基于目標規(guī)劃的我國銅礦資源開發(fā)模擬研究
[Abstract]:Copper is one of the strategic nonferrous metals in urgent need in China. In recent years, with the rapid development of China's economy, the demand for copper resources is increasing. However, the reserves of copper resources in China are limited, its static reserves guarantee life is less than 7 years, the degree of security is low, and the safety supply capacity is poor. Therefore, how to improve the guarantee degree of copper resources and meet the needs of the current social and economic development is an urgent problem to be solved by the land and resources management department. Under the guidance of the theory of sustainable development, combined with the theory of circular economy, the theory of mineral resources safety, the theory of mineral resources demand and the theory of mineral resources planning, this paper starts from the perspective of mineral resources planning and management. Based on the analysis of the present situation of geological exploration, development and utilization and market operation of copper resources in China, the authors have established a plan to improve the degree of copper resources guarantee. The objective programming model for the development of copper resources in China, which is aimed at meeting the demand of the national economy and improving the safety of copper supply, is studied and simulated. It is concluded that in recent years, the geological exploration of copper resources in China is increasing continuously, and the reserves of copper resources are continuously increasing. The level of exploitation and utilization has been improved continuously, but the uneven distribution of resources and the unreasonable scale structure of copper mine have also greatly restricted the development and utilization of copper deposits. The implementation of national policy and the application of advanced comprehensive utilization technology make the output value of comprehensive utilization increase rapidly. The output and consumption of copper products in China are increasing continuously, but the unreasonable industrial structure of copper industry leads to the unreasonable structure of copper products and the imbalance of supply and demand. Insufficient supply of domestic copper products, leading to high external dependence, increasing trade deficit. According to the simulation results of the target programming model of copper resource development in China, by 2020, the reserves and annual output of copper concentrate in China will double to 20.95 million tons and 3 million tons respectively, on the basis of 2012. The annual import of copper concentrate is about 3.66 million tons, an increase of about 1.3 million tons compared with 2012. Based on the analysis of the present situation of copper resources in China and the result of solving the objective programming model of copper resources development in China, the suggestions for sustainable development of copper resources in China are put forward: strengthening the exploration of mineral resources and improving the support capacity of copper resources; Optimize the industrial structure of copper industry and improve the supply capacity of domestic copper mines.
