| 摘 要： | 以三山岛金矿-510中段和-555中段为例,基于结构面实测数据,利用Matlab对结构面特征进行统计模型,进而实现了岩体裂隙网络Monte-Carlo模拟。然后结合分形理论确定了岩体质量的分维值。研究表明,-510中段和-555中段F3以北的岩体稳定性要好于F3以南的岩体稳定性,从定性和定量的角度对岩体质量进行了分析,为矿山的安全生产提供了一定的依据。

| Abstract: | Take the - 510 level and - 555 level as the example, statistical models of rock mass discontinuity characteristics are obtained based on site data via Matlab. Then the Monte-Carlo network simulation of rock fissures is achieved. Based on the fractal theory, the fractal dimension is decided. The study shows that the stability of north of F3 is better than that south of F3, with regard to the two levels. And both qualitative and quality analysis are given, which provide some proofs for mine security. |
