摘　　要：通过对玲珑金矿深部岩石的循环加卸载试验、单轴和三轴刚性试验以及三维数值模拟计算,从整体上揭示了玲珑金矿岩石内聚集较高弹性应变能和深部岩体中分布较大弹性能的现象,并且这些弹性能释放具有很高的冲击特性。结合多种理论判断岩爆准则,得出玲珑金矿深部开采具有潜在的强岩爆可能性,并且岩爆总体上讲是可以预测的。同时,根据现场实际施工情况,提出了相应地防止岩爆发生的对策和安全措施。The experiments of cyclic loading and unloading,uniaxial and triaxial stiffness of rock and the numerical modeling analysis of deep rock mass are completed in Linglong gold mine.Based on the results the experiments and numerical modeling,the phenomena of higher elastic strain energy and the distribution of rather large elastic energy resilience in deep rock mass are analyzed in general.The releasing of the elastic energy resilience has high impact characteristic.The great possibility of rock burst during deep mining excavation in Linglong gold mine are concluded by using various prediction criteria of rock burst.The conclusion is that the rock burst can be forecasted.The methods and the safety precautions against rock burst are also proposed according to the actual construction.
