Abstract: China’s national potential evaluation of mineral resources (2006-2013) is the most systematic and most comprehensive and authoritative survey of nationwide mineral resources. It is also unique in the world and has obtained a large number of innovative achievements. Through the study and development of required data model, the application of software and key technology, and the provision of modern information technology support for the national survey of mineral resources in the whole process, researchers have realized digitization of full information, computerization of work means, GIS operation of prediction processing, quantification of predictions, precision of positioning and prediction, and standardization and integration of achievements. On such a basis, the technological system of designing, development and application has been established around data-model and data-integrating of the mineral resources potential evaluation. This paper briefly describes the main content of this technological system in the hope of sharing the achievements with the readers so as to further the development and perfection.
