| 摘 要： | 以黔东北锰矿矿集区的李家湾-高地-道坨超大型"大塘坡式"锰矿床为例，探讨了在开展勘查地质大数据的特征和结构分析的基础上，厘定事实表和维度表，进而通过对勘查数据的收集、提取、ETL操作，并应用OWB工具建立锰矿山勘探数据的数据集市的思路与方法。进而探讨了以所建立的数据集市为数据支撑平台，建立黔东北超大型锰矿床高精度三维地质模型的途径。该矿床三维地质模型汇集了海量的空间数据与属性数据，是锰矿矿山异质异构勘查开发大数据的有效载体。基于该精细、全息的矿床三维地质模型，不但可以直观反映矿床和矿体特征，而且可以作为矿山管理及其深部和外围找矿预测的可视化分析工具。

Three-dimensional geological modeling of manganese deposits based on exploration big data and data market |
| |
| Abstract: | Taking Lijiawan-Gaodi-Datuo super-large "Datangpo" manganese deposit in northeastern Guizhou as an example, this paper discusses the idea and method of establishing a data market of manganese mine exploration data through collecting, extracting and ETL operation of exploration data based on the analysis of the characteristics and structure of large geological data. Furthermore, the paper describes the way to establish a high-precision three-dimensional geological model of super-large manganese deposits in northeastern Guizhou based on the established data market. The three-dimensional geological model of the deposit condenses a large amount of spatial data and attribute data, and is an effective carrier for large data of heterogeneous exploration and development in manganese mines. Based on the fine and holographic three-dimensional geological model of the deposit, the model not only can directly reflect the characteristics of the deposit and orebody, but also can be used as a visual analysis tool for mine management and prospecting prediction in deep and peripheral areas. |
