数字矿山的数据组织及其不确定性分析

Data organization and uncertainty analysis in digital mine

数字矿山是数字地球的重要组成部分,数据是数字矿山的核心,这些数据的精确与否将关系到矿山的安全生产、合理决策等方面的问题。数字矿山的数据来源广泛,数据极其复杂,因此,采用空间数据仓库技术来处理矿山数据是必要的。本文在分析矿山数据内容、特征的基础上,论述了数字矿山数据的组织,针对矿山数据源、数据入库、数据动态性及数据处理引起的不确定性问题作了分析,并归纳了相应的处理方法。

Digital mine is an important part of Digital Earth. The data is the core of the Digital mine. The data precision affects safe exploitation and reasonable decision-making of a mine. Data warehouse is necessary to manage mine data since the source of the Digital Mine's data is far-ranging and complex. Based on the analysis of mine data's contents and features, the organization process of mine data is described, the main issues of mine data uncertainty are analyzed according to mine data source, data loading to the database, data's dynamic feature and data processes. Meanwhile, the corresponding methods of mine data uncertainty are concluded.
