摘要
根据凡口铅锌矿深部矿床岩体物理力学性质及地应力场特性,为岩爆的预防和控制设计了不同的卸压措施,并应用三维弹塑性有限元程序对各种卸压措施引起的应力分布规律进行了数值模拟分析,以期为凡口铅锌矿深部矿床开采和地压控制提供决策依据。
Based on the physical and mechanical properties of deep deposit and characteristics of the crustal stress field in Fankou lead-Zinc Mine, several different stress-relief measures were proposed to prevent and control rock burst. Meanwhile the stress distribution rule under different stress-relief measures have been analyzed by means of numerical simulation based on 3-D elastic-plastic finite element program. The numerical simulation result can be taken as decision-making reference for deep deposit exploitation and geopressure control in Fankou lead-Zinc Mine.
