摘　　要：以眼前山铁矿为例,基于岩性、构造、节理裂隙和岩石RQD作为评价指标,形成了RMR可崩性评价综合模型。结果显示,眼前山铁矿矿区东部RMR值明显高于西部和中部,深部RMR值也较浅部较高,说明中西部和浅部岩石的可崩性更好。Taking Yanqianshan iron ore as an example,the lithology,fault,joint fissures and rock RQD are used as evaluation indicators to form a RMR caveability evaluation model.The RMR distribution of Yanqianshan iron mine shows that the RMR values in the eastern part of the mine are significantly higher than that in the west and the middle,and the deep RMR value is also higher in the shallow part,indicating that the rock in the midwest and the shallow part is much better.

关 键 词：眼前山铁矿 可崩性评价 RQD 节理裂隙 RMR
