摘　　要：三山岛金矿深井开采岩爆问题突出,为了保障作业面安全,提出了卸压孔卸压方案,建立了三维数学模型对卸压效果进行了分析,并通过三山岛金矿深部-780 m采场进行了实施。应力测试结果表明,卸压孔可以有效形成一定范围的降压区,降低了岩爆发生几率。Rockburst is a serious problem in deep mining of Sanshandao Gold Mine.In order to ensure the safety of the working face, this article puts forward a depressure release scheme, establishes a three-dimensional mathematical model to analyze the pressure relief effect, and carries out the implementation through the deep-780 m stope of the mine.The stress test results show that pressure relief holes can effectively form pressure relief area and reduce the probability of rock burst.
