Abstract:With the development of digital information technology in mining industry, the concept of DM(Digital Mining) and MGIS(Mining Geographical Information System) are becoming the research focus but not perfect. How to effectively manage the dataset of geological, surveying and mineral products grade is the key point that concerned the sustainable development and standardized management in mining industry. Based on the existing combined GIS and remote sensing technology, we propose a model named DMMIS (Digital Mining Management Information System), which is composed of the database layer, the ActiveX layer and the user interface layer. The system is used in Laozhaiwan Gold Mine, Yunnan Province of China, which is shown to demonstrate the feasibility of the research and development achievement stated in this paper. Finally, some conclusions and constructive advice for future research work are given.
Key words: Digital mining,Geographical Information System,Remote Sensing, Laozhaiwan Gold Mine
1. 引 言
信息技术的发展给全球采矿业带来巨大的冲击,在这个“数字化”大发展的时代,中国
的采矿业也在从劳动密集型向信息化方向发展。在“数字地球”、“数字中国”等概念提出后,1999年,在首届“国际数字地球”会议上,DM(Digital Mine数字矿山)概念首次登场,随后MGIS(Mining Geographic Information System,矿山信息系统)相关技术相继出台,成为数字矿区和数字中国的一个重要组成部分。数字矿山建设的总体目标是实现矿山的“高效、安全、绿色与可持续”发展,对海量、异质、异构、多维、动态的地质、测量及矿山图形和属性数据实现科学有序的组织和管理维护,并提供直观的三维可视化表达等功能,使这些信息实现分布式的共享、协同和重复性的应用,为矿山的规划、生产、经营、管理提供保障和科学决策依据。
老寨湾金矿区位于东经104°52′25〞,北纬23°49′36〞,地处中国云南省文山州广南县。目前该矿的首采区矿石量的服务年限仅为10年,为保持老寨湾金矿的可持续开采,管理接替资源和矿山后期扩建后金矿地质、测量、勘查等信息的有效管理以及现阶段矿山的科学运营,建立综合性的矿山管理信息系统是非常必要的。

2.1. 系统框架设计
基于矿山运营和发展的双重需要,构建了一套集业务管理系统(management information system)和办公自动化(office automation)系统以及智能化的查询分析决策支持系统(decision-making support system)为一体的数字矿山管理信息系统DMMIS (Digital Mining Management Information System)。系统的总体框架如图1所示:
