| 摘 要： | 结合广东某铁矿矿柱破坏的实际情况,在现场调查的基础之上,采用有限元数值方法对矿柱破坏原因进行了分析。分析表明,矿柱自身地质条件较差(节理裂隙过多)、采场结构参数不合理等是导致矿柱破坏的重要因素。设计了喷射混凝土+锚杆的加固方案。加固方案在矿山实施后,解决了采场出矿难的问题,取得了较好的应用效果。 |

| Abstract: | Combining with the actual damage situation of pillars in aniron mine of Guangdong province,and basing on the field investigation,this paper analyzes the reasons by using the finite element method.The analysis shows that,the main factors causing the failure of pillars are the bad geological condition which has too much joint fissures,and reasonable stope structure parameters.The reinforcement solution of gunite concrete and rock bolt is designed,and after implementation in the mine,the problem of ore drawing is solved,with great application result. |
| Keywords: | Pillar Destruction reasons Finite element Reinforcement solution |
