基于GIS矿产资源评价中数据挖掘技术的构建

Construction of data mining technology in mineral resource appraisal

针对矿产资源评价的基本任务是将地质工作中所获取的相关数据与资料,应用地质理论和科学方法,在总结成矿地质条件和成矿规律的基础上,将其转化为矿产资源信息.在基于GIS为主要工具的矿产资源评价系统中,以进行多元地学信息数据空间数据库的建立为基础,构建矿床矿产地质的可视化模型,根据所采集的多元地学信息数据和成矿地质条件及成矿理论之间的关系,进行矿产资源地质构造的空间分析.

The basic task of mineral resource appraisal is applying geology theory and the scientific method to gain the correlative data and information in geological wook. By summing up mineralization geological condition and the foundation of mineralization rule, the mineral resource information are transformed. In the construction of data mining technology based on GIS which as a main instrument in the mineral resource evaluationsystem, and on the foundation, which spatial databases is established for the multiple source geosciences message data, visualization model of ore deposit minerals geology is constructed. According to the relationship between multisource geosciences message data have gained and mineralization geological condition together with mineralization theory, the spatial analysis for mineral resource geologic structure is processed.
