Theoretical and Technical Methods of Mineral Resource Supply Base Evaluation and Supply Chain Investigation

Abstract

At present, the COVID-19 epidemic is still spreading around the world, which greatly affects the global supply of mineral resources. Due to numerous resources supply nodes and complex and changeable risk factors, it is urgent to carry out comprehensive research on the supply base, supply node and supply chain of mineral resources from the perspective of production and transportation supply chain. Based on the global perspective and long-term research on risk assessment and countermeasures of global mineral resources, this paper puts forward the concept, connotation and evaluation method of mineral resources supply chain for the first time and traces the whole chain of mineral products from production, transportation and smelting process in space. With the mineral resources supply base as the entry point, the method of determination and comprehensive evaluation of mineral resources supply base based on space technology is established to realize the transformation of the delineation of mineral resources supply base from the traditional planarization to the spatialization. The collation and stipulation of the technical system through the establishment of supply key nodes and supply chain of mineral resources can collate and stipulate supply chain and key knots by systematically taking into consideration the mineral resources supply of the target country, and can utilize the risk evaluation method of the mineral resources supply chain to carry out risk evaluation directed against the supply chain. These measures help the target country wholly grasp hidden risk of the mineral resources supply chain and, according to different forewarning grades, draw up safety contingency plans in accord with different grades and kinds, thus guaranteeing continued and stable supply of mineral resources. © 2021, Science Press.
