According to the characteristics of complicated network and spatial distribution of coal mine power system,Smallworld was used as GIS platform to build a model of the system. Based on object oriented modeling technology,fields and relationships,containing physical and geometric topological,were defined to build mining engineering objects and power system objects model. Substation internal object and an independent coordinate system were added which associated substation with its equipments. Using Magik language,external database access module was developed for dynamic visualizing equipment telemetery information. Taking Huoerxinhe Coal Mine as an example,the model were realized and the module was tested. The results showed that seamless fusion of spatial distribution and primary connection among equipments was realized by the model. It was promoted that the monitoring and management level of underground power system by access telemetry data in GIS platform. At the same time,it was put forward that the future research emphasis included fault source tracing, power cut analysis and other professional functions developed by topological analysis.
