基于Surpac的贵州水银洞金矿Ia2矿体金品位模型及分形结构特征
|
摘要
以贵州贞丰水银洞金矿Ia2矿体为研究对象,整合二维地质资料,利用Surpac软件建立矿体三维地质模型。以此模型为基础,直观地反映矿体的几何特征,有效把握矿体空间特征,通过与构造蚀变体(SBT)形态相比较,可以看出矿体产出受SBT控制。用距离幂次反比法对品位进行估值,建立块体模型,用不同颜色直观展现矿体品位的分布情况。对Au品位的分形结构特征进行研究,多分数维反映了多次矿化时间的叠加,分数维个数与主要矿石类型相对应。研究成果利于更好地利用地质矿产资料和矿产资源。
Taking the Ia2 ore body of the Shuiyindong gold mine in Guizhou Province as the research object,this paper integrated two-dimensional geological data and established a 3D ore body model by Surpac software. Based on this model,the geometric characteristics of the ore body were visually reflected,and their spatial characteristics were grasped. By comparing with the morphology of the Shi Bian Ti( SBT),it can be seen that the ore body output is controlled by SBT. The grade level was estimated by the distance power inverse ratio method,and a block model was established to visually display the ore grade distribution in different colors. The fractal structure characteristics of the gold grade were studied. The multi-fractional dimensions reflect the superposition of multiple mineralization,and the number of fractal dimensions corresponds to the main ore type. The research results are conducive to better use of geological mineral materials and mineral resources.
