| 摘 要： | 岩爆的预防和控制对深部高应力区矿床的安全开采具有十分重要的意义。根据凡口铅锌矿深部矿岩体的物理力学性质及地应力场特性，对凡口矿深部矿床开采的岩爆防治措施进行了研究，并应用三维弹塑性有限元程序对各种防治措施引起的应力分布进行了数值模拟分析，以期为凡口铅锌矿深部矿床开采的岩爆控制提供决策依据。

| Abstract: | The prevention and control of rock burst are of great significance for safely exploiting deep deposit in high-stress area. Based on the analyses of the physical and mechanical properties of ore/rock and the behavior of ground stress field in the deep deposit of Fankou Lead-zinc Mine,the authors researched the unloading measures to prevent and control rock burst in mining the deep deposit, and carried out numerical simulations of the stress distribution under different unloading mining situations by means of 3-D elastic-plastic finite element program, so as to give decision-making basis for controlling rock burst in exploiting the deep deposit of Fankou Lead-zinc Mine. |
