| 摘 要： | 利用数值模拟软件建立了某磁铁矿岩体在不同地应力条件下的巷道支护方式模型, 分析了其巷道变形及应力分布变化情况, 指导矿山井下巷道支护。同时为了更好满足支护要求, 引入了锚喷加锚杆联系链的支护方式, 数值模拟结果与现场实测数据对比表明, 锚喷加锚杆联系链的支护方式对巷道的稳定性更为有利。

| Abstract: | Roadway supporting model was established with a numerical simulation software for magnetite orebody underground in different stress condition, which can be used to analyze the roadway deformation as well as change in the stress distribution so as to be guidance in the roadway supporting underground. After a combination supporting method with anchoring and shotcreting support plus bolt connection chain support was introduced, the comparison between numerical simulation result and practical measurement showed that such new combination supporting method is more favorable to the stability of roadway. |

| Keywords: | magnetite numerical simulation roadway support bolt connection chain deformation monitoring |
