以桂西-滇东南锰矿为例,介绍了矿产资源预测评价数据库的建立方法。在分析地质数据的多元性、分布性、多尺度、遗留性等特点的基础上,设计了矿产资源预测评价数据库的整体框架,主要包括:1)“纵向分层、横向分块”的数据库层次结构;2)以目录、文档、图件、表格的数据分类方法建立的“树状目录”式的数据库模型;3)符合“树状目录”式地质资料检索习惯和管理模式的基于角色的数据库访问控制。结合桂西-滇东南锰矿预测评价的应用,提出了基于统一“数据服务接口”的异构空间数据库和基于B/S和C/S混合模式的数据库系统架构,为基于GIS的锰矿成矿规律、找矿模型与综合评价研究提供了统一的、标准化的数据平台支撑。
Taking the western Guangxi and southeast Yunnan manganese ore as an example, this paper introduced the establishment method of mineral resources prediction and evaluation database. Based on the analysis of the characteristics of the diversity, distribution, multi-scale and legacy of geological data, the overall framework of the mineral resources prediction and evaluation database is designed, which mainly includes: 1) “vertical stratification and horizontal subdivision” Database hierarchy; 2) “Tree catalog” database model based on data classification of catalogs, documents, maps and tables; 3) Consistent with “Tree catalog” geology data retrieval habits and management Mode based on the role of database access control. Combined with the application of the prediction and evaluation of manganese ore in western Guangxi and Guangxi, a heterogeneous spatial database and a database system architecture based on B / S and C / S mixed mode are proposed. Based on GIS, Mine law, prospecting model and comprehensive evaluation of research provide a unified, standardized data platform support.
