摘　　要：针对我国煤层气开发利用数据复杂多样、格式各异、分散存储以及海量数据无法充分共享等特点,在充分研究满足信息共享需求的基础上,设计了基于互联网的煤层气元数据管理系统。首先探讨了互联网环境下基于XML的煤层气开发利用元数据标准、元数据自动获取和互联网收割等技术,最后以某煤矿瓦斯地质图、某煤层气数据处理平台报告文档和煤层气利用数据库为例,给出了互联网环境下相应元数据自动生成的实例。本元数据管理系统贯穿了煤层气地质、开发和利用的全生命周期,通过元数据库信息的自动更新,能够实现煤层气信息的及时和有效共享,为煤层气开发利用的动态决策支持服务。According to the complicated and diversity, different format, separated storage of the coalbed methane development and utiliza- tion data in China and the massive data hard to fully sharing and other features, based on the full study to meet the requirements of the in- formation sharing,the coalbed methane metadata management system was designed based on the internet.The paper firstly discussed the metadata standards of the coalbed methane development and utilization, metadata automatic extraction and internet reaping and other tech- nology under the internet environment and based on the XML.In the end, based on mine gas geologic map, a report document of coalbed methane data processing platform and coalbed methane utilization database as the cases,the paper provided the relevant metadata automatic generation case under the internet environment.The metadata management system ran through the full life period of the coalbed methane geology ,development and utilization.The automatic upgrading of the metadata database information could realize the coalbed methane infor- mation sharing timely and effectively and could provide the support services of the dynamic decision making for the coalbed methane devel- opment and utilization.
