| 摘 要： | 在确定矿岩可崩性的基础上，根据岩体中节理面的空间分布规律，采用Monte Carlo技术模拟节理系统，对矿岩块度影响因素进行定量分析，利用矿岩块度预测三维模型及软件系统Makeblock，对矿岩块度进行有效预测.将上述方法应用到金川Ⅲ矿区矿岩块度预测中，并对该矿区崩落矿石块度进行综合评价.

| Abstract: | Based on the determined cavability of ore-rock and spatial distribution rules of joints,the joint system was simulated by means of Monte Carlo technique and influential factors of ore-rock fragmentation were analysed,ore-rock fragmentation was predicted effectively by using 3D model of fragmentation prediction and software system Makeblock.This method was applied to ore-rock fragmentation prediction of No.3 mining area in Jinchuan and ore fragmentation for block caving was evaluated comprehensively,these results can be used as theoretical basis for design and practice of block caving. |
