摘要
针对三维空间数据插值方法的研究在技术上难度较大、结构上程度复杂的特点,利用已有的二维空间数据插值长期发展提供的理论和实践经验,以地质统计学为理论基础,详细研究了三维普通克立格(Kriging)块段插值方法的关键步骤。同时,介绍了建立非层状矿体块段模型的关键技术和主要方法。针对插值过程中信息点的数据搜索问题提出了真三维空间的椭球扇区搜索方法,使计算结果更加精确。最后,从底层开发了块段建模可视化软件,在某矿山得到了验证,对非层状矿体模型的模拟和矿体储量计算起到了一定的指导作用。
In view of the characteristics of great technical difficulty and complex structure of the study of 3D spatial data interpolation method, by taking advantage of the theoretical and practical experience provided in the long term development of the existing 2D spatial data interpolation, and on the theoretical base of geostatistics, detailed study is made on the key steps in 3D common Kriging block interpolation method. Meanwhile, the key techniques and main methods in establishing non-laminated orebody block model are presented. In light of the problem of data search of information points in interpolation process, an elliptical sector search method for real 3D space is proposed, making the calculation results more accurate. Finally, visualization software for block modeling is developed from the bottom layer, which has been verified in a mine and can be of certain guidance significance to the modeling of non-laminated orebody and orebody reserve calculation.
