摘　　要：地矿数据的质量、数量和更新时效已成为衡量一个国家地质调查工作水准和社会化服务水平的基础标准之一,大数据时代下信息技术的飞速发展推动了地矿行业的数据资源共享和信息化服务水平的提高,但是,地矿行业属于传统行业,信息化水平不高、智能化水平更是欠缺。本文从地矿数据资源如何服务于经济社会发展进行探讨,重点论述了四大关键技术:1)地上、地下一体化的三维地质支撑软件;2)多源、多尺度空间数据融合;3)基于时空数据模型的地质大数据管理;4)多主题数据仓库构建和基于数据仓库的联机时空数据挖掘。The quality,quantity and update timeliness of geological and mining data have become one of the basic standards for measuring the level of geological survey work and social service levels in a country.The rapid development of information technology in the era of big data has promoted the sharing of data resources and information in the geological and mining industry.However,the geological and mining industry has been a traditional industry for a long time,and the level of informatization is not high,and the level of intelligence is even more lacking.This article discusses how geological and mining data resources serve economic and social development,focusing on the four major key technologies:(1)3D geological support software integrating above and below ground;(2)multi-source and multi-scale spatial data fusion;(3)Geological big data management based on spatio-temporal data model;(4)Multi-topic data warehouse construction and data warehouse based online spatio-temporal data mining.
