Abstract: Based on the analysis of coalmine safety information management and coalmine workflow, the authors set forth the concept and structure about the platform of coalmine safety information sharing and decision-making on web according to the theories on gray geographical information system and computer supported cooperative work. From the viewpoints of information sharing and collaborative work, the authors put forward gray spatial information sharing model based on dynamically correcting metadata and collaborative model about coalmine safety decision-making on web, and discuss some correlative and key technologies in realization and application of the platform according to data retrieval, data transmission, data storage, data sharing and data processing.The platform is well implemented in Zaozhuang Mining Group Company.

Key words: coalmine safety, information sharing model, decision-making on the web, collaborative model

摘要： 针对煤矿安全信息管理存在的问题与煤矿工作流的特点，结合灰色地理信息系统与计算机支持下的协同工作（CSCW）理论提出了煤矿安全信息共享与网络决策平台的概念与体系结构，并从平台实现与煤矿安全数据角度阐述了基于元数据动态修正的灰色空间信息共享模型、煤矿安全网络决策的协同工作模型和相关的关键技术。介绍了平台在枣庄矿业集团的应用。
