摘要
数字矿山的提出,给煤矿信息化建设带来了新的机遇和挑战。在对基于分层和基于地理特征的空间数据组织方式及元数据技术深入分析的基础上,针对煤矿多要素、多层次、多资源和多领域的复杂系统,采用地理本体的思想进行煤矿的认知表达,并由此提出了基于地理本体的煤矿地测数据组织方法。通过对煤矿地理本体的建模,建立了更能客观反映煤矿地理实体各个层次体系的概念模型,根据已有的煤矿概念和多元空间数据集之间的映射关系,重构地理本体支持下的煤矿空间数据库,从而实现煤矿多源空间数据一体化集成与管理,对煤矿涉及到的多源空间数据进行了有效的组织,有利于数据的共享和互操作。
The proposal of ＂Digital Mine＂ has brought new opportunities and challenges for the informationization construction in coal mines.This paper used the idea of geographic ontology to represent the coal mine,and put forward a new geospatial organization method based on geographic ontology,the analysis of layering-oriented and feature-oriented way of spatial data organization,as well as the metadata technology.The coal mine ontology is modeled which includes a conceptual model reflecting the hierarchy of the coal mine,then a spatial database of the coal mine based on geographic ontology is reconstructed according to the mapping relationship between coal mine concepts and exiting multi-source geospatial datasets.By this way,the integration and management of the spatial data of the coal mine can be realized,and the multi-source spatial data of coal mine was well organized.And it is good for the semantic sharing and inter-operation of the spatial information.
