摘要
运用分形理论对下庄矿田控矿断裂的空间分布特征研究的结果表明,控矿断裂的空间分布具有自相似性特征,分形理论可以定量地描述控矿断裂的分布规律。应用盒计维数法计算了控矿断裂空间分布的分数维值,并对不同成矿构造区的分数维特征进行了比较,探讨了分数维值的物理意义。实际资料计算结果显示,网格数目与尺度有很好的相关性,其相关系数均达0.99以上。
Spatial distribution characteristics of the ore-controling faults in Xiazhuang uranium ore field are studied by using fractal theory in this paper. The results show that the spatial distribution are in selfsimilarity statistically and the distribution regularity can be quantitaively described bY fractal theory. Through utilization of grid chart method, the fractal dimensions of spatial distribution of ore-controling fault are calculated. In addition, properties of fractal dimension in different sub-area are compared and physical significance of fractal dimension is explored in this paper. Real datum computation shows that gridding counting number correlates to the scale very well with a correlation coefficient of more than 0.99.
