| 摘 要： | 结合高家梁煤矿斜井泥岩的流变变形特征, 对泥岩进行分析建模, 设计有效的泥岩斜井支护措施. 通过对泥岩进行蠕变加卸载试验, 采用统一流变力学模型理论建立了能表现泥岩流变特性的弹性--黏性--黏弹性--黏弹塑性模型, 并确定了流变模型参数. 结合泥岩试验测得的泥岩力学特性和现场观测资料, 设计采用锚喷网联合支护方法, 并采用大型有限元软件ADINA进行数值模拟分析, 该支护方法能有效控制泥岩变形, 采用的锚喷网支护方法合理可靠.

| Abstract: | According to the rheological deformation characteristics of mudstone around an inclined well in Gao Jia Liang mine,this paper proposes a mudstone model with effective support measures for the inclined well. Through mudstone creep loading and unloading tests and based on the model theory of unified rheology,an elastic-viscous-visco elastic-visco elastic-plastic model is established,which can reasonably represent rheological properties of mudstone,and the model parameters are calculated.Through analyzing muds... |
