摘要
采用数值模拟方法对煤巷锚杆支护进行分析研究 ,获得煤巷锚杆支护围岩应力分布规律及矿压显现规律 ,验证了支护的合理性 ,为优化煤巷锚杆支护参数 ,控制围岩变形提供了理论依据。
Numerical simulation analysis is adopted in the paper to study gateway bolt supporting. The reasonableness of support has also been verified in the study, and the laws of surrounding rock stress distribution and of strata behavior of stress in coal roadway supported by bolt are obtained. These provide the theoretical basics for optimizing bolt support parameters, controlling deformation of surrounding rock.
