| 摘 要： | 采用改进型空心包体应变计,对平顶山八矿进行了地应力的实际测量,并得到矿区地应力测试结果和分布规律;得出了计算区域初始地应力场相应的应力回归公式,并且分析了矿井地应力的分布特征.在此基础上,用有限元法经过对比分析,对平顶山八矿"二水平戊二回风上山"通风巷道进行了优化分析和耦合设计,并对优化前后巷道进行有限元数值模拟.结果表明,在已知地应力基础上对巷道的优化设计可以到达令人满意的效果,做到有的放矢. |

| Abstract: | The paper introduces the in-situ stress measurement using overcoring technique in the eighth mine of Pingdingshan coal mining cooperation,and regularity of in-situ stress distribution is obtained.Based on the determined in-situ stresses,their distribution characteristics are obtained by using theoretical and statistical analyses.On this basis,using the finite element method,optimized coupling analysis and design of tunnel ventilation are carried out.Before and after optimization,finite element numerical sim... |
