摘　　要：对分布式关系与空间混合数据库特征进行了分析。使用基于惰性副本控制协议的关系数据同步技术和基于"双向同步复制"的SDE(Spatial Data Engine)空间数据库同步技术,设计实现了分布式关系与空间混合数据库同步组件。在此基础上,结合国内大中型煤矿网络特点,提出并设计了基于分布式数据库的煤矿瓦斯灾害预警软件体系结构,并在MicrosoftC#2.0和ESRI ArcEngine平台中实现。The paper analysed the features of distributed relationship and the spatial mixed database,and designed the synchronous components for realizing the distributed relationship and spatial mixed database with the relationship data synchronization technology based on inertia copy control protocol and SDE （Spatial Data Engine） synchronization technology based on two-way synchronous replication.In combination with the features of networks in the large and medium colliery,the software architecture of gas disaster alarming system was proposed and designed,and which was realized with the platform of Microsoft C # 2.0 and ESRI ArcEngine.
