针对广东省已建成的铀矿钻孔数据库系统在工程地质分析、解释全过程方面未能实现数字化可视化分析的空间管理问题,该文提出以地理信息系统平台为基础,根据铀矿成矿、勘探、储量估算的特点,建设三维铀矿建模地理信息系统平台。实现了铀矿勘查数据库建库、矿区地质成图、矿体圈定、矿床地质建模、品位估计和储量估算等全过程的数字化、可视化的查询与分析;结合地表建模及可叠加遥感技术,实现了地上地下全方位矿区立体建模。实践表明,利用该系统重构的地质矿体真实可靠,与传统解释方法基本一致,符合铀矿成矿原理。
Aimed at the problem of spatial management of digitalized visualization analysis of uranium mine drilling database system that has been built in Guangdong Province in the aspects of engineering geological analysis and explanation of whole process, this paper proposes that based on the platform of geographic information system, , The characteristics of reserves estimation, construction of three-dimensional uranium modeling geographic information system platform. The digital and visual query and analysis of the whole process of database construction of uranium exploration database, geological mapping of ore district, delineation of ore body, geological modeling of deposit, grade estimation and reserves estimation are realized. Combining with surface modeling and superimposed remote sensing technology, To achieve a three-dimensional all-dimensional underground mine modeling. Practice shows that the geological orebody reconstructed by this system is reliable and reliable, which is basically consistent with the traditional interpretation method and in line with the ore-forming principle of uranium deposits.
