摘　　要：根据相似原理，模拟铜矿峪矿５号矿体，对矿块崩落法的矿体崩落规律进行模拟实验，实验结果在定性上揭示了原型矿体崩落的规律：５号矿体可崩性好，采用崩落法是合理的；矿体平均崩落速度为０．２２ｍ／ｄ，放矿可以控制矿体崩落。The analogy principle is used to simulate the orebody No,5 in TongkaungyuCopper Ming.The simulation experiment has been carried out for the orebody caving pat。tern of block caving method.The experiment results havb qualitatively revealed the originalorebody caving pattern,that is,the orebody No.5 suits caving,using block caving methodis rational,the average orebody caving velocity is 0.22 m/d,andorebody caving can becontrolled by ore drowing adjusfment.
