3d data model of mine underground space is the key and difficulty of research on mine 3D GIS. In view of the existing problems of coal mine underground 3D spatial modeling, the whole mine underground space is described as an abstract models. Firstly, One concepts, dynamic field frame are introduced according to the relation between real mine underground space model and digital model. Secondly, there are two kinds of objects are proposed: project objects and geological objects in the real geographical world. Based on the relation between the real and the digital geographical world is described by UML languages, an integrated data model is put forward. In this model, the project objects using regular geometric model and the geological objects using TIN surface model, are united into the same data model by the dynamic field frame, and at last the hierarchical system of class is list.
