【目的】常规的二维平面制图软件受制于技术特性无法满足三维地质建模需求,本研究以非洲坦桑尼亚境内某石墨矿勘查项目为研究对象,以地质工程师的专业解译为指导,基于3DMine软件进行矿体三维建模,验证三维地质建模技术在固体矿产资源勘查方面上的应用效果。【方法】首先,依据原始地质资料建立勘查工程数据库。其次,采用剖面法、实体法等建模方法,构建矿体实体三维模型,系统介绍了三维环境下的地质建模全流程和关键环节。【结果】实现了可视化条件下将地质解译转化为对复杂矿体的精准模拟与表达。【结论】应用实践表明,3DMine软件操作简便、算法先进、模型可靠,能够直观、高效、精确地将地质认知与判断进行三维几何图形数字化模拟。在地质勘查项目中应用三维地质建模技术,有助于充分挖掘勘查数据的利用价值,提升勘查工作的信息化水平。

[Purposes]Conventional 2D planar mapping software is limited by its technical characteris-tics,falling to meet the demand for the application of 3D geological modeling.Taking a graphite ore ex-ploration project in Tanzania,Africa as the research object,guided by the professional interpretation of geological engineers,this paper carries out 3D modeling of ore bodies based on 3DMine software,which verifies the application effect of 3D geological modeling technology in the exploration of solid mineral re-sources.[Methods]Firstly,this paper establishes an exploration engineering database based on original geological data.Then,using modeling methods such as section method and entity method,a three-dimensional model of the ore body is constructed,which systemqtically introduces the entire process and key links of geological modeling in a three-dimensional environment.[Findings]The transformation of geological interpretation into precise simulation and expression of complex ore bodies under visual condi-tions was realized.[Conclusions]The application practice has shown that 3DMine software is easy to op-erate,advanced in algorithm,reliable in model,and can intuitively,efficiently,and accurately simulate geological cognition and judgment in three-dimensional geometric graphics digitization.The application of three-dimensional geological modeling technology in geological exploration projects is of great help in fully exploring the utilization value of exploration data and improving the informatization level of explora-tion work.
