| 摘 要： | 用一种新的数据结构和方法重现三维工程岩体模型和块段模型，采用空间数据插值方法对三维地质块段模型中的各评价参数进行有效估值，最后应用可崩性评价方法对矿岩的可崩性进行评价.针对通过不同岩性区域实体模型和块段模型的建立及不同指标的插值，建立了金川Ⅲ矿区矿岩可崩性评价的三维模型.以此模型为基础，应用此种方法对金川Ⅲ矿区矿岩可崩性分级表明，矿岩可崩性属于中等偏上，与生产实际相符.

| Abstract: | 3D engineering rock mass model and block model were reconstructed by a new data structure and method.Each parameter in each block was estimated by geostatistical technique.Finally,cavability of rock and ore was predicted by using cavability estimation method.Based on solid and block model of each region divided by ore or rock and the value of each parameter in each block,cavability estimation 3D model of Jinchuan No.3 mine area was built.Based on the 3D model,the grading results of orebody cavability in Jinchuan No.3 mine area indicate that ore and rock cavability belong to extremely apt-medium-sized caving.The result is in conformity with reality. |
