Abstract: Energy and mineral resources supply is related to national economic security, the construction of Mineral Resource Security Dynamic Analysis System (MRSAS) for dynamic evaluation of China's future mineral resource security is of great significance to the national economy.The system of mineral resources is based on the State Survey Database of Mineral Resources, and the integrated mining field survey data are used to build the big data platform of mineral resources.The system built on security evaluation of each key technology includes evaluation mathematical model algorithm and computer program, and the model is divided into a market economy model under the conditions of occupancy resources availability, future unused resources availability model, commodity prices forecast model, consumption prediction model, and the security analysis and decision support model.The system is divided into the database management system, the availability analysis subsystem, the security dynamic analysis subsystem, and the decision support system.The implementation of dynamic simulation of future resource supply and demand situation is based on parameters such as mineral species, scale, market price and transportation, etc.An analysis of the future resource would guarantee level support decision-making and the national economic construction.
