利用三维有限元法对铜矿峪铜矿５号矿体和程潮铁矿岩体崩落机理进行研究，探讨了不同削弱工程对采场应力分布的影响，得出了岩体削弱后的崩落机理，同时对初始拉底面积进行分析。
Using three-dimensional finite element method to study the caving mechanism of No.5 orebody and Chengchao iron orebody in Tongkuangyu Copper Mine, and discussing the influence of different weakening project on the stress distribution of stope, the caving mechanism after weakened rock mass is obtained, meanwhile, The initial pull-down area for analysis.
