应变能是诱发矿山岩爆的关键因素。岩爆的发生不仅取决于岩石的应变能储存特性，而且还取决于采动过程中应变能积聚的环境。本文通过实验研究了玲珑金矿采场周围岩石中应变能的分布特征，并采用三维数值模拟方法进行了研究。与已有的岩爆判据进行了对比，对-570 m采深的岩爆进行了综合预测。研究表明，应变能分析结合数值模拟在岩爆预测中是有用的。(C)2001爱思唯尔科技有限公司版权所有。
Strain energy is a key factor of inducing rockburst in mine. The occurrence of rockburst depends not only on the property of storing strain energy in rocks, but also on the environment of strain energy accumulation in mining. This investigation has been carried out on the property of strain energy stored in rocks by experiment and of which distributed around the mining pits of Linglong gold mine in China by using three-dimensional numerical modeling. In comparison with the pre-existing criteria of rockburst in literature, a comprehensive prediction of rockburst has been made so far as the ores are extracted at the depth of -570 m. The study shows that strain energy analysis with the aid of numerical modeling is useful in prediction of rockburst. (C) 2001 Elsevier Science Ltd. All rights reserved.
