基于GIS的矿山三维地质建模方法

GIS-Based 3D Geological Modeling Method for Mine

矿山三维地质建模是数字矿山的核心组成部分,在地质、采矿、岩土工程等诸多领域日益得到重视。在综合分析三维地质数据模型的基础上,提出了GIS可描述和GIS不可描述数据模型的分类,并在GOCAD和ArcGIS平台下构建了基于GIS的多元、多方法集成的矿山三维地质建模方法。针对GIS不可描述数据模型提出了面向对象的聚合派生法,并通过Geodatabase建立了两平台的关联和模型的更新。通过现场实例应用表明,该方法保持了数据在空间和时间上的一致性,为矿山安全生产管理提供了有效和可靠的空间数据以及可视化的支持。

3D geological modeling of mine is an important part of constructing digital mine, and attracts more and more attentions in many fields such as geology, mining, geotechnical engineering and so on. On the basis of comprehensively analyzing 3D geological data model, the data models were classified in terms of whether they can are described with GIS,and 3D geological modeling for mine based on multi -source, multi -method integration was implemented on the platforms of GOCAD and Are＇GIS. For the GIS -indescribable data models, an aggregation -derived method was presented, and Geodatabase was adopted to communicate between two platforms and updates models. The practical example showed that the proposed method can keep a spatio - temporal consistent representation of data, and offer an effective and reliable spatial data and visualization support for the safety management in production of mine.
