| 摘 要： | 以某矿地质条件为基础建立数值计算模型,利用三维离散元数值分析软件3DEC,模拟巷道分别在采用原支护方式及新设计的4种优化支护方案的情况下围岩的变形情况,并通过各方案支护效果的相互对比,确定了最佳的支护方案。模拟结果与实际情况相符,可为矿井巷道支护优化设计提供参考。

| Abstract: | In this paper,a numerical calculation model was established on the basis of the geologic conditions of a mine,the surrounding rock deformation of the roadway in the case of respectively adopting the original support pattern and the newly-designed four kinds of optimized support schemes was simulated with 3DEC,and the best support scheme was determined through the comparison of the support effect of different support schemes.The simulated results tallied with the actual situation,so they can be regarded as the reference for the optimization design of the mine roadway support. |
