基于钻孔岩心数据的矿体建模与可视化方法

An orebody modeling and visualization method based on core drill data

针对地质矿产勘探的钻孔岩心数据的矿体建模和可视化需要,设计了一种直观有效的钻孔岩心数据存储的多元组表达结构和分层滤波操作。针对矿体模型,基于包围盒的单元分解模型,使用包围盒中的体元实现矿体的离散化。利用有限的钻孔岩心数据,通过钻孔轨迹生成和地质分层剖面的外推,给出了一种基于体元矿物含量插值的矿体重构算法。最后,通过实际勘探区域的钻孔数据,给出了可视化实验,证明了方法的有效性。

Aiming at the enormous drill core data,this paper designed an intuitionistic and effective manner of tuple presentation,and performed a filtering operation on it. Aiming at the orebody,basing on the unit decomposition model,it discretizes the orebody with the voxels in the bounding box. With limited drill core data,it puts forward an orebody reconstruction method based on voxel mineral abundance by drill track generation and geological section extrapolation. Finally,it provides the result of visualization experiment with the real exploration area's drill core data and proves the effectiveness of this method.
