露天矿复杂地质体中的各种地质信息,包括地表地形、地下水位、地层断面、节理、风化带分布等,都可以通过野外勘探实测或检测仪器获得,但一般都是散乱数据,而且数量有限。利用这些稀疏、有限、不规则的数据建立三维地质模型难以描述矿山地质体的实际情况,以此模型进行的空间分析难以达到理想的效果。为了利用这些原始数据建立比较理想的地质模型,必须分析原始数据间的联系和规律性,结合地质学原理和相关的地质条件选择合适的插值方法来处理原始数据。
All kinds of geological information in complex geological bodies of open-pit mines, including surface topography, groundwater level, stratigraphic cross-section, joints and weathered belt distribution, can be obtained through field exploration and measurement or testing instruments, but are generally scattered data and limited in number . The use of these sparse, finite and irregular data to establish three-dimensional geological model is difficult to describe the actual situation of the mine geological body, the model of the spatial analysis is difficult to achieve the desired effect. In order to establish the ideal geological model by using these original data, we must analyze the relationship and regularity of the original data, and select the appropriate interpolation method to deal with the original data according to the geology principle and the related geological conditions.
