China is the world's most populous country , and the total mineral resources belong to the resources in the country , but per capita in poor countries , per capita mineral possession of less than half of the world level , into the 21st century , to ensure sustainable economic development of the mineral resources grossly inadequate. The degree of development of mineral resources , reflecting the important signs of the progress of human society , and science and technology level . It directly restricts the speed of development of our national economy , while related to the realization of the strategic objectives of China in the 21st century , which are of great significance for rational use of resources , increase social wealth , and improve economic efficiency , protect the natural ecological balance . The delafossite Tonglushan Daye Nonferrous Metals Corporation, under the backbone of the mine , but also China's nonferrous large-scale mines one . Mine produced using gel, joint mining , open pit mining stope north or south . Due to the principle of historical factors , mining this off first South open pit North open pit . One of the problems of the current mine production : South open pit will be the end of the 2005 mining start North open pit where , in order to make mining economic benefits , social and environmental benefits to maintain optimal ? Against Tonglushan delafossite North open pit where to start optimal collect a large copper mine production based on actual data for mine production in the presence of the ambiguity and complexity of the proposed use of the fuzzy multi- attribute decision-making method for multiple technology feasible The economically rational program evaluation . In a large number of multi-attribute decision model study, research and fuzzy multi-attribute decision model based on the analysis and comparison of each model proposed decision-making model for the development of mineral resources , and in-depth research , the model has been improved , making the model resolution further improved. On the basis of the analysis of the decision-making model applied to Tonglushan delafossite The results show that : the scientific method is simple, accurate, decision-making provides a reasonable basis for the North open pit start .
