川西四家寨金矿三维模型对找矿预测的启示

随着浅地表矿开采殆尽，深部隐伏矿体的寻找与预测成为当前主要研究方向，计算机数据模拟技术的快速发展与应用使得三维地质建模技术不断发展，对深部矿体的展示以及矿产勘查预测能够起到显著的辅助作用。使用Surpac三维可视化矿山软件，利用已有矿山剖面资料建立川西康定四家寨金矿的矿体三维模型、地表三维模型以及断层三维模型，形象地展示出矿体展布特征及矿体、地表及切割矿体断层的三维空间分布关系，并根据矿体三维模型空间延伸规律及断层切割作用分析。结果表明：在矿体南侧及南侧深部具有很好的找矿前景。根据前期收集到的地质资料分析对比，可见Surpac能够较好地模拟矿体形态，可以对矿体向外的延伸进行预测，为川西四家寨金矿的进一步矿产勘查和矿体预测提供可视化证据。

The enlightenment of the three-dimensional model of Sijiazhai gold deposit in western Sichuan Province to prospecting prediction

With the exhaustion of shallow surface ore, the search and prediction of deep hidden ore bodies has become the main research direction at present. The rapid development and application of computer data simulation technology makes the continuous development of 3D geological modeling technology, which can play a significant auxiliary role in the display of deep ore bodies and mineral exploration and prediction. Using Surpac 3d visualization mine software, using the existing mine profile data established the west kangding four village gold ore body 3d model, surface 3d model and fault 3d model, vividly shows the ore body distribution characteristics and ore body, surface and cutting ore body fault three-dimensional spatial distribution relationship, and according to the ore body three dimensional model space extension and fault cutting analysis, the results show that the ore body south and south deep has a very good prospecting prospect. According to the analysis and comparison of geological data collected in the early stage, it can be seen that Surpac can better simulate the shape of the ore body and predict the outward extension of the ore body, and provide visual evidence for further mineral exploration and ore body prediction of Sijiazi gold mine in western Sichuan.
