针对标准化煤矿数据模型欠缺导致的煤矿数据利用效率低、数据共享少等问题，研究了煤矿三维空间多元数据关系及其属性数据规划；给出了从采掘工程平面图到巷道三维建模的过程及算法，形成了基于ORM映射的煤矿数据模型，并在WebGL技术体系下进行了三维模型输出。结果表明：建立的空间数据模型存储、利用效率高，能够为矿山安全信息化智能决策的数据利用及分析提供支持。

Aiming at the problems of low efficiency of coal mine data utilization and less data sharing caused by the lack of standardized coal mine data model, this paper studies the three-dimensional spatial multivariate data relationship and attribute data planning of coal mines. The process and algorithm from mining engineering plan to tunnel 3D modeling are given, the coal mine data model based on ORM mapping is formed, and the 3D model is output under WebGL technology system. The results shows that the spatial data model established in this paper has high storage and utilization efficiency, and can provide support for data utilization and analysis of mine safety information intelligent decision-making.
