Application of data warehouse technology in digital mine information system

摘要

With industrialization process rapidly speeding up in our country and the dramatically growing of demands about mine development, people pay more attention to reasonably explore and effectively make use of mine resource, so it is priority to research the construction of digital mine. If data warehouse technology has been applied to the present mining industry, a new perspective to the analysis of mining data processing can be got, according to the requirements of the mining, on the basis of data reorganization and data storage, through on-line analysis processing and data mining techniques, hidden depth information in the huge amounts of data can be found; it can reduce repeat study and improve efficiency, and can provide more robust security decision supporting for mining services. The paper presents a new function hierarchy of digital mine information system based on data warehouse technology.
