不同层位巷道相对位置与围岩应力特征相关性研究

Research on Correlation of Different Horizon Roadway Relative Position and Surrounding Rock Stress

在某矿2号、3号煤回风巷道水平距离不变、高差不同的情况下,应用数值模拟的方法,模拟研究了2号煤回风巷对3号煤回风巷右帮的影响,并对比分析了其垂直应力分布情况,得出了两巷道不同层位关系的应力特征。

Under conditions of same horizontal distance of No.2 and No.3 return air roadway and different discrepancy in el-evation, the author researched influence of No.2 coal return air roadway to right side of No.3 coal return air roadway, and analyzed distributed situation of perpendicular stress by using methods of numerical simulation. Finally, the author obtained stress features of different horizon relationship of two roadways.
