矿岩可崩性是判别矿山能否采用自然崩落法采矿的重要参数，通过对Monte-Carlo模拟技术原理的分析，研究节理面空间块度分布的特征，经合理选取优势节理组，对影响可崩性评价的参数进行定量分析，建立矿岩块度三维模型，利用Makeblock软件系统对矿岩进行可崩性评价。利用上述方法对金川Ⅲ矿区进行可崩性评价，评价结果表明崩落块度体积在0.1～1.4 m3之间，其中体积小于0.4 m3的块体占85.5％，矿体采用自然崩落法进行开采的效果很好。同时，为证明Monte-Carlo模拟法的可靠性，采用劳布施尔法对金川Ⅲ矿区的矿岩可崩性进行分析，结果表明，运用Monte-Carlo模拟法对矿岩可崩性评价是可靠的。

Cavability of ore -rock is the important parameters which can judge the mine by using block caving method.Through analyzing Monte -Carlo simulation technology theory , the characteristics of the joint surface's dis-tributional space was researched , and the reasonable advantage of joints were selected , the related parameters which is thought important too were analyzed , and the 3d model block was built , finally, Makeblock software sys-tem was used to evaluate .This method is applied to ore -rock fragmentation evaluation on No .3 mining area in Jin-chuan.The simulation results show that block caving volume is between 0.1 and 1.4 m3 and the blocks volume less than 0.4 m3 is 85.5%.It is believed that it is an effective method to evaluate the cavability of ore -rock .At the same time , Laubscher's caving chart can be used to prove the reliability of the Monte-Carlo simulation method .The results show that using Monte-Carlo simulation method is reliable .
