为准确掌握自然崩落法崩落矿岩流动特性,提出属性块体建模与随机介质理论相结合的方法,进行崩落矿岩流动模拟.建立属性块体模型拟合目标区域,实现目标区域离散化;建立适宜程序实现的颗粒体数据结构和随机介质空位传递模型;提出放出指数和块度指数概念.分别模拟和分析固定目标放矿区域、不同放矿高度以及不同块度条件下的矿岩流动,并在数字矿山软件平台上用C++编程语言予以实现.结果表明:该方法得到了崩落矿岩流动过程中品位变化及形态发育规律.

In order to accurately grasp the flow characteristics of ore and rock of block caving, a new method that combining attribute block model with stochastic medium theory was proposed. The procedure of simulation flow is as follows: attribute block model was established to fit and discretize target region. Block attributes were obtained by attribute interpolation technique. A proper flow model for programming was established. The concept of draw-out index and block index was put forward to analyze the flow characteristics of the rock under differen...
