to predict rock burst and a new method to calculate each stress around the mining cave have been presented. The results of predicting rock burst by use of the new predicting method are in keeping with the practices.
