应用分形理论对滇西北羊拉矿山进行研究,得出其总体断裂分维值为1.413,江边矿段和里农矿段分维值分别为1.181和1.347。通过分析断裂分维值与矿区矿体分布,发现矿区断裂分维值越大,断裂构造发育更为强烈,同时矿体发育更为密集且规模越大。结果表明断裂分维值可以作为判断矿体规模的一项参数。
Based on the fractal theory, the fractal dimension of the overall fault in Shela Mine in western Yunnan Province is 1.413. The fractal dimension values of the Jiangbian and Liunong sections are 1.181 and 1.347, respectively. By analyzing the fracture fractal dimension and the distribution of ore body, it is found that the larger fractal dimension of fractured area is, the more fracture structure is developed, and the ore body is more intensive and larger in scale. The results show that fracture fractal dimension can be used as a parameter to judge ore body size.
