摘要: 采用FLAC3D程序,对矿体实际开采顺序进行了数值模拟,分析上一分段开采所引起的巷道围岩应力、变形以及塑性区域变化情况,得到了围岩应力、变形及塑性区域变化规律,为巷道稳定性控制提供了理论基础。

关键词: 深部开采, 巷道变形, 应力, 影响

Abstract: The numerical simulation on the actual mining sequence of ore-body is made by FLAC3D program to analyze the regional variation of the surrounding rock stress,deformation and plasticity caused by the mining at the upper stage,thus obtaining its regional variation rule.The paper provides a theoretical basis for the roadway stability control.

Key words: Deep exploitation, Tunnel deformation, Stress, Influence
