Abstract: The establishment of open-pit application model library is a support system to optimize the management of geospatial decision for the open pit production，its function is to achieve the computer decision support management of the geology，mine plan，open-pit mining and land reclamation ecological construction through model.The establishment of model base system in open pit can solve the theoretical and technical issues to develop a common platform for open-pit mine model base system，can efficiently manage the model of open-pit at all phases，and provide a reasonable，reliable auxiliary decision support platform for information management in future.

Key words: Model base system, Model base management system, GIS
