Abstract: Mining rights setting is an effective method to carry out the development of mineral resource in the national key exploration area.In the process of macro planning of mining rights,the rationality of each mining right will be thought about as much as possible in order to guarantee the final owner’s legitimate interests.This paper analyzes the business requirement of goal system and spatial analysis methods of combining quantitative and qualitative systematically..It introduces the aided system for mining rights which be designed and implemented based on GIS.Those basic data such as geographic data,geological data,geophysical data,geochemical data,mineral data and remote sensing data provides strong support for this system.This system can call the functional interfaces of GIS components to implement analysis function flexible.The setting for the proposed prospecting and the proposed mining rights within the key exploration area will be completed quickly by the interactive operations of aided system with 'What you see is what you gain’ feature.The system is suitable to all aspects of the mining rights set include the development and review phase.At last,quantitative and qualitative analysis will compose a comprehensive analysis result for mining rights set.The solutions of second 31 national key exploration areas have already completed using this system.The practice result shows that the system does not ensure the quality of final data,but also improve the efficiency of work greatly.Now the system has been used in the compose works for the solution of third batch’s key exploration area.And some provinces begin to use it to do a variety of mining rights setting with different level within their jurisdiction.
