基于多面函数的煤层界面插值及其可视化研究

Research on coal seam interface interpolation and visualization based on multi-quadic function

为了在构建三维矿床模型过程中,形成最佳逼近的煤层界面模型,本文将多面函数理论引入到煤层界面插值中。根据煤层的赋存条件以及原始采样数据的分布特点提出了选择核函数的适用条件。以某矿的钻孔数据为样本,通过3种核函数的对比分析,实现了煤层界面的空间插值以及三维显示,比较真实的反映了矿床的基本特征,为矿床地质模型的建立提供了有力的数据支撑。

In order to reach the best approximation of coal seam when establishing 3D geological model, a new method was proposed to interpolate its interface based on multiquadic model theory. The kernel functions was selected in the different occurrence condition of coal seams and the distribution features of primary data. The coal seam interpolation is realized by a mine borehole, and the visual effect is compared and analyzed using three kernel functions, which is 3D displayed by AutoCAD, the research achievements provide strong data support for the geology model construction.
