为了使三维地质建模(3DGM)过程中,矿体模型能够动态构建和更新,基于克里格法资源储量估算过程中常用的矿体块体模型,提出了一种新的方法:克里格块体(KrigingBlock,KB)法,根据已经记录地质统计学插值或模拟结果的矿体块体模型,创建符合一定工业指标条件的几何结构模型。以自主知识产权的三维地学信息系统平台QuantyView(原GeoView)为基础对该方法进行了实现,并且成功地在某矿区动态地构建出了不同边界品位条件下的矿体模型。KB法可以完成大多数矿体模型的构建、更新过程。由于空间插值或模拟技术的引入,该方法可以有效地融合多源、多类的软、硬性控矿信息,从而提高建模结果的可信度。此外,它还可以很容易地扩展到3DGM其它类似的领域,如油气分布等。
In order to achieve the dynamical construction and updating of ore-body model in three-dimensional geological modeling(3DGM),a new method named Kriging Block(KB) method was proposed.The basic idea of KB method is to create a necessary mineral geometry structure model based on the block model which is well-known in geo-statistical estimation or simulation for ore-body resources.Based on three-dimensional geoscience information system QuantyView with self-owned intellectual property rights,KB method has been implemented.A case study was carried out to test the validity and practicability of this method,and the test had succeeded in dynamically constructing a series of different ore-body models under the relevant cut-off grades.The proposed method can process most of the ore-bodies in dynamically constructing or updating the resulted ore-body model.As the introduction of geo-statistical estimation and simulation to the modeling procedure,KB method can make full use of the multi-source soft or hard geological data to improve the reliability of the modeling results.Additionally,this method can be easily expanded to other similar 3DGM fields,such as modeling the distribution of oil and gas and so on.
