摘　　要：利用 DDEM(可变形离散单元法)原理和方法,研究了自然崩落法矿体崩落规律。针对具体地质条件和赋存情况及矿岩物理力学性质,采用计算机数值模拟分析了自然崩落法的崩落规律,得出了 DDEM 在用于模拟矿块自然崩落法中崩落规律和分析其崩落机理时是较适合的结论,不仅可以从力学角度对崩落的力学机理进行研究,而且能直观地用图形给出矿体在崩落过程中的具体形态变化,有效地指导放矿,现场试验验证效果良好。Based on the deformable discrete element method (DDEM), the caving law of natural block caving mining method is simulated by numerical method. The results show that the numerical simulation based on DDEM is suitable to analyze the mechanism of natural caving law in block caving method, it not only has function of research on caving mechanism in rock mechanics, but also can easily demonstrate the rock state variation at different times. The comparison with actual state measured in-situ shows that this method has practical accuracy, and can be efficiently used to guide the mining process.
