摘要

Kriging方法可对离散数据点进行内插和外推,近年来在地质、测绘各方面得到了普遍应用,但Kriging方法中变异函数理论模型的选择和实验变异函数参数的设定大部分依赖于地质工作人员的专业技能,具有一定的客观性. 引入混合蛙跳算法,对Kriging实验变异函数进行优化,提出SFLA-Kriging算法并结合某露天矿钻孔数据进行三维建模. 实验结果标明,SFLA-Kriging算法与传统Kriging方法相比,克服了一般方法的局限性,误差降低27.89%、三维地质模型精度更高.

Abstract

Kriging algorithm can process discrete data with interpolation and extrapolation and it has been applied universally in the field of geology, surveying and mapping etc. But the selection of variogram theory model and the setting of experimental variogram parameters largely depend on the geological staff's professional skills which has certain objectivity. Hybrid leapfrog algorithm was introduced to optimize the Kriging experimental variogram and 3D model was built with proposed SFLA-Kriging algorithm and a certain open-pit mine drilling data. Experiment has shown that, SFLA-Kriging algorithm has overcome the limitation of general methods and has smaller error and higher precision of 3D geological model comparing with the traditional Kriging method.
