| Geographic Information System (GIS) has been widely used in the mining industry through the various aspect in the process, one hand, powerful features of GIS brought a lot of convenience for the design and production of mine, on the other hand with the development of mining GIS technology in the growing terminal, sharing requirements of space information between the GIS become more and more,it Demanding more agreement of the interoperability, so spatial information interoperability of mine GIS has become an important research in the field of interoperability.This paper studied on the issues about GIS interoperability as the follow:(1) Analysised of the data mining space dimension, the corresponding data structure and the characteristics of the structure of spatial data, proposed the approach of establishment of the model of mine space information. on the basis of studying the OGC spatial data model and related services.(2) Analysised of the structure of kinds of GIS and the differents of ardware and software architecture and and the approach of transform of the GIS and mobile GIS. analysised of the differents of the strucature of data of spatial information of differents kinds of GIS.(3) On the basis of analysising of kinds of GIS terminal and spatial information ,I established the model of GIS interoperability between the GIS system and parsed the interoperability model in detail with.And established interoperability ways and protocol of communication on the basis of GML.(4) In the end of the paper, validated the interoperability model between the mapinfo and ArcGIS with the example of the state map of luoyang molybdenum oremining.The interoperability model in this paper is the new attempt for the study of Mine GIS,the verifying said that the interoperability model had some practical value, it could provide reference information for the sturctuction of Mine.
