| 摘 要： | 离散单元方法特别适合于节理比较发育的岩体。对于模拟和分析矿山中因采矿引起的围岩松动和冒落等力学行为是比较有效的。用离散单元法研究了大冶铁矿狮子山采区露天转地下开采，采用充填法、崩落法采掘对露天边坡和围岩的影响及围岩变形规律，并得出了相应的结论，为设计和方案的选用提供了一些有益的根据。 |

| Abstract: | Discrete element method is a powerful numerical analysis means to model jointed rockmass, and is very suitable and efficiency to model mechanical behaviors of surrounding rockmass, such as loosening and breaking caused by excavation when mining. The stability analysis of slopes and surrounding rocks during the Daye iron open-pit-mine transferring to underground mining by using discrete element method is carried out. Some cases by using different mining schemes are studied as well. Instructive results and suggestions are obtained. |
| Keywords: | discrete element method numerical modeling open-pit-mining underground mining |
