煤地质学元数据标准化研究

在详细分析煤地质科学数据自身特点和应用目标的基础上，阐明了制定煤地质学元数据标准的必要性和可能性.借鉴“地质信息元数据标准”，分析了煤地质学元数据标准的基本功能和主要内容，选择了合适的元数据标准产生规则，确定了简明扼要的煤地质学元数据概念结构图，在中国高校地学创新平台“中国煤炭资源特性数据库”得到初步应用.提出 “煤地质学元数据标准”设计方案，具有全面性、针对性、简洁性等特点，能够满足煤地质科学平台标准化的需求.

The research for standardization of coal geology metadata

Based on the detailed analysis of the coal geology data characteristic and applied goal,the necessary and probability about establishing coal geology metadata were clarified.The metadata standard for geology informa- tion was used for reference.The function and content of the coal geology metadata standard were analyzed.The ap- propriate rule about metadata standard was chosen.The configuration figure of coal geology metadata was brought forward.Coal geology metadata was used in coal quality database of China.The project of metadata standard for coal geology was brought forward,which is of general,pertinence and terseness.It can content the standardization requirement of the platform about coal geology.
